The diagram on Page 1 shows the two clock domains that make

up the ADSP-2148x processors. The core clock domain contains

the following features:

• Two processing elements (PEx, PEy), each of which com-

prises an ALU, multiplier, shifter, and data register file

• Data address generators (DAG1, DAG2)

• Program sequencer with instruction cache

• PM and DM buses capable of supporting 2x64-bit data

transfers between memory and the core at every core pro-

cessor cycle

• One periodic interval timer with pinout

• On-chip SRAM (5 Mbit) and mask-programmable ROM

(4 Mbit)

• JTAG test access port for emulation and boundary scan.

The JTAG provides software debug through user break-

points which allows flexible exception handling.

The block diagram of the ADSP-2148x on Page 1 also shows the

peripheral clock domain (also known as the I/O processor)

which contains the following features:

•IOD0 (peripheral DMA) and IOD1 (external port DMA)

buses for 32-bit data transfers

• Peripheral and external port buses for core connection

• External port with an AMI and SDRAM controller

•4 units for PWM control

• 1 memory-to-memory (MTM) unit for internal-to-internal

memory transfers

• Digital applications interface that includes four precision

clock generators (PCG), an input data port (IDP/PDAP)

for serial and parallel interconnects, an S/PDIF

receiver/transmitter, four asynchronous sample rate con-

verters, eight serial ports, and a flexible signal routing unit

(DAI SRU).

• Digital peripheral interface that includes two timers, a

2-wire interface (TWI), one UART, two serial peripheral

interfaces (SPI), 2 precision clock generators (PCG), pulse

width modulation (PWM), and a flexible signal routing

unit (DPI SRU2).

As shown in the SHARC core block diagram on Page 5, the

processor uses two computational units to deliver a significant

performance increase over the previous SHARC processors on a

range of DSP algorithms. With its SIMD computational hard-

ware, the processors can perform 2.7 GFLOPS running at

450 MHz.

FAMILY CORE ARCHITECTURE

The ADSP-2148x is code compatible at the assembly level with

the ADSP-2147x, ADSP-2146x, ADSP-2137x, ADSP-2136x,

ADSP-2126x, ADSP-21160, and ADSP-21161, and with the first

generation ADSP-2106x SHARC processors. The ADSP-2148x

shares architectural features with the ADSP-2126x, ADSP-

2136x, ADSP-2137x, ADSP-2146x and ADSP-2116x SIMD

SHARC processors, as shown in Figure 2 and detailed in the fol-

lowing sections.

SIMD Computational Engine

The ADSP-2148x contains two computational processing ele-

ments that operate as a single-instruction, multiple-data

(SIMD) engine. The processing elements are referred to as PEX

and PEY and each contains an ALU, multiplier, shifter, and reg-

ister file. PEx is always active, and PEy may be enabled by

setting the PEYEN mode bit in the MODE1 register. SIMD

mode allows the processor to execute the same instruction in

both processing elements, but each processing element operates

on different data. This architecture is efficient at executing math

intensive DSP algorithms.

SIMD mode also affects the way data is transferred between

memory and the processing elements because twice the data

bandwidth is required to sustain computational operation in the

processing elements. Therefore, entering SIMD mode also dou-

bles the bandwidth between memory and the processing

elements. When using the DAGs to transfer data in SIMD

mode, two data values are transferred with each memory or reg-

ister file access.

Independent, Parallel Computation Units

Within each processing element is a set of computational units.

The computational units consist of an arithmetic/logic unit

(ALU), multiplier, and shifter. These units perform all opera-

tions in a single cycle and are arranged in parallel, maximizing

computational throughput. Single multifunction instructions

execute parallel ALU and multiplier operations. In SIMD mode,

the parallel ALU and multiplier operations occur in both pro-

cessing elements. These computation units support IEEE 32-bit

single-precision floating-point, 40-bit extended precision float-

ing-point, and 32-bit fixed-point data formats.

Timer

The processor contains a core timer that can generate periodic

software interrupts. The core timer can be configured to use

FLAG3 as a timer expired signal.

Data Register File

Each processing element contains a general-purpose data regis-

ter file. The register files transfer data between the computation

units and the data buses, and store intermediate results. These

10-port, 32-register (16 primary, 16 secondary) register files,

combined with the processor’s enhanced Harvard architecture,

allow unconstrained data flow between computation units and

internal memory. The registers in PEX are referred to as

R0–R15 and in PEY as S0–S15.

Context Switch

Many of the processor’s registers have secondary registers that

can be activated during interrupt servicing for a fast context

switch. The data registers in the register file, the DAG registers,

and the multiplier result registers all have secondary registers.

The primary registers are active at reset, while the secondary

registers are activated by control bits in a mode control register.

Rev. E | Page 5 of 68 | June 2017

Universal Registers

These registers can be used for general-purpose tasks. The

USTAT (4) registers allow easy bit manipulations (Set, Clear,

Toggle, Test, XOR) for all peripheral registers (control/status).

The data bus exchange register (PX) permits data to be passed

between the 64-bit PM data bus and the 64-bit DM data bus, or

between the 40-bit register file and the PM/DM data bus. These

registers contain hardware to handle the data width difference.

Single-Cycle Fetch of Instruction and Four Operands

The ADSP-2148x features an enhanced Harvard architecture in

which the data memory (DM) bus transfers data and the pro-

gram memory (PM) bus transfers both instructions and data.

With the its separate program and data memory buses and on-

chip instruction cache, the processor can simultaneously fetch

four operands (two over each data bus) and one instruction

(from the cache), all in a single cycle.

Instruction Cache

The processor includes an on-chip instruction cache that

enables three-bus operation for fetching an instruction and four

data values. The cache is selective—only the instructions whose

fetches conflict with PM bus data accesses are cached. This

cache allows full speed execution of core, looped operations

such as digital filter multiply-accumulates, and FFT butterfly

processing.

Data Address Generators With Zero-Overhead Hardware

Circular Buffer Support

The two data address generators (DAGs) are used for indirect

addressing and implementing circular data buffers in hardware.

Circular buffers allow efficient programming of delay lines and

other data structures required in digital signal processing, and

are commonly used in digital filters and Fourier transforms.

The two DAGs contain sufficient registers to allow the creation

of up to 32 circular buffers (16 primary register sets, 16 second-

ary). The DAGs automatically handle address pointer

wraparound, reduce overhead, increase performance, and sim-

plify implementation. Circular buffers can start and end at any

memory location.

Flexible Instruction Set

The 48-bit instruction word accommodates a variety of parallel

operations, for concise programming. For example, the

processor can conditionally execute a multiply, an add, and a

subtract in both processing elements while branching and fetch-

ing up to four 32-bit values from memory, all in a single

instruction.

Variable Instruction Set Architecture (VISA)

In addition to supporting the standard 48-bit instructions from

previous SHARC processors, the ADSP-2148x supports new

instructions of 16 and 32 bits. This feature, called Variable

Instruction Set Architecture (VISA), drops redundant/unused

bits within the 48-bit instruction to create more efficient and

compact code. The program sequencer supports fetching these

16-bit and 32-bit instructions from both internal and external

SDRAM memory. This support is not extended to the

asynchronous memory interface (AMI). Source modules need

to be built using the VISA option, in order to allow code genera-

tion tools to create these more efficient opcodes.

On-Chip Memory

The ADSP-21483 and the ADSP-21488 processors contain

3 Mbits of internal RAM (Table 3) and the ADSP-21486,

ADSP-21487, and ADSP-21489 processors contain 5 Mbits of

internal RAM (Table 4). Each memory block supports single-

cycle, independent accesses by the core processor and I/O

processor.

The processor’s SRAM can be configured as a maximum of

160k words of 32-bit data, 320k words of 16-bit data, 106.7k

words of 48-bit instructions (or 40-bit data), or combinations of

different word sizes up to 5 megabits. All of the memory can be

accessed as 16-bit, 32-bit, 48-bit, or 64-bit words. A 16-bit

floating-point storage format is supported that effectively dou-

bles the amount of data that may be stored on-chip. Conversion

between the 32-bit floating-point and 16-bit floating-point

formats is performed in a single instruction. While each mem-

ory block can store combinations of code and data, accesses are

most efficient when one block stores data using the DM bus for

transfers, and the other block stores instructions and data using

the PM bus for transfers.

Using the DM bus and PM buses, with one bus dedicated to a

memory block, assures single-cycle execution with two data

transfers. In this case, the instruction must be available in the

cache.

The memory maps in Table 3 and Table 4 display the internal

memory address space of the processors. The 48-bit space sec-

tion describes what this address range looks like to an

instruction that retrieves 48-bit memory. The 32-bit section

describes what this address range looks like to an instruction

that retrieves 32-bit memory.

ROM Based Security

The ADSP-2148x has a ROM security feature that provides

hardware support for securing user software code by preventing

unauthorized reading from the internal code. When using this

feature, the processor does not boot-load any external code, exe-

cuting exclusively from internal ROM. Additionally, the

processor is not freely accessible via the JTAG port. Instead, a

unique 64-bit key, which must be scanned in through the JTAG

or Test Access Port will be assigned to each customer. The

device will ignore a wrong key. Emulation features are available

after the correct key is scanned.

On-Chip Memory Bandwidth

The internal memory architecture allows programs to have four

accesses at the same time to any of the four blocks (assuming

there are no block conflicts). The total bandwidth is realized

using the DMD and PMD buses (2 × 64-bits, CCLK speed) and

the IOD0/1 buses (2 × 32-bit, PCLK speed).

FAMILY PERIPHERAL ARCHITECTURE

The ADSP-2148x family contains a rich set of peripherals that

support a wide variety of applications including high quality

audio, medical imaging, communications, military, test equip-

ment, 3D graphics, speech recognition, motor control, imaging,

and other applications.

External Memory

The external port interface supports access to the external mem-

ory through core and DMA accesses. The external memory

address space is divided into four banks. Any bank can be pro-

grammed as either asynchronous or synchronous memory. The

external ports are comprised of the following modules.

• An Asynchronous Memory Interface which communicates

with SRAM, FLASH, and other devices that meet the stan-

dard asynchronous SRAM access protocol. The AMI

supports 6M words of external memory in bank 0 and 8M

words of external memory in bank 1, bank 2, and bank 3.

• A SDRAM controller that supports a glueless interface with

any of the standard SDRAMs. The SDC supports 62M

words of external memory in bank 0, and 64M words of

external memory in bank 1, bank 2, and bank 3. NOTE:

This feature is not available on the ADSP-21486 product.

ADSP-21483/ADSP-21486/ADSP-21487/ADSP-21488/ADSP-21489

• Arbitration logic to coordinate core and DMA transfers

between internal and external memory over the external

port.

Non-SDRAM external memory address space is shown in

Table 5.

External Port

The external port provides a high performance, glueless inter-

face to a wide variety of industry-standard memory devices. The

external port, available on the 176-lead LQFP, may be used to

interface to synchronous and/or asynchronous memory devices

through the use of its separate internal memory controllers. The

first is an SDRAM controller for connection of industry-stan-

dard synchronous DRAM devices while the second is an

asynchronous memory controller intended to interface to a

variety of memory devices. Four memory select pins enable up

to four separate devices to coexist, supporting any desired com-

bination of synchronous and asynchronous device types.

Asynchronous Memory Controller

The asynchronous memory controller provides a configurable

interface for up to four separate banks of memory or I/O

devices. Each bank can be independently programmed with dif-

ferent timing parameters, enabling connection to a wide variety

of memory devices including SRAM, flash, and EPROM, as well

as I/O devices that interface with standard memory control

lines. Bank 0 occupies a 6M word window and banks 1, 2, and 3

occupy a 8M word window in the processor’s address space but,

if not fully populated, these windows are not made contiguous

by the memory controller logic.

SDRAM Controller

The SDRAM controller provides an interface of up to four sepa-

rate banks of industry-standard SDRAM devices at speeds up to

SDCLK

. Fully compliant with the SDRAM standard, each bank has

its own memory select line (MS0–MS3), and can be configured

to contain between 4M bytes and 256M bytes of memory.

SDRAM external memory address space is shown in Table 6.

NOTE: this feature is not available on the ADSP-21486 model.

A set of programmable timing parameters is available to config-

ure the SDRAM banks to support slower memory devices. Note

that 32-bit wide devices are not supported on the SDRAM and

AMI interfaces.

The SDRAM controller address, data, clock, and control pins

can drive loads up to distributed 30 pF. For larger memory sys-

tems, the SDRAM controller external buffer timing should be

selected and external buffering should be provided so that the

load on the SDRAM controller pins does not exceed 30 pF.

Note that the external memory bank addresses shown are for

normal-word (32-bit) accesses. If 48-bit instructions as well as

32-bit data are both placed in the same external memory bank,

care must be taken while mapping them to avoid overlap.

SIMD Access to External Memory

The SDRAM controller on the processor supports SIMD access

on the 64-bit EPD (external port data bus) which allows access

to the complementary registers on the PEy unit in the normal

word space (NW). This removes the need to explicitly access the

complimentary registers when the data is in external SDRAM

memory.

VISA and ISA Access to External Memory

The SDRAM controller on the ADSP-2148x processors sup-

ports VISA code operation which reduces the memory load

since the VISA instructions are compressed. Moreover, bus

fetching is reduced because, in the best case, one 48-bit fetch

contains three valid instructions. Code execution from the tra-

ditional ISA operation is also supported. Note that code

execution is only supported from bank 0 regardless of

VISA/ISA. Table 7 shows the address ranges for instruction

fetch in each mode.

Pulse-Width Modulation

The PWM module is a flexible, programmable, PWM waveform

generator that can be programmed to generate the required

switching patterns for various applications related to motor and

engine control or audio power control. The PWM generator can

generate either center-aligned or edge-aligned PWM wave-

forms. In addition, it can generate complementary signals on

two outputs in paired mode or independent signals in non-

paired mode (applicable to a single group of four PWM

waveforms).

The entire PWM module has four groups of four PWM outputs

generating 16 PWM outputs in total. Each PWM group pro-

duces two pairs of PWM signals on the four PWM outputs.

Rev. E | Page 9 of 68 | June 2017

The PWM generator is capable of operating in two distinct

modes while generating center-aligned PWM waveforms:

single-update mode or double-update mode. In single-update

mode the duty cycle values are programmable only once per

PWM period. This results in PWM patterns that are symmetri-

cal about the midpoint of the PWM period. In double-update

mode, a second updating of the PWM registers is implemented

at the midpoint of the PWM period. In this mode, it is possible

to produce asymmetrical PWM patterns that produce lower

harmonic distortion in three-phase PWM inverters.

PWM signals can be mapped to the external port address lines

or to the DPI pins.

MediaLB

The automotive models of the ADSP-2148x processors have an

MLB interface which allows the processor to function as a

media local bus device. It includes support for both 3-pin as well

as 5-pin media local bus protocols. It supports speeds up to

1024 FS (49.25 Mbits/sec, FS = 48.1 kHz) and up to 31 logical

channels, with up to 124 bytes of data per media local bus frame.

For a list of automotive models, see Automotive Products on

Page 66.

Digital Applications Interface (DAI)

The digital applications interface (DAI) allows the connection

of various peripherals to any of the DAI pins (DAI_P20–1).

Programs make these connections using the signal routing unit

(SRU).

The SRU is a matrix routing unit (or group of multiplexers) that

enables the peripherals provided by the DAI to be intercon-

nected under software control. This allows easy use of the DAI

associated peripherals for a much wider variety of applications

by using a larger set of algorithms than is possible with noncon-

figurable signal paths.

The DAI includes eight serial ports, four precision clock genera-

tors (PCG), a S/PDIF transceiver, four ASRCs, and an input

data port (IDP). The IDP provides an additional input path to

the SHARC core, configurable as either eight channels of serial

data, or a single 20-bit wide synchronous parallel data acquisi-

tion port. Each data channel has its own DMA channel that is

independent from the processor’s serial ports.

Serial Ports (SPORTs)

The ADSP-2148x features eight synchronous serial ports that

provide an inexpensive interface to a wide variety of digital and

mixed-signal peripheral devices such as Analog Devices’

AD183x family of audio codecs, ADCs, and DACs. The serial

ports are made up of two data lines, a clock, and frame sync. The

data lines can be programmed to either transmit or receive and

each data line has a dedicated DMA channel.

Serial ports can support up to 16 transmit or 16 receive DMA

channels of audio data when all eight SPORTs are enabled, or

four full duplex TDM streams of 128 channels per frame.

Serial port data can be automatically transferred to and from

on-chip memory/external memory via dedicated DMA chan-

nels. Each of the serial ports can work in conjunction with

another serial port to provide TDM support. One SPORT pro-

vides two transmit signals while the other SPORT provides the

two receive signals. The frame sync and clock are shared.

Serial ports operate in five modes:

• Standard serial mode

•Multichannel (TDM) mode

•I

S mode

•Packed I

S mode

• Left-justified mode

S/PDIF-Compatible Digital Audio Receiver/Transmitter

The S/PDIF receiver/transmitter has no separate DMA chan-

nels. It receives audio data in serial format and converts it

into a biphase encoded signal. The serial data input to the

receiver/transmitter can be formatted as left-justified, I

S or

right-justified with word widths of 16, 18, 20, or 24 bits.

The serial data, clock, and frame sync inputs to the S/PDIF

receiver/transmitter are routed through the signal routing unit

(SRU). They can come from a variety of sources, such as the

SPORTs, external pins, or the precision clock generators

(PCGs), and are controlled by the SRU control registers.

Asynchronous Sample Rate Converter (SRC)

The asynchronous sample rate converter contains four SRC

blocks and is the same core as that used in the AD1896 192 kHz

stereo asynchronous sample rate converter and provides up to

128 dB SNR. The SRC block is used to perform synchronous or

asynchronous sample rate conversion across independent stereo

channels, without using internal processor resources. The four

SRC blocks can also be configured to operate together to

convert multichannel audio data without phase mismatches.

Finally, the SRC can be used to clean up audio data from jittery

clock sources such as the S/PDIF receiver.

Input Data Port

The IDP provides up to eight serial input channels—each with

its own clock, frame sync, and data inputs. The eight channels

are automatically multiplexed into a single 32-bit by eight-deep

FIFO. Data is always formatted as a 64-bit frame and divided

into two 32-bit words. The serial protocol is designed to receive

audio channels in I

S, left-justified sample pair, or right-justified

mode.

The IDP also provides a parallel data acquisition port (PDAP),

which can be used for receiving parallel data. The PDAP port

has a clock input and a hold input. The data for the PDAP can

be received from DAI pins or from the external port pins. The

PDAP supports a maximum of 20-bit data and four different

packing modes to receive the incoming data.

Precision Clock Generators

The precision clock generators (PCG) consist of four units, each

of which generates a pair of signals (clock and frame sync)

derived from a clock input signal. The units, A B, C, and D, are

identical in functionality and operate independently of each

other. The two signals generated by each unit are normally used

as a serial bit clock/frame sync pair.

Rev. E | Page 10 of 68 | June 2017

ADSP-21483/ADSP-21486/ADSP-21487/ADSP-21488/ADSP-21489

The outputs of PCG A and B can be routed through the DAI

pins and the outputs of PCG C and D can be driven on to the

DAI as well as the DPI pins.

Digital Peripheral Interface (DPI)

The ADSP-2148x SHARC processors have a digital peripheral

interface that provides connections to two serial peripheral

interface ports (SPI), one universal asynchronous receiver-

transmitter (UART), 12 flags, a 2-wire interface (TWI), three

PWM modules (PWM3–1), and two general-purpose timers.

Serial Peripheral (Compatible) Interface (SPI)

The SPI is an industry-standard synchronous serial link,

enabling the SPI-compatible port to communicate with other

SPI compatible devices. The SPI consists of two data pins, one

device select pin, and one clock pin. It is a full-duplex synchro-

nous serial interface, supporting both master and slave modes.

The SPI port can operate in a multimaster environment by

interfacing with up to four other SPI-compatible devices, either

acting as a master or slave device. The SPI-compatible periph-

eral implementation also features programmable baud rate and

clock phase and polarities. The SPI-compatible port uses open

drain drivers to support a multimaster configuration and to

avoid data contention.

UART Port

The processors provide a full-duplex Universal Asynchronous

Receiver/Transmitter (UART) port, which is fully compatible

with PC-standard UARTs. The UART port provides a simpli-

fied UART interface to other peripherals or hosts, supporting

full-duplex, DMA-supported, asynchronous transfers of serial

data. The UART also has multiprocessor communication capa-

bility using 9-bit address detection. This allows it to be used in

multidrop networks through the RS-485 data interface

standard. The UART port also includes support for 5 to 8 data

bits, 1 or 2 stop bits, and none, even, or odd parity. The UART

port supports two modes of operation:

• PIO (programmed I/O)—The processor sends or receives

data by writing or reading I/O-mapped UART registers.

The data is double-buffered on both transmit and receive.

• DMA (direct memory access)—The DMA controller trans-

fers both transmit and receive data. This reduces the

number and frequency of interrupts required to transfer

data to and from memory. The UART has two dedicated

DMA channels, one for transmit and one for receive. These

DMA channels have lower default priority than most DMA

channels because of their relatively low service rates.

Timers

The ADSP-2148x has a total of three timers: a core timer that

can generate periodic software interrupts and two general-

purpose timers that can generate periodic interrupts and be

independently set to operate in one of three modes:

• Pulse waveform generation mode

• Pulse width count/capture mode

• External event watchdog mode

The core timer can be configured to use FLAG3 as a timer

expired signal, and the general-purpose timers have one bidirec-

tional pin and four registers that implement its mode of

operation: a 6-bit configuration register, a 32-bit count register,

a 32-bit period register, and a 32-bit pulse width register. A sin-

gle control and status register enables or disables the general-

purpose timer.

2-Wire Interface Port (TWI)

The TWI is a bidirectional 2-wire, serial bus used to move 8-bit

data while maintaining compliance with the I

C bus protocol.

The TWI master incorporates the following features:

• 7-bit addressing

• Simultaneous master and slave operation on multiple

device systems with support for multi master data

arbitration

• Digital filtering and timed event processing

• 100 kbps and 400 kbps data rates

• Low interrupt rate

I/O PROCESSOR FEATURES

The I/O processors provide up to 65 channels of DMA, as well

as an extensive set of peripherals.

DMA Controller

The processor’s on-chip DMA controller allows data transfers

without processor intervention. The DMA controller operates

independently and invisibly to the processor core, allowing

DMA operations to occur while the core is simultaneously exe-

cuting its program instructions. DMA transfers can occur

between the ADSP-2148x’s internal memory and its serial ports,

the SPI-compatible (serial peripheral interface) ports, the IDP

(input data port), the PDAP, or the UART. The DMA channel

summary is shown in Table 8.

Programs can be downloaded to the ADSP-2148x using DMA

transfers. Other DMA features include interrupt generation

upon completion of DMA transfers and DMA chaining for

automatic linked DMA transfers.

Rev. E | Page 11 of 68 | June 2017

Delay Line DMA

The processor provides delay line DMA functionality. This

allows processor reads and writes to external delay line buffers

(and hence to external memory) with limited core interaction.

Scatter/Gather DMA

The processor provides scatter/gather DMA functionality. This

allows processor DMA reads/writes to/from non contiguous

memory blocks.

FFT Accelerator

The FFT accelerator implements a radix-2 complex/real input,

complex output FFT with no core intervention. The FFT accel-

erator runs at the peripheral clock frequency.

FIR Accelerator

The FIR (finite impulse response) accelerator consists of a 1024

word coefficient memory, a 1024 word deep delay line for the

data, and four MAC units. A controller manages the accelerator.

The FIR accelerator runs at the peripheral clock frequency.

IIR Accelerator

The IIR (infinite impulse response) accelerator consists of a

1440 word coefficient memory for storage of biquad coeffi-

cients, a data memory for storing the intermediate data, and one

MAC unit. A controller manages the accelerator. The IIR accel-

erator runs at the peripheral clock frequency.

Watchdog Timer

The watchdog timer is used to supervise the stability of the sys-

tem software. When used in this way, software reloads the

watchdog timer in a regular manner so that the downward

counting timer never expires. An expiring timer then indicates

that system software might be out of control.

The 32-bit watchdog timer that can be used to implement a soft-

ware watchdog function. A software watchdog can improve

system reliability by forcing the processor to a known state

through generation of a system reset, if the timer expires before

being reloaded by software. Software initializes the count value

of the timer, and then enables the timer. The watchdog timer

resets both the core and the internal peripherals. Note that this

feature is available on the 176-lead package only.

SYSTEM DESIGN

The following sections provide an introduction to system design

options and power supply issues.

Program Booting

The internal memory of the ADSP-2148x boots at system

power-up from an 8-bit EPROM via the external port, an SPI

master, or an SPI slave. Booting is determined by the boot con-

figuration (BOOT_CFG2–0) pins in Table 9 for the 176-lead

package and Table 10 for the 100-lead package.

The “Running Reset” feature allows a user to perform a reset of

the processor core and peripherals, but without resetting the

PLL and SDRAM controller, or performing a boot. The

functionality of the RESETOUT/RUNRSTIN pin has now been

extended to also act as the input for initiating a Running Reset.

For more information, see the hardware reference manual.

Power Supplies

The processors have separate power supply connections for the

internal (V

DD_INT

) and external (V

DD_EXT

) power supplies. The

internal supply must meet the V

DD_INT

specifications. The

external supply must meet the V

DD_EXT

specification. All exter-

nal supply pins must be connected to the same power supply.

To reduce noise coupling, the PCB should use a parallel pair of

power and ground planes for V

DD_INT

and GND.

Static Voltage Scaling (SVS)

Some models of the ADSP-2148x feature Static Voltage Scaling

(SVS) on the V

DD_INT

power supply. (See the Ordering Guide

on Page 66 for model details.) This voltage specification tech-

nique can provide significant performance benefits including

450 MHz core frequency operation without a significant

increase in power.

SVS optimizes the required V

DD_INT

voltage for each individual

device to enable enhanced operating frequency up to 450 MHz.

The optimized SVS voltage results in a reduction of maximum

DD_INT

which enables 450 MHz operation at the same or lower

maximum power than 400 MHz operation at a fixed voltage

supply. Implementation of SVS requires a specific voltage regu-

lator circuit design and initialization code.

Refer to the Engineer-to-Engineer Note Static Voltage Scaling

for ADSP-2148x SHARC Processors (EE-357) for further infor-

mation. The EE-Note details the requirements and process to

implement a SVS power supply system to enable operation up

to 450 MHz. This applies only to specific products within the

ADSP-2148x family which are capable of supporting 450 MHz

operation.

Details on power consumption and Static and Dynamic current

consumption can be found at Total Power Dissipation on

Page 20. Also see Operating Conditions on Page 18 for more

information.

The following are SVS features.

• SVS is applicable only to 450 MHz models (not applicable

to 400 MHz or lower frequency models).

• Each individual SVS device includes a register (SVS_DAT)

containing the unique SVS voltage set at the factory, known

as SVS

NOM

•The SVS

NOM

value is the intended set voltage for the

DD_INT

voltage regulator.

• No dedicated pins are required for SVS. The TWI serial bus

is used to communicate SVS

NOM

to the voltage regulator.

• Analog Devices recommends a specific voltage regulator

design and initialization code sequence that optimizes the

power-up sequence.

The Engineer-to-Engineer Note Static Voltage Scaling for

ADSP-2148x SHARC Processors (EE-357) contains the

details of the regulator design and the initialization

requirements.

• Any differences from the Analog Devices recommended

programmable regulator design must be reviewed by Ana-

log Devices to ensure that it meets the voltage accuracy and

range requirements.

Target Board JTAG Emulator Connector

Analog Devices DSP Tools product line of JTAG emulators uses

the IEEE 1149.1 JTAG test access port of the ADSP-2148x pro-

cessors to monitor and control the target board processor

during emulation. Analog Devices DSP Tools product line of

JTAG emulators provides emulation at full processor speed,

allowing inspection and modification of memory, registers, and

processor stacks. The processor’s JTAG interface ensures that

the emulator will not affect target system loading or timing.

For complete information on Analog Devices’ SHARC DSP

Tools product line of JTAG emulator operation, see the appro-

priate emulator hardware user’s guide.

DEVELOPMENT TOOLS

Analog Devices supports its processors with a complete line of

software and hardware development tools, including integrated

development environments (which include CrossCore

Embed-

ded Studio and/or VisualDSP++

), evaluation products,

emulators, and a wide variety of software add-ins.

Integrated Development Environments (IDEs)

For C/C++ software writing and editing, code generation, and

debug support, Analog Devices offers two IDEs.

Designing an Emulator-Compatible DSP Board (Target)

For embedded system test and debug, Analog Devices provides

a family of emulators. On each JTAG DSP, Analog Devices sup-

plies an IEEE 1149.1 JTAG Test Access Port (TAP). In-circuit

emulation is facilitated by use of this JTAG interface. The emu-

lator accesses the processor’s internal features via the

processor’s TAP, allowing the developer to load code, set break-

points, and view variables, memory, and registers. The

processor must be halted to send data and commands, but once

an operation is completed by the emulator, the DSP system is set

to run at full speed with no impact on system timing. The emu-

lators require the target board to include a header that supports

connection of the DSP’s JTAG port to the emulator.

For details on target board design issues including mechanical

layout, single processor connections, signal buffering, signal ter-

mination, and emulator pod logic, see Analog Devices JTAG

Emulation Technical Reference (EE-68). This document is

updated regularly to keep pace with improvements to emulator

support.

RELATED SIGNAL CHAINS

A signal chain is a series of signal-conditioning electronic com-

ponents that receive input (data acquired from sampling either

real-time phenomena or from stored data) in tandem, with the

output of one portion of the chain supplying input to the next.

Signal chains are often used in signal processing applications to

gather and process data or to apply system controls based on

analysis of real-time phenomena.

Analog Devices eases signal processing system development by

providing signal processing components that are designed to

work together well. A tool for viewing relationships between

specific applications and related components is available on the

www.analog.com website.

The application signal chains page in the Circuits from the Lab

site (http:\\www.analog.com\circuits) provides:

• Graphical circuit block diagram presentation of signal

chains for a variety of circuit types and applications

• Drill down links for components in each chain to selection

guides and application information

• Reference designs applying best practice design techniques

(boot)

External Address. The processor outputs addresses for external memory and periph-

erals on these pins. The ADDR pins can be multiplexed to support the external memory

interface address, and FLAGS15–8 (I/O) and PWM (O). After reset, all ADDR pins are in

external memory interface mode and FLAG(0–3) pins are in FLAGS mode (default).

When configured in the IDP_PDAP_CTL register, IDP channel 0 scans the ADDR

23–4

pins

for parallel input data.

I/O/T (ipu) High-Z External Data. The data pins can be multiplexed to support the external memory

interface data (I/O), and FLAGS

7–0

(I/O).

AMI_ACK I (ipu) Memory Acknowledge. External devices can deassert AMI_ACK (low) to add wait

states to an external memory access. AMI_ACK is used by I/O devices, memory

controllers, or other peripherals to hold off completion of an external memory access.

0–1

O/T (ipu) High-Z Memory Select Lines 0–1. These lines are asserted (low) as chip selects for the corre-

sponding banks of external memory. The MS

1-0

lines are decoded memory address lines

that change at the same time as the other address lines. When no external memory

access is occurring the MS

1-0

lines are inactive; they are active however when a condi-

tional memory access instruction is executed, when the condition evaluates as true.

The MS1 pin can be used in EPORT/FLASH boot mode. For more information, see the

hardware reference manual.

AMI_RD O/T (ipu) High-Z AMI Port Read Enable. AMI_RD is asserted whenever the processor reads a word from

external memory.

AMI_WR O/T (ipu) High-Z AMI Port Write Enable. AMI_WR is asserted when the processor writes a word to

external memory.

The following symbols appear in the Type column of this table: A = asynchronous, I= input, O = output, S = synchronous, A/D = active drive,

O/D = open drain, and T = three-state, ipd = internal pull-down resistor, ipu = internal pull-up resistor.

The internal pull-up (ipu) and internal pull-down (ipd) resistors are designed to hold the internal path from the pins at the expected logic

levels. To pull-up or pull-down the external pads to the expected logic levels, use external resistors. Internal pull-up/pull-down resistors cannot

be enabled/disabled and the value of these resistors cannot be programmed. The range of an ipu resistor can be between 26 kΩ–63 kΩ. The

range of an ipd resistor can be between 31 kΩ–85kΩ. The three-state voltage of ipu pads will not reach to the full V

DD_EXT

level; at typical

conditions the voltage is in the range of 2.3 V to 2.7 V.

In this table, all pins are LVTTL compliant with the exception of the thermal diode pins.

during a read cycle. SDDQM is driven high from reset de-assertion until SDRAM initial-

ization completes. Afterwards it is driven low irrespective of whether any SDRAM

accesses occur or not.

SRU. The DAI SRU configuration registers define the combination of on-chip audio-

centric peripheral inputs or outputs connected to the pin and to the pin’s output enable.

ICore to CLKIN Ratio Control. These pins set the start up clock frequency.

Note that the operating frequency can be changed by programming the PLL multiplier

and divider in the PMCTL register at any time after the core comes out of reset. The

allowed values are:

00 = 8:1

01 = 32:1

CLKIN I Local Clock In. Used in conjunction with XTAL. CLKIN is the clock input. It configures

the processors to use either its internal clock generator or an external clock source.

Connecting the necessary components to CLKIN and XTAL enables the internal clock

generator. Connecting the external clock to CLKIN while leaving XTAL unconnected

configures the processors to use the external clock source such as an external clock

oscillator. CLKIN may not be halted, changed, or operated below the specified

frequency.

XTAL O Crystal Oscillator Terminal. Used in conjunction with CLKIN to drive an external

crystal.

RESET IProcessor Reset. Resets the processor to a known state. Upon deassertion, there is a

4096 CLKIN cycle latency for the PLL to lock. After this time, the core begins program

execution from the hardware reset vector address. The RESET input must be asserted

(low) at power-up.

RESETOUT/

RUNRSTIN

I/O (ipu) Reset Out/Running Reset In. The default setting on this pin is reset out. This pin also

has a second function as RUNRSTIN which is enabled by setting bit 0 of the RUNRSTCTL

BOOT_CFG

Total Power Dissipation

The information in this section should be augmented with the

Engineer-to-Engineer Note Estimating Power for ADSP-214xx

SHARC Processors (EE-348).

Total power dissipation has two components:

1. Internal power consumption is additionally comprised of

two components:

• Static current due to leakage. Table 14 shows the static

current consumption (I

DD_INT_STATIC

) as a function of

junction temperature (T

) and core voltage (V

DD_INT

• Dynamic current (I

DD_INT_DYNAMIC

), due to transistor

switching characteristics and activity level of the pro-

cessor. The activity level is reflected by the Activity

Scaling Factor (ASF), which represents the activity

level of the application code running on the processor

core and having various levels of peripheral and exter-

nal port activity (Table 13).

Dynamic current consumption is calculated by select-

ing the ASF that corresponds most closely with the

user application and then multiplying that with the

dynamic current consumption (Table 15).

2. External power consumption is due to the switching activ-

ity of the external pins.

TIMING SPECIFICATIONS

Use the exact timing information given. Do not attempt to

derive parameters from the addition or subtraction of others.

While addition or subtraction would yield meaningful results

for an individual device, the values given in this data sheet

reflect statistical variations and worst cases. Consequently, it is

not meaningful to add parameters to derive longer times. See

Figure 43 on Page 55 for voltage reference levels.

Switching characteristics specify how the processor changes its

signals. Circuitry external to the processor must be designed for

compatibility with these signal characteristics. Switching char-

acteristics describe what the processor will do in a given

circumstance. Use switching characteristics to ensure that any

timing requirement of a device connected to the processor (such

as memory) is satisfied.

Timing requirements apply to signals that are controlled by cir-

cuitry external to the processor, such as the data input for a read

operation. Timing requirements guarantee that the processor

operates correctly with other devices.

Core Clock Requirements

The processor’s internal clock (a multiple of CLKIN) provides

the clock signal for timing internal memory, the processor core,

and the serial ports. During reset, program the ratio between the

processor’s internal clock frequency and external (CLKIN)

clock frequency with the CLK_CFG1–0 pins.

The processor’s internal clock switches at higher frequencies

than the system input clock (CLKIN). To generate the internal

clock, the processor uses an internal phase-locked loop (PLL,

see Figure 4). This PLL-based clocking minimizes the skew

between the system clock (CLKIN) signal and the processor’s

internal clock.

Voltage Controlled Oscillator (VCO)

In application designs, the PLL multiplier value should be

selected in such a way that the VCO frequency never exceeds

VCO

specified in Table 20.

• The product of CLKIN and PLLM must never exceed 1/2 of

VCO

(max) in Table 20 if the input divider is not enabled

(INDIV = 0).

• The product of CLKIN and PLLM must never exceed f

VCO

(max) in Table 20 if the input divider is enabled

(INDIV = 1).

The VCO frequency is calculated as follows:

VCO

= 2 × PLLM × f

INPUT

CCLK

= (2 × PLLM × f

INPUT

) ÷ PLLD

where:

VCO

= VCO output

PLLM = Multiplier value programmed in the PMCTL register.

During reset, the PLLM value is derived from the ratio selected

using the CLK_CFG pins in hardware.

PLLD = 2, 4, 8, or 16 based on the divider value programmed on

the PMCTL register. During reset this value is 2.

INPUT

= is the input frequency to the PLL.

INPUT

= CLKIN when the input divider is disabled or

INPUT

= CLKIN ÷ 2 when the input divider is enabled

Note the definitions of the clock periods that are a function of

CLKIN and the appropriate ratio control shown in Table 18. All

of the timing specifications for the ADSP-2148x peripherals are

defined in relation to t

PCLK

. See the peripheral specific section

for each peripheral’s timing information.

Figure 4 shows core to CLKIN relationships with external oscil-

lator or crystal. The shaded divider/multiplier blocks denote

where clock ratios can be set through hardware or software

using the power management control register (PMCTL). For

more information, see the hardware reference manual.

Power-Up Sequencing

The timing requirements for processor startup are given in

Table 19. While no specific power-up sequencing is required

between V

DD_EXT

and V

DD_INT

, there are some considerations

that system designs should take into account.

• No power supply should be powered up for an extended

period of time (> 200 ms) before another supply starts to

ramp up.

•If the V

DD_INT

power supply comes up after V

DD_EXT

, any

pin, such as RESETOUT and RESET, may actually drive

momentarily until the V

DD_INT

rail has powered up.

Systems sharing these signals on the board must determine

if there are any issues that need to be addressed based on

this behavior.

Note that during power-up, when the V

DD_INT

power supply

comes up after V

DD_EXT

, a leakage current of the order of three-

state leakage current pull-up, pull-down may be observed on

any pin, even if that is an input only (for example the RESET

pin) until the V

DD_INT

rail has powered up.

assumes that the supplies are fully ramped to their nominal values (it does not matter which supply comes up first). Voltage ramp rates can vary

from microseconds to hundreds of milliseconds depending on the design of the power supply subsystem.

Assumes a stable CLKIN signal, after meeting worst-case startup timing of crystal oscillators. Refer to your crystal oscillator manufacturer's data sheet for startup time. Assume

a 25 ms maximum oscillator startup time if using the XTAL pin and internal oscillator circuit in conjunction with an external crystal.

Based on CLKIN cycles.

Applies after the power-up sequence is complete. Subsequent resets require a minimum of four CLKIN cycles for RESET to be held low in order to properly initialize and

propagate default states at all I/O pins.

The 4096 cycle count depends on t

SRST

specification in Table 21. If setup time is not met, one additional CLKIN cycle may be added to the core reset time, resulting in 4097

cycles maximum.

Clock Signals

The ADSP-2148x can use an external clock or a crystal. See the

CLKIN pin description in Table 11 on Page 14. Programs can

configure the processor to use its internal clock generator by

connecting the necessary components to CLKIN and XTAL.

Figure 7 shows the component connections used for a crystal

operating in fundamental mode. Note that the clock rate is

achieved using a 25 MHz crystal and a PLL multiplier ratio 16:1

(CCLK:CLKIN achieves a clock speed of 400 MHz). To achieve

the full core clock rate, programs need to configure the multi-

plier bits in the PMCTL register.

Serial Ports

In slave transmitter mode and master receiver mode, the maxi-

mum serial port frequency is f

PCLK

/8. In master transmitter

mode and slave receiver mode, the maximum serial port clock

frequency is f

PCLK

/4. To determine whether communication is

possible between two devices at clock speed n, the following

specifications must be confirmed: 1) frame sync delay and frame

sync setup and hold; 2) data delay and data setup and hold; and

3) SCLK width.

Serial port signals (SCLK, frame sync, Data Channel A, Data

Channel B) are routed to the DAI_P20–1 pins using the SRU.

Therefore, the timing specifications provided below are valid at

the DAI_P20–1 pins.

Pulse-Width Modulation Generators (PWM)

The following timing specifications apply when the

ADDR23–8/DPI_14–1 pins are configured as PWM.

S/PDIF Transmitter

Serial data input to the S/PDIF transmitter can be formatted as

left-justified, I

S, or right-justified with word widths of 16, 18,

20, or 24 bits. The following sections provide timing for the

transmitter.

S/PDIF Transmitter-Serial Input Waveforms

Figure 30 shows the right-justified mode. Frame sync is high for

the left channel and low for the right channel. Data is valid on

the rising edge of serial clock. The MSB is delayed the minimum

in 24-bit output mode or the maximum in 16-bit output mode

from a frame sync transition, so that when there are 64 serial

clock periods per frame sync period, the LSB of the data is right-

justified to the next frame sync transition.

Pulse width variation is measured at 1.25 V by triggering on one edge of MLBCLK and measuring the spread on the other edge, measured in ns peak-to-peak (pp).

The board must be designed to ensure that the high-impedance bus does not leave the logic state of the final driven bit for this time period. Therefore, coupling must be

minimized while meeting the maximum capacitive load listed.

Pulse width variation is measured at 1.25 V by triggering on one edge of MLBCLK and measuring the spread on the other edge, measured in ns peak-to-peak (pp).

Gate Delays due to OR'ing logic on the pins must be accounted for.

When a node is not driving valid data onto the bus, the MLBSO and MLBDO output lines shall remain low. If the output lines can float at anytime, including while in reset,

external pull-down resistors are required to keep the outputs from corrupting the MediaLB signal lines when not being driven.

OUTPUT DRIVE CURRENTS

Figure 41 shows typical I-V characteristics for the output driv-

ers of the ADSP-2148x, and Table 55 shows the pins associated

with each driver. The curves represent the current drive capabil-

ity of the output drivers as a function of output voltage.

TEST CONDITIONS

The ac signal specifications (timing parameters) appear in

Table 21 on Page 26 through Table 54 on Page 54. These include

output disable time, output enable time, and capacitive loading.

The timing specifications for the SHARC apply for the voltage

reference levels in Figure 42.

Timing is measured on signals when they cross the 1.5 V level as

described in Figure 43. All delays (in nanoseconds) are mea-

sured between the point that the first signal reaches 1.5 V and

the point that the second signal reaches 1.5 V.

CAPACITIVE LOADING

Output delays and holds are based on standard capacitive loads:

30 pF on all pins (see Figure 42). Figure 46 and Figure 47 show

graphically how output delays and holds vary with load capaci-

tance. The graphs of Figure 44 through Figure 47 may not be

linear outside the ranges shown for Typical Output Delay vs.

Load Capacitance and Typical Output Rise Time (20% to 80%,

V = Min) vs. Load Capacitance.

Note that the thermal characteristics values provided in

Table 56 and Table 57 are modeled values.

Thermal Diode

The ADSP-2148x processors incorporate thermal diode/s to

monitor the die temperature. The thermal diode of is a

grounded collector, PNP Bipolar Junction Transistor (BJT). The

THD_P pin is connected to the emitter and the THD_M pin is

connected to the base of the transistor. These pins can be used

by an external temperature sensor (such as ADM 1021A or

LM86 or others) to read the die temperature of the chip.

The technique used by the external temperature sensor is to

measure the change in VBE when the thermal diode is operated

at two different currents. This is shown in the following

equation:

where:

n = multiplication factor close to 1, depending on process

variations

k = Boltzmann’s constant

T = temperature (°C)

q = charge of the electron

N = ratio of the two currents

The two currents are usually in the range of 10 micro Amperes

to 300 micro Amperes for the common temperature sensor

chips available.

Table 58 contains the thermal diode specifications using the

transistor model.

SURFACE-MOUNT DESIGN

The exposed pad is required to be electrically and thermally

connected to GND. Implement this by soldering the exposed

pad to a GND PCB land that is the same size as the exposed pad.

The GND PCB land should be robustly connected to the GND

plane in the PCB for best electrical and thermal performance.

No separate GND pins are provided in the package.
