Functional Description
The CY62167EV18 is a high performance CMOS static RAM
organized as 1M words by 16 bits. This device features
advanced circuit design to provide ultra low active current. This
is ideal for providing More Battery Life (MoBL®) in portable
applications such as cellular telephones. The device also has an
automatic power down feature that reduces power consumption
by 99 percent when addresses are not toggling. Place the device
into standby mode when deselected (CE1 HIGH or CE2 LOW or
both BHE and BLE are HIGH). The input and output pins (I/O0
through I/O15) are placed in a high impedance state when: the
device is deselected (CE1HIGH or CE2 LOW); outputs are
disabled (OE HIGH); both Byte High Enable and Byte Low
Enable are disabled (BHE, BLE HIGH); and a write operation is
in progress (CE1 LOW, CE2 HIGH and WE LOW).
To write to the device, take Chip Enables (CE1 LOW and CE2
HIGH) and Write Enable (WE) input LOW. If Byte Low Enable
(BLE) is LOW, then data from I/O pins (I/O0 through I/O7) is
written into the location specified on the address pins (A0 through
A19). If Byte High Enable (BHE) is LOW, then data from I/O pins
(I/O8 through I/O15) is written into the location specified on the
address pins (A0 through A19).
To read from the device, take Chip Enables (CE1 LOW and CE2
HIGH) and Output Enable (OE) LOW while forcing the Write
Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data
from the memory location specified by the address pins appears
on I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from
memory appears on I/O8 to I/O15. See the Truth Table on page
9 for a complete description of read and write modes.
For best practice recommendations, refer to the Cypress
application note AN1064, SRAM System Guidelines.

Notes
13. Test conditions for all parameters other than tri-state parameters are based on signal transition time of 1V/ns, timing reference levels of VCC(typ)/2, input pulse levels
of 0 to VCC(typ), and output loading of the specified IOL/IOH as shown in AC Test Loads and Waveforms on page 4.
14. AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. See application note AN13842 for further clarification.
15. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given
device.
16. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the output enters a high impedance state.
17. The internal memory write time is defined by the overlap of WE, CE1 = VIL, BHE and/or BLE = VIL, and CE2 = VIH. All signals must be ACTIVE to initiate a write and
any of these signals can terminate a write by going INACTIVE. The data input setup and hold timing must be referenced to the edge of the signal that terminates the write.
