TOSHIBA TC551001CP/CF/CFT/CTR/CST/CSR-55,-70,-85,-55L,-70L,-85L TENTATIVE TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS 131,072-WORD BY 8-BIT STATIC RAM DESCRIPTION The TC551001CP/CF/CFT/CTR/CST/CSR is a 1,048,576-bit static random access memory (SRAM) organized as 131,072 words by 8 bits. Fabricated using Toshibas CMOS Silicon gate process technology, this device operates from a single 5 V + 10% power supply. Advanced circuit technology provides both high speed and low power at an operating current of 5mA/MHz (typ) and a minimum cycle time of 55 ns. It is automatically placed in low-power mode at 1 4A standby current (typ) when chip enable (CE1) is asserted high or (CE2) is asserted low. There are three control inputs. CH1 and CE2 are used to select the device and for data retention control, and output enable (OE) provides fast memory access. This device is well suited to various microprocessor system applications where high speed, low power and battery backup are required. The TC551001CP/CF/ CFT/CTR/CST/CSR is available in a standard plastic 32-pin dual-in-line package (DIP), plastic 32-pin small- outline package (SOP) and normal and reverse pinout plastic 32-pin thin-small-outline package (TSOP).

(2) If CE] goes LOW (or CE2 goes HIGH) coincident with or after R/W goes LOW, the outputs will remain at high impedance. (3) If CE1 goes HIGH (or CE2 goes LOW) coincident with or before R/W goes HIGH, the outputs will remain at high impedance. (4) If OF is HIGH during the write cycle, the outputs will remain at high impedance. (5) Because I/O signals may be in the output state at this time, input signals of reverse polarity must not be applied.
