CMOS STATIC RAM

256K (32K x 8-BIT)

Integrated Device Technology, Inc.

FEATURES:

• High-speed address/chip select time

DESCRIPTION:

— Military: 25/30/35/45/55/70/85/100/120/150ns (max.)

— Commercial: 20/25/35/45ns (max.) Low Power only.

• Low-power operation

The IDT71256 is a 262,144-bit high-speed static RAM

organized as 32K x 8. It is fabricated using IDT’s high-

performance, high-reliability CMOS technology.

• Battery Backup operation — 2V data retention

• Produced with advanced high-performance CMOS

technology

• Input and output directly TTL-compatible

• Available in standard 28-pin (300 or 600 mil) ceramic

DIP, 28-pin (600 mil) plastic DIP, 28-pin (300 mil) SOJ

and 32-pin LCC

Address access times as fast as 20ns are available with

power consumption of only 350mW (typ.). The circuit also

offers a reduced power standby mode. When CSgoes HIGH,

the circuit will automatically go to, and remain in, a low-power

standbymodeaslongasCSremainsHIGH. Inthefullstandby

mode, the low-power device consumes less than 15µW,

typically. This capability provides significant system level

power and cooling savings. The low-power (L) version also

offers a battery backup data retention capability where the

circuit typically consumes only 5µW when operating off a 2V

battery.

• Military product compliant to MIL-STD-883, Class B

The lDT71256 is packaged in a 28-pin (300 or 600 mil)

ceramic DIP, a 28-pin 300 mil J-bend SOlC, and a 28-pin (600

mil) plastic DIP, and 32-pin LCC providing high board-level

packing densities.

TheIDT71256militaryRAMismanufacturedincompliance

with the latest revision of MIL-STD-883, Class B, making it

ideally suited to military temperature applications demanding

the highest level of performance and reliability.
