Description

The IDT 71256 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.

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

goes HIGH, the circuit will automatically go to and

remain in, a low-power standby mode as long as

remains HIGH. In

the full standby 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.

The IDT71256 is packaged in a 28-pin (300 or 600 mil) ceramic DIP,

a 28-pin 300 mil SOJ, a 28-pin (600 mil) plastic DIP, and a 32-pin LCC

providing high board level packing densities.

The IDT71256 military RAM is manufactured in compliance 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.
