It is fabricated using 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 CS goes HIGH, the circuit will automatically go to and
remain in, a low-power standby mode as long as CS remains HIGH. 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 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
