IDT71256S
IDT71256L
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
CS
goes HIGH, the circuit will automatically go to and
remain in, a low-power standby mode as long as
CS
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.
