Military product compliant to MIL-STD-883, Class B
DESCRIPTION:
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.
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 15
μ
W,
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 5
μ
W when operating off a 2V
battery.
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.
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.
