DESCRIPTION:

The IDT7187 is a 65,536-bit high-speed static RAM

organized as 64K x 1. It is fabricated using IDT’s high-

performance, high-reliability CMOS technology. Access times

as fast as 25ns are available.

Both the standard (S) and low-power (L) versions of the

operation. The low-power (L) version also provides the capa-

bility for data retention using battery backup. When using a 2V

battery, the circuit typically consumes only 30

µW.

Ease of system design is achieved by the IDT7187 with full

asynchronous operation, along with matching access and

cycle times. The device is packaged in an industry standard

22-pin, 300 mil ceramic DIP, or 22-pin leadless chip carriers.

Military grade product 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.
