CMOS STATIC RAM

64K (64K x 1-BIT)

Integrated Device Technology, Inc.

IDT7187S

IDT7187L

FEATURES:

• High speed (equal access and cycle time)

— Military: 20/25/35/45/55/70/85ns (max.)

— Commercial: 15/20/25ns (max.)

• Low power consumption

• Battery backup operation—2V data retention (L version

only)

• JEDEC standard high-density 22-pin plastic and ceramic

DIP, 22-pin and 28-pin leadless chip carrier and 24-pin

CERPACK

• Produced with advanced CMOS high-performance

technology

• Separate data input and output

• Input and output directly TTL-compatible

• Military product compliant to MIL-STD-883, Class B

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 15ns are available.

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

IDT7187 provide two standby modes—I

and I

SB1

. I

provides low-power operation; I

SB1

provides ultra-low-power

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 30µW.

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 plastic or ceramic DIP, 22- and 28-pin leadless

chip carriers, or 24-pin CERPACK.

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.
