DESCRIPTION:
The IDT7187 is a 65,536-bit high-speed static RAM
organized as 64K x 1. It is fabricated using IDT鈥檚 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
IDT7187 provide two standby modes鈥擨
SB
and I
SB1
. I
SB
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 30碌W.
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.
