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 25ns are available.
Both the standard (S) and low-power (L) versions of the
IDT7187 provide two standby modes—I
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
μ
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.
