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 capability 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 ceramic
DIP.
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.
