IDT7187L General Description
The IDT7187 is a 65,536-bit high-speed static RAM organized as 64K x 1. It is fabricated using IDT's highperformance, 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-ISB and ISB1. ISB provides low-power operation; ISB1 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 30mW.
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.
