IDT7007S/L
HIGH-SPEED 32K x 8 DUAL-PORT STATIC RAM MILITARY AND COMMERCIAL TEMPERATURE RANGES

DESCRIPTION:

The IDT7007 is a high-speed 32K x 8 Dual-Port Static
RAM. The IDT7007 is designed to be used as a stand-alone
256K-bit Dual-Port RAM or as a combination MASTER/
SLAVE Dual-Port RAM for 16-bit-or-more word systems.
Using the IDT MASTER/SLAVE Dual-Port RAM approach in
16-bit or wider memory system applications results in full­speed, error-free operation without the need for additional
discrete logic.

This device provides two independent ports with separate
control, address, and I/O pins that permit independent,
asynchronous access for reads or writes to any location in

memory. An automatic power down feature controlled by
permits the on-chip circuitry of each port to enter a very low
standby power mode.

Fabricated using IDT’s CMOS high-performance technol-

ogy, these devices typically operate on only 750mW of power.

The IDT7007 is packaged in a 68-pin pin PGA, a 68-pin
PLCC, and a 80-pin TQFP (thin plastic quad flatpack). 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.
