IDT7007S/L
High-Speed 32K x 8 Dual-Port Static RAM	Military, Industrial and Commercial Temperature Ranges

Description

The IDT7007 is a high-speed 32K x 8 Dual-Port Static RAM. The IDT7007isdesignedtobeusedasastand-alone256K-bitDual-PortRAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more wordsystems.UsingtheIDTMASTER/SLAVEDual-PortRAMapproach in 16-bit or wider memory system applications results in full-speed, errorfree 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 CE permits the on-chip circuitry of each port to enter a very LOW standby power mode.

Fabricated using IDT’s CMOS high-performance technology, these devices typically operate on only 850mW of power.

The IDT7007 is packaged in a 68-pin pin PGA, a 68-pin PLCC, and an 80-pin thin quad flatpack, TQFP. Military grade product is manufactured in compliance with the latest revision of MIL-PRF-38535 QML,ClassB,makingitideallysuitedtomilitarytemperatureapplications demanding the highest level of performance and reliability.
