Integrated Device Technology 

IDT7008S/L

High-Speed 64K x 8 Dual-Port Static RAM

Military, Industrial and Commercial Temperature Ranges

Description

The IDT7008 is a high-speed 64K x 8 Dual-Port Static RAM. The

IDT7008 is designed to be used as a stand-alone 512K-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 full-speed, 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 the chip enables (CE0 and CE1) permit 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 750mW of power.

The IDT7008 is packaged in a 84-pin Ceramic Pin Grid Array (PGA),

a 84-pin Plastic Leadless Chip Carrier (PLCC) and a 100-pin Thin Quad

Flatpack (TQFP).
