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

IDT7008isdesignedtobeusedasastand-alone512K-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, 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 (

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).
