IDT7027S/L

High-Speed 32K x 16 Dual-Port Static RAM

Military, Industrial and Commercial Temperature Ranges

Description

The IDT7027 is a high-speed 32K x 16 Dual-Port Static RAM,

designed to be used as a stand-alone 512K-bit Dual-Port RAM or as a

combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word

systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-

bit or wider memory system applications results in full-speed, error-free

operation without the need for additional discrete logic.

The 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) 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 750mW of power. The IDT7027 is

packaged in a 100-pin Thin Quad Flatpack (TQFP) and a 108-pin ceramic

Pin Grid Array (PGA).

Military grade product is manufactured in compliance with the

latest revision of MIL-PRF-38535 QML, making it ideally suited to

military temperature applications demanding the highest level of

performance and reliability.
