Description

TheIDT7132/IDT7142arehigh-speed2Kx8Dual-PortStaticRAMs.

TheIDT7132isdesignedtobeusedasastand-alone8-bitDual-PortRAM

or as a “MASTER” Dual-Port RAM together with the IDT7142 “SLAVE”

Dual-Portin16-bit-or-morewordwidthsystems.UsingtheIDTMASTER/

SLAVE Dual-Port RAM approach in 16-or-more-bit memory system

applicationsresultsinfull-speed,error-freeoperationwithouttheneedfor

additionaldiscretelogic.

Both devices provide two independent ports with separate control,

address,andl/Opinsthatpermitindependent,asynchronousaccessfor

reads or writes to any location in memory. An automatic power down

feature,controlledbyCEpermitstheon-chipcircuitryofeachporttoenter

a very low standby power mode.

FabricatedusingIDT’sCMOShigh-performancetechnology,these

devices typically operate on only 325mW of power. Low-power (LA)

versions offer battery backup data retention capability, with each Dual-

Port typically consuming 200µW from a 2V battery.

The IDT7132/7142 devices are packaged in a 48-pin sidebraze or

plastic DIPs, 48-pin LCCs, 52-pin PLCCs, and 48-lead flatpacks.

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.
