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

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.

Fabricated using CMOS high-performance technology, 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.

1. This parameter is determined by device characterization but is not production

tested.

2. 3dV represents the interpolated capacitance when the input and output signals

switch from 3V to 0V.
