7132SA/LA and 7142SA/LA
High Speed 2K x 8 Dual Port Static RAM
Military, Industrial and Commercial Temperature Ranges
Description
The IDT7132/IDT7142 are high-speed 2K x 8 Dual-Port Static RAMs.
The IDT7132 is designed to be used as a stand-alone 8-bit Dual-Port RAM
or as a “MASTER” Dual-Port RAM together with the IDT7142 “SLAVE”
Dual-Port in 16-bit-or-more word width systems. Using the IDT MASTER/
SLAVE Dual-Port RAM approach in 16-or-more-bit memory system
applications results in full-speed, error-free operation without the need for
additional discrete logic.
Both devices provide two independent ports with separate control,
address, and l/O pins that permit independent, asynchronous access for
reads or writes to any location in memory. An automatic power down
feature, controlled by CE permits the on-chip circuitry of each port to enter
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.
