Quick Detail:
HIGH-SPEED 2K x 8 DUAL-PORT STATIC RAM
Description:
Static RAMs. The IDT7132 is designed to be used as a standalone
8-bit Dual-Port RAM or as a “MASTER” Dual-Port RAM together with
the IDT7142 “SLAVE” Dual-Port in 16-bit-ormore 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 IDT’s CMOS high-performance technology, these
devices typically operate on only 550mW 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 Side braze 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-STD-883, Class B, making it ideally suited
to military temperature applications demanding the highest level of
performance and reliability
