IDT71321SA/LA and IDT71421SA/LA
High Speed 2K x 8 Dual-Port Static RAM with Interrupts
Description
The IDT71321/IDT71421 are high-speed 2K x 8 Dual-Port Static
RAMs with internal interrupt logic for interprocessor communications.
The IDT71321 is designed to be used as a stand-alone 8-bit Dual-
Port Static RAM or as a "MASTER" Dual-Port Static RAM together
with the IDT71421 "SLAVE" Dual-Port in 16-bit-or-more word width
systems. Using the IDT MASTER/SLAVE Dual-Port Static RAM ap-
proach 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 I/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 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 IDT71321/IDT71421 devices are packaged in 52-pin PLCCs,
64-pin TQFPs, and 64-pin STQFPs.
