IDT71V321S/L
High Speed 3.3V 2K x 8 Dual-Port Static RAM with Interrupts
Description
The IDT71V321 is a high-speed 2K x 8 Dual-Port Static RAMs with
internal interrupt logic for interprocessor communications. The
IDT71V321 is designed to be used as a stand-alone 8-bit Dual-Port
RAM.
The device provides 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
Industrial and Commercial Temperature Ranges
port to enter a very low standby power mode.
Fabricated using CMOS high-performance technology, these de-
vices typically operate on only 325mW of power. Low-power (L) ver-
sions offer battery backup data retention capability, with each Dual-Port
typically consuming 200µW from a 2V battery.
The IDT71V321 devices are packaged in a 52-pin PLCC, a 64-pin
TQFP (thin quad flatpack), and a 64-pin STQFP (super thin quad
flatpack).
