IDT71V30S/L
High-Speed 1K x 8 Dual-Port Static RAM with Interrupts
Industrial and Commercial Temperature Ranges
Description
The IDT71V30 is a high-speed 1K x 8 Dual-Port Static RAM. The
IDT71V30 is designed to be used as a stand-alone 8-bit Dual-Port
SRAM.
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 375mW of power. Low-power (L)
versions offer battery backup data retention capability, with each Dual-
Port typically consuming 200µW from a 2V battery.
The IDT71V30 devices are packaged in 64-pin STQFPs.
