IDT70V659/58/57S
High-Speed 3.3V 128/64/32K x 36 Asynchronous Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
Description
The IDT70V659/58/57 is a high-speed 128/64/32K x 36 Asynchro-
nous Dual-Port Static RAM. The IDT70V659/58/57 is designed to be used
as a stand-alone 4/2/1Mbit Dual-Port RAM or as a combination MASTER/
SLAVE Dual-Port RAM for 72-bit-or-more word system. Using the IDT
MASTER/SLAVE Dual-Port RAM approach in 72-bit or wider memory
system applications results in full-speed, error-free operation without the
need for additional discrete logic.
This 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 the chip enables (either
CE
0
or CE
1
) permit the
on-chip circuitry of each port to enter a very low standby power mode.
The 70V659/58/57 can support an operating voltage of either 3.3V
or 2.5V on one or both ports, controlled by the OPT pins. The power supply
for the core of the device (V
DD
) remains at 3.3V.
