Description

The IDT70V659/58/57 is a high-speed 128/64/32K x 36 Asynchro-

nousDual-PortStaticRAM.TheIDT70V659/58/57isdesignedtobeused

asastand-alone4/2/1MbitDual-PortRAMorasacombinationMASTER/

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

CE0 or CE1) 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

or2.5Vononeorbothports,controlledbytheOPTpins.Thepowersupply

for the core of the device (VDD) remains at 3.3V.
