Description:

TheIDT70T3719/99Misa high-speed256K/128Kx72bitsynchro-

nousDual-PortRAM.ThememoryarrayutilizesDual-Portmemorycells

toallowsimultaneousaccessofanyaddressfrombothports.Registerson

control,data,andaddressinputsprovideminimalsetupandholdtimes.

The timing latitude provided by this approach allows systems to be

designed with very short cycle times. With an input data register, the

IDT70T3719/99Mhasbeenoptimizedforapplicationshavingunidirec-

tionalorbidirectionaldataflowinbursts.Anautomaticpowerdownfeature,

controlled by CE0 and CE1, permits the on-chip circuitry of each port to

enter a very low standby power mode.

The 70T3719/99M can support an operating voltage of either 3.3V

or 2.5V on one or both ports, controllable by the OPT pins. The power

supply for the core of the device (VDD) is at 2.5V.
