Description

The IDT70P35/34L (IDT70P25/24L) is a high-speed 8/4K x 18

(8/4Kx16)Dual-PortStaticRAM. TheIDT70P35/34L(IDT70P25/24L)

is designed to be used as a stand-alone Dual-Port RAM or as a

combinationMASTER/SLAVEDual-PortRAMfor36-bit(32-bit)orwider

memory system applications results in full-speed, error-free operation

withouttheneedforadditionaldiscretelogic.

This device provides two independent ports with separate control,

address,andI/Opinsthatpermitindependent,asynchronousaccessfor

reads or writes to any location in memory. An automatic power down

featurecontrolledbyCEpermitstheon-chipcircuitryofeachporttoenter

a very low standby power mode.

FabricatedusingIDT’sCMOShigh-performancetechnology,these

devices typically operate on only 30.6mW of power.
