128K x 16 HIGH SPEED ASYNCHRONOUS CMOS STATIC RAM WITH ECC

DESCRIPTIONThe ISSI IS61/64WV12816EDBLL is a high-speed,2,097,152-bit staticRAMsorganizedas131,072wordsby16bits.ItisfabricatedusingISSI'shigh-performanceCMOS technology.Thishighly reliableprocesscoupledwith innovative circuit design techniques, yields high-performanceandlowpowerconsumptiondevices.

WhenCE isHIGH (deselected), thedeviceassumesastandbymodeatwhichthepowerdissipationcanbere-duceddownwithCMOSinputlevels.

EasymemoryexpansionisprovidedbyusingChipEnableandOutputEnableinputs,CEandOE.TheactiveLOWWriteEnable(WE)controlsbothwritingandreadingofthememory.AdatabyteallowsUpperByte(UB)andLowerByte(LB)access.

TheIS61/64WV12816EDBLLispackagedintheJEDECstandard44-pinTSOP-II and48-pinMiniBGA(6mmx8mm).
