DESCRIPTION
TheISSIIS61WV12816DAxx/DBxxandIS64WV12816D-
Bxxarehigh-speed,2,097,152-bitstaticRAMsorganized
as131,072wordsby16bits.ItisfabricatedusingISSI's
high-performanceCMOStechnology.Thishighlyreliable
process coupled with innovative circuit design techniques,
yields high-performance and low power consumption
devices.
When CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be re-
duced down with CMOS input levels.
EasymemoryexpansionisprovidedbyusingChipEnable
andOutputEnableinputs,CEandOE.TheactiveLOW
Write Enable (WE) controls both writing and reading of the
memory. A data byte allows Upper Byte (UB) and Lower
Byte (LB) access.
The IS61WV12816DAxx/DBxx and IS64WV12816DBxx
arepackagedintheJEDECstandard44-pinTSOPType
IIand48-pinMiniBGA(6mmx8mm).
