DESCRIPTION
The ISSI IS62WV5128DALL / IS62WV5128DBLL are
high-speed,4MbitstaticRAMsorganizedas512Kwords
by8bits.ItisfabricatedusingISSI's high-performance
CMOStechnology.Thishighly reliableprocess coupled
with innovative circuit design techniques, yields high-
performance and low power consumption devices.
When CS1 is HIGH (deselected) the device assumes
a standby mode at which the power dissipation can be
reduceddownwithCMOSinputlevels.
Easy memory expansion is provided by using Chip Enable
andOutputEnableinputs.TheactiveLOWWriteEnable
(WE) controls both writing and reading of the memory.
The IS62WV5128DALL and IS62WV5128DBLL are
packagedin the JEDEC standard 32-pinTSOP (TYPE
I),32-pinsTSOP(TYPEI),32-pinTSOP(TypeII),32-pin
SOPand36-pinminiBGA.
