DESCRIPTION
The ISSI IS62WV10248DALL/ IS62WV10248DBLL are
high-speed,8MbitstaticRAMsorganizedas1Mwords
by8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 CS1 isHIGH (deselected)orwhenCS2isLOW
(deselected), the device assumes a standby mode at
which the power dissipation can be reduced down with
CMOSinputlevels.
Easy memory expansion is provided by using Chip Enable
andOutputEnableinputs.TheactiveLOWWriteEnable
(WE) controls both writing and reading of the memory.
The IS62WV10248DALL and IS62WV10248DBLL are
packagedintheJEDECstandard48-pinminiBGA(9mm
x 11mm) and 44-PinTSOP(TYPEII).
