DESCRIPTION
TheꢀISSIꢀIS62/65WV1288DALLꢀandꢀIS62/65WV1288DBLLꢀ
areꢀ ꢀ high-speed,ꢀ 1Mꢀ bitꢀ staticꢀ RAMsꢀ organizedꢀ asꢀ
128Kꢀwordsꢀbyꢀ8ꢀbits.ꢀItꢀisꢀfabricatedꢀusingꢀISSI's high-
performanceꢀCMOSꢀtechnology.ꢀThisꢀhighlyꢀreliableꢀprocessꢀ
coupled with innovative circuit design techniques, yields
high-performance and low power consumption devices.
•ꢀ High-speedꢀaccessꢀtime:ꢀꢀ35ns,ꢀ45ns,ꢀ55ns
•ꢀ CMOSꢀlowꢀpowerꢀoperation:
12 mW (typical) operating
ꢀ ꢀ4ꢀµWꢀ(typical)ꢀCMOSꢀstandby
•ꢀ TTLꢀcompatibleꢀinterfaceꢀlevels
•ꢀ Singleꢀpowerꢀsupply:ꢀꢀ
When CS1ꢀisꢀHIGHꢀ(deselected)ꢀorꢀwhenꢀCS2ꢀisꢀLOW
(deselected), the device assumes a standby mode at
which the power dissipation can be reduced down with
CMOSꢀinputꢀlevels.
ꢀ ꢀ1.65V--2.2VꢀVdd (62WV1288dALL)
ꢀ ꢀ2.3V--3.6VꢀVdd (62WV1288dBLL)
Easy memory expansion is provided by using Chip Enable
andꢀOutputꢀEnableꢀinputs.ꢀTheꢀactiveꢀLOWꢀWriteꢀEnableꢀ
(WE) controls both writing and reading of the memory.
