FEATURES
DESCRIPTION
The ISSI IS62C1024AL/IS65C1024AL is a low power,
131,072-word by 8-bit CMOS static RAM. It is fabricated
using high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design
techniques, yields higher performance and low power
consumption devices.
•ꢀ High-speedꢀaccessꢀtime:ꢀ35,ꢀ45ꢀnsꢀ
• Low active power: 100 mW (typical)
• Low standby power: 20 µW (typical) CMOS
standby
•ꢀ OutputꢀEnableꢀ(OE) and two Chip Enable
(CE1 and CE2) inputs for ease in applications
WhenCE1isHIGHorCE2isLOW(deselected),thedevice
assumes a standby mode at which the power dissipation
can be reduced by using CMOS input levels.
•ꢀ Fullyꢀstaticꢀoperation:ꢀnoꢀclockꢀorꢀrefreshꢀ
required
•ꢀ TTLꢀcompatibleꢀinputsꢀandꢀoutputs
•ꢀ Singleꢀ5Vꢀ(±10%)ꢀpowerꢀsupply
Easy memory expansion is provided by using two Chip
Enableinputs,CE1andCE2.TheactiveLOWWriteEnable
(WE) controls both writing and reading of the memory.
