DESCRIPTION
The
8192-word by 8-bit static RAM. It is fabricated using
high-performance CMOS technology. This highly reliable pro-
cess coupled with innovative circuit design techniques, yields
access times as fast as 15 ns with low power consumption.
When CE1 is HIGH or CE2 is LOW (deselected), the device
assumes a standby mode at which the power dissipation can
be reduced down to 250 µW (typical) with CMOS input levels.
Easy memory expansion is provided by using two Chip Enable
inputs, CE1 and CE2. The active LOW Write Enable (WE)
controls both writing and reading of the memory.
The IS61C64AH is packaged in the JEDEC standard 28-pin,
300mil SOJ and 330mil SOP.
