DESCRIPTION
The
ISSI
IS61LV256 is a very high-speed, low power,
32,768-word by 8-bit static RAM. It is fabricated using
ISSI
's high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design
techniques, yields access times as fast as 8 ns maximum.
When
CE
is HIGH (deselected), the device assumes a
standby mode at which the power dissipation is reduced to
50 μW (typical) with CMOS input levels.
Easy memory expansion is provided by using an active
LOW Chip Enable (
CE
). The active LOW Write Enable
(
WE
) controls both writing and reading of the memory.
The IS61LV256 is available in the JEDEC standard 28-pin,
300-mil SOJ and the 450-mil TSOP (Type I) package.
