DESCRIPTION

The ICSI IC61LV256 is a very high-speed, low power, 32,768-word by 8-bit static RAM. It is fabricated using ICSIs 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 600 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 IC61LV256 is available in the JEDEC standard 28-pin, 300mil SOJ and the 8*13.4mm TSOP-1 package.
