DESCRIPTION
The ISSI IS62/65LV256AL 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 15 ns maximum.
When CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation is reduced to
150 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 IS62/65LV256AL is available in the JEDEC standard
28-pin SOJ, 28-pin SOP, and the 28-pin TSOP (Type I)
package.
