DESCRIPTION
The ISSI IS61LV3216L is a high-speed, 512K static RAM
organized as 32,768 words by 16 bits. It is fabricated using
ISSI's high-performance CMOS technology. This highly reli-
able process coupled with innovative circuit design tech-
niques, yields fast access times with low power consumption.
When CE is HIGH (deselected), the device assumes a standby
mode at which the power dissipation can be reduced down to
150 µW (typical) with CMOS input levels.
Easy memory expansion is provided by using Chip Enable
and Output Enable inputs, CE and OE. The active LOW Write
Enable (WE) controls both writing and reading of the memory.A
data byte allows Upper Byte (UB) and Lower Byte (LB) access.
The IS61LV3216L is packaged in the JEDEC standard 44-pin
400-mil SOJ and 44-pin TSOP (Type II).
