DESCRIPTION
The ISSI IS61LV5128 is a very high-speed, low power,
524,288-word by 8-bit CMOS static RAM. The IS61LV5128
is fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields higher performance
and low power consumption devices.
When CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be
reduced down to 250 µW (typical) with CMOS input levels.
The IS61LV5128 operates from a single 3.3V power
supply and all inputs are TTL-compatible.
The IS61LV5128 is available in 36-pin 400-mil SOJ, 36pin mini BGA, and 44-pin TSOP (Type II) packages.
