DESCRIPTION
The ISSI IS63LV1024/IS63LV1024L is a very high-speed,
low power, 131,072-word by 8-bit CMOS static RAM in
revolutionary pinout. The IS63LV1024/IS63LV1024L is fab-
ricated 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 IS63LV1024/IS63LV1024L operates from a single 3.3V
power supply and all inputs are TTL-compatible.
