The IS63LV1024 is fabricated using ISSI's highperformance 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 W (typical) with CMOS input levels. The IS63LV1024 operates from a single 3.3V power supply and all inputs are TTL-compatible.
