... AA high-performance applications. When CE is high the devices enter standby mode. The AS7C1026A is guaranteed not to exceed 55 mW power consumption in CMOS standby mode. The devices also offer 2.0V data retention. A write cycle is accomplished by asserting write enable (WE) and chip enable (CE). Data on the input pins I/O0–I/O15 is written on the rising edge of WE (write cycle (write cycle 2) ...
