Overview

WCMA2008U1B WCMA2008U1B 256K x 8 Static RAM Features • High Speed — 70ns availability • Voltage range — 2.
7V–3.
3V • Ultra low active power — Typical active current: 1 mA @ f = 1MHz — Typical active current: 7 mA @ f = fmax (70ns speed) • Low standby power • Easy memory expansion with CE1,CE2 ,and OE features • Automatic power-down when deselected • CMOS for optimum speed/power reduces power consumption by 80% when addresses are not toggling.
The device can be put into standby mode reducing power consumption by more than 99% when deselected (CE 1 HIGH or CE2 LOW).
Writing to the device is accomplished by taking Chip Enable (CE 1) and Write Enable (WE) inputs LOW and Chip Enable 2 (CE 2) HIG...
