CG6257AM Datasheet | Weida Semiconductor

PRELIMINARY 4Mb (256K x 16) Pseudo Static RAM Features - Wide voltage range: 2.70V- 3.30V - Access Time: 70ns - Ultra-low active power - Typical active current: 2.0mA @ f = 1 MHz - - - - - Typical active current: 13mA @ f = fmax Ultra low standby power Automatic power-down when deselected CMOS for optimum speed/power Offered in a 48 Ball BGA Package when deselected (CE HIGH or both BHE and BLE are HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE HIGH ), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a write operation (CE LOW and WE LOW). The addresses must...
