CY62146V MoBL® 4M (256K x 16) Static RAM Features • • • • • • • Wide voltage range: 2.7V–3.6V Ultra-low active, standby power Easy memory expansion with CE and OE features TTL-compatible inputs and outputs Automatic power-down when deselected CMOS for optimum speed/power Package available in a standard 44-Pin TSOP Type II (forward pinout) package deselected (CE 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), BHE and BLE are disabled (BHE, BLE HIGH), or during a write operation (CE LOW, and WE LOW). Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O0 through I/O7), is written into the location specified on the address pins (A0 through A16). If Byte High Enable (BHE) is LOW, then data from I/O pins (I/O8 through I/O15) is written into the location specified on the address pins (A0 .
