This device has an automatic power-down feature that significantly reduces power consumption when deselected. 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/O1 through I/O8 , is written into the location specified on the address pins A0 through A15 . If Byte High Enable BHE is LOW, then data from I/O pins I/O9 through I/O16 is written into the location specified on the address pins A0 through A15 . Reading from the device is accomplished by taking Chip Enable CE and Output Enable OE LOW while forcing the Write Enable WE HIGH. If Byte Low Enable BLE is LOW, then data from the memory location specified by the address pins will appear on I/O1 to I/O8. If Byte High Enable BHE is LOW, then data from memory will appear on I/O9 to I/O16. See the truth table at the back of this data sheet for a complete description of read and write modes. The input/output pins I/O1 through I/O16 are placed in a high-impedance state when the device is deselected CE HIGH , the outputs are disabled OE HIGH , the BHE and BLE are disabled BHE, BLE HIGH , or during a write operation CE LOW, and WE LOW .
