These inputs are used to enable the upper or lower data byte. Pin Descriptions A 0–A17 Address Inputs These 18 address inputs select one of the 256K x 16 bit segments in the RAM. Write Enable Input WE The write enable input is active LOW and controls read and write operations. With the chip enabled, when WE is HIGH and OE is LOW, output data will be present at the I/O pins; when WE is LOW and OE is HIGH, the data present on the I/O pins will be written into the selected memory locations. CE1, CE2* Chip Enable Inputs CE1 is active LOW and CE2 is active HIGH. Both chip enables must be active to read from or write to the device. If either chip enable is not active, the device is deselected and is in a standby power mode. The I/O pins will be in the high-impedance state when deselected. I/O1–I/O16 Data Input and Data Output Ports These 16 bidirectional ports are used to read data from and write data into the RAM. OE Output Enable Input The output enable input is active LOW. With chip enabled, when OE is Low and WE High, data will be presented on the I/O pins. The I/O pins will be in the high impedance state when OE is High. VCC Power Supply GND Ground *CE2 is available on BGA package only.

The internal write time of the memory is defined by the overlap of CE1 and CE2 active and WE low. All signals must be active to initiate and any one signal can terminate a write by going inactive. The data input setup and hold timing should be referenced to the second transition edge of the signal that terminates the write. 2. tWR is measured from the earlier of CE1 or WE going high, or CE2 going LOW at the end of the write cycle. 3. During this period, I/O pins are in the output state so that the input signals of opposite phase to the outputs must not be applied. 4. OE = VIL or VIH. However it is recommended to keep OE at VIH during write cycle to avoid bus contention. 5. If CE1 is LOW and CE2 is HIGH during this period, I/O pins are in the output state. Then the data input signals of opposite phase to the outputs must not be applied to them. 6. tCW is measured from CE1 going low or CE2 going HIGH to the end of write. 7. CE2 is available on BGA package only.
