Pin Descriptions
A0-A15 Address Inputs These 16 address inputs select one of the 64K x 16 bit segments in the RAM. CE Chip Enable Input CE is active LOW. It must be active to read from or write to the device. If 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. OE Output Enable Input The output enable input is active LOW. When OE is Low with CE 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.
V61C51161024
UBE, LEB Byte Enable Active low inputs. These inputs are used to enable the upper or lower data byte. WE Write Enable Input 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. I/O0-I/O15 Data Input and Data Output Ports These 16 bidirectional ports are used to read data from and write data into the RAM. VCC GND Power Supply Ground

NOTES: 1. The internal write time of the memory is defined by the overlap of CE 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 CE or WE going high. 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 CE is LOW 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 CE going low to the end of write.
