0 July 1998 1 MOSEL VITELIC 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...
