I/O Type
Address Inputs used to select one of the address locations.
Bidirectional Data I/O lines. Used as input or output lines depending on operation.
No Connects. This pin is not connected to the die.
Write Enable Input, active LOW. When selected LOW, a Write is conducted. When
selected HIGH, a Read is conducted.
Chip Enable Input, active LOW. When LOW, selects the chip. When HIGH,
deselects the chip.
Byte Write Select Inputs, active LOW. BHE controls I/O
I/O
Output Enable, active LOW. Controls the direction of the I/O pins. When LOW, the
I/O pins are allowed to behave as outputs. When deasserted HIGH, I/O pins are
tri-stated, and act as input data pins.
Ground for the device. Should be connected to ground of the system.
Power Supply inputs to the device.
