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.
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 three-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.
