Input
Address Inputs used to select one of the address locations.
7-10, 13-16, 29-32, 35-38 Input/Output Bidirectional Data I/O lines. Used as input or output lines
depending on operation.
1, 22, 23, 28
No Connect No Connects. Not connected to the die.
17
Input/Control Write Enable Input, active LOW. When selected LOW, a Write is
conducted. When deselected HIGH, a Read is conducted.
6
Input/Control Chip Enable Input, active LOW. When LOW, selects the chip.
When HIGH, deselects the chip.
40, 39
41
Input/Control Byte Write Select Inputs, active LOW. BHE controls I/O16–I/O9,
BLE controls I/O8–I/O1.
Input/Control 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.
12, 34
Ground Ground for the device. Should be connected to ground of the
system.
11, 33
Power Supply Power Supply inputs to the device.
