. Data lines. Used as input or output lines depending on operation.
Input/control WE. Write Enable, Active LOW. When selected LOW, a WRITE is conducted. When selected HIGH, a READ is
conducted.
Input/control CE

. Chip Enable 1, Active LOW.
Input/control CE
2
. Chip Enable 2, Active HIGH.
Input/control OE. Output Enable, Active LOW. Controls the direction of the I/O pins. When LOW, the I/O pins behave as outputs.
When de-asserted HIGH, I/O pins are tri-stated, and act as input data pins.
Ground GND. Ground for the device.
Power supply V
CC
. Power supply for the device.
