Input
Input/Output I/O0–I/O7. Data lines. Used as input or output lines depending on operation
Description
A0–A14. Address Inputs
Input/Control WE. When selected LOW, a WRITE is conducted. When selected HIGH, a READ is
conducted
20
22
Input/Control CE. When LOW, selects the chip. When HIGH, deselects the chip
Input/Control OE. Output Enable. Controls the direction of the I/O pins. When LOW, the I/O pins
behave as outputs. When deasserted HIGH, I/O pins are tri-stated, and act as input
data pins
14
Ground
GND. Ground for the device
28
Power Supply VCC. Power supply for the device
Note:
2. Typical specifications are the mean values measured over a large sample size across normal production process variations and are taken at nominal conditions
(T = 25°C, V ). Parameters are guaranteed by design and characterization, and not 100% tested.
