Description

A0–A12

 

 

 

 

 

 

 

Input

Address Inputs. Used to select one of the 8,192 bytes of the nvSRAM.

DQ0-DQ7

 

 

 

 

 

 

 

Input/Output

Bidirectional Data I/O Lines. Used as input or output lines depending on operation.

 

 

 

 

 

 

 

 

 

 

 

 

Input

Write Enable Input, Active LOW. When the chip is enabled and

 

is LOW, data on the I/O
