Pin Name

Alt

IO Type

Description

A0–A14

Input

Address Inputs. Used to select one of the 32,768 bytes of the nvSRAM.

DQ0-DQ7

Input or

Bidirectional Data IO lines. Used as input or output lines depending on operation.

Output

Input

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

is LOW, data on the

IO pins is written to the specific address location.

Input

Chip Enable Input, Active LOW. When LOW, selects the chip. When HIGH, deselects the

chip.

Input

Output Enable, Active LOW. The active LOW

input enables the data output buffers

during read cycles. Deasserting OE HIGH causes the IO pins to tri-state.

VSS

Ground

Ground for the Device. The device is connected to ground of the system.

VCC

Power Supply

Power Supply Inputs to the Device.
