PIN DESCRIPTIONS

Pin Name

-A

I/O

Description

Input

I/O

Address: The 15 address inputs select one of 32,768 bytes in the nvSRAM array

Data: Bi-directional 8-bit data bus for accessing the nvSRAM

Chip Enable: The active low E input selects the device

DQ -DQ

Input

Write Enable: The active low W enables data on the DQ pins to be written to the address

location latched by the falling edge of E

Input

Output Enable: The active low G input enables the data output buffers during read cycles.

De-asserting G high caused the DQ pins to tri-state.

Power Supply

I/O

Power: 5.0V, ± 10%

CCX

HSB

Hardware Store Busy: When low this output indicates a Store is in progress. When pulled

low external to the chip, it will initiate a nonvolatile STORE operation. A weak pull up resistor

keeps this pin high if not connected. (Connection Optional).

Power Supply

AutoStore Capacitor: Supplies power to nvSRAM during power loss to store data from

SRAM to nonvolatile storage elements.
