be left open if not connected.

A2–A0 [3]

Input

be left open if not connected.

Power supply AutoStore Capacitor. Supplies power to the nvSRAM during power loss to STORE data from the

SRAM to nonvolatile elements. If not required, AutoStore must be disabled and this pin left as no

connect. It must never be connected to ground.

NC

No connect

No Connect. This pin is not connected to the die.
