Power Supply Power Supply Inputs to the Device.
Power Supply AutoStore Capacitor. Supplies power to nvSRAM during power loss to store data from SRAM to
Input/Output Hardware Store Busy (HSB). When LOW, this output indicates a Hardware Store is in progress.
No Connect No Connect. This pin is not connected to the die.

Address Inputs. Used to select one of the 2,048 bytes of the nvSRAM.
Write Enable Input, Active LOW. When selected LOW, this writes data on the IO pins to the address
location latched by the falling edge of CE.
Chip Enable Input, Active LOW. When LOW, selects the chip. When HIGH, deselects the chip.
Output Enable, Active LOW. The active LOW OE input enables the data output buffers during read
cycles. Deasserting OE HIGH causes the IO pins to tri-state.
Ground for the Device. Is connected to ground of the system.
When pulled low external to the chip, it initiates a nonvolatile STORE operation. A weak internal pull
up resistor keeps this pin HIGH if not connected (connection optional).
