Address Inputs. Used to select one of the 131,072 bytes of the nvSRAM.
Write Enable Input, Active LOW. When the chip is enabled and WE is LOW, data on the IO
pins is written to the specific address location.
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. 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).
to nonvolatile elements.
No Connect. This pin is not connected to the die.
