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
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
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: 5.0V, +10%
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).
SRAM to nonvolatile storage elements.
Ground
Chip Enable: The active low E input selects the device
AutoStore Capacitor: Supplies power to nvSRAM during power loss to store data from
