16
Input
Address Inputs used to select one of the 131,072 bytes of the nvSRAM
.
DQ0 – DQ7 Input Output
Bidirectional Data IO Lines
. Used as input or output lines depending on operation.
WE
Input
Write Enable Input, Active LOW
. When selected LOW, enables data on the IO pins to be written
to the address location latched by the falling edge of CE.
CE
Input
Chip Enable Input, Active LOW
. When LOW, selects the chip. When HIGH, deselects the chip.
OE
Input
Output Enable, Active LOW
. The active LOW OE input enables the data output buffers during read
cycles. IO pins are tri-stated on deasserting OE high.
V
SS
Ground
Ground For The Device.
Must be connected to ground of the system.
V
CC
Power Supply
Power Supply Inputs To The Device
.
HSB
Input Output
Hardware Store Busy (HSB)
. When low this output indicates a hardware store is in progress. 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)
V
CAP
Power Supply
Autostore Capacitor
. Supplies power to nvSRAM during power loss to store data from SRAM to
nonvolatile elements.
NC
No Connect
No Connect
. Do not connect this pin to the die.
