I/O Type
Input
Input/Output
Bidirectional Data I/O lines
. Used as input or output lines depending on operation.
Input
Write Enable Input, active LOW
. When selected LOW, enables data on the I/O pins to be written to
the address location latched by the falling edge of CE.
Input
Chip Enable Input, active LOW
. When LOW, selects the chip. When HIGH, deselects the chip.
Input
Output Enable, active LOW
. The active LOW OE input enables the data output buffers during read
cycles. Deasserting OE HIGH causes the I/O pins to tri-state.
Ground
Ground for the device
.
Should be connected to ground of the system.
Power Supply
Power Supply inputs to the device
.
Input/Output
Hardware Store Busy
. When low this output indicates a Hardware Store is in progress. When pulled
low external to the chip it will initiate a nonvolatile STORE operation. A weak internal pull-up resistor
keeps this pin high if not connected. (Connection Optional)
Power Supply
Autostore
Capacitor
. Supplies power to nvSRAM during power loss to store data from SRAM to
nonvolatile elements.
No Connect
No Connects.
This pin is not connected to the die
Description
