The CS pin is the chip select input. Forcing the CS pin
to V
can increment and decrement the wiper. Forcing the

commands. These commands can increment and
decrement the wiper and are compatibe with the
MCP402X devices. The wiper is saved to volatile
memory (RAM).
The CS pin has an internal pull-up resistor. The resistor
will become “disabled” when the voltage on the CS pin
is below the V
is “floating”, the CS pin will be pulled to the V

consumption when serial commands are occurring.

The U/D pin input is used to increment or decrement
the wiper on the digital potentiometer. An increment
moves the wiper one step toward terminal A, while a
decrement moves the wiper one step toward
terminal B.
