3.2
The SCK pin is the serial interface's Serial Clock pin.
This pin is connected to the host controllers SCK pin.
The MCP43XX is an SPI slave device, so it’s SCK pin
is an input only pin.
3.3
The SDI pin is the serial interfaces Serial Data In pin.
This pin is connected to the host controllers SDO pin.

The V
3.5
The terminal B pin is connected to the internal
potentiometer’s terminal B.
The potentiometer’s terminal B is the fixed connection
to the zero scale wiper value of the digital
potentiometer. This corresponds to a wiper value of
0x00 for both 7-bit and 8-bit devices.
The terminal B pin does not have a polarity relative to
the terminal W or A pins. The terminal B pin can
support both positive and negative current. The voltage
on terminal B must be between V
MCP43XX devices have four terminal B pins, one for
each resistor network.
3.6
The terminal W pin is connected to the internal
potentiometer’s terminal W (the wiper). The wiper
terminal is the adjustable terminal of the digital
potentiometer. The terminal W pin does not have a
polarity relative to terminals A or B pins. The terminal
W pin can support both positive and negative current.
The voltage on terminal W must be between V
V
MCP43XX devices have four terminal W pins, one for
each resistor network.

The terminal A pin is available on the MCP43X1
devices,
potentiometer’s terminal A.
The potentiometer’s terminal A is the fixed connection
to the full scale wiper value of the digital potentiometer.
This corresponds to a wiper value of 0x100 for 8-bit
devices or 0x80 for 7-bit devices.
The terminal A pin does not have a polarity relative to
the terminal W or B pins. The terminal A pin can
support both positive and negative current. The voltage
on terminal A must be between V
The terminal A pin is not available on the MCP43X2
devices, and the internally terminal A signal is floating.
MCP43X1 devices have four terminal A pins, one for
each resistor network.

The NC pin is not used.
3.9
The RESET pin is used to force the device into the
POR/BOR state.
3.10
The SDO pin is the serial interfaces Serial Data Out pin.
This pin is connected to the host controllers SDI pin.
This pin allows the host controller to read the digital
potentiometers registers, or monitor the state of the
command error bit.
