DESCRIPTION
The Xicor X9C303 is a digitally controlled potentiome-
ter (XDCP). The device consists of a resistor array,
wiper switches, a control section, and nonvolatile
memory. The wiper position is controlled by a three-
wire interface.
The resistor array is composed of 99 resistive ele-
ments. Between each element and at either end are
tap points accessible to the wiper terminal. The posi-
tion of the wiper element is controlled by the CS, U/D,
and INC inputs. The position of the wiper can be
stored in nonvolatile memory and then be recalled
upon a subsequent power-up operation.
The device can be used as a three-terminal potentio-
meter or as a two-terminal variable resistor in a wide
variety of applications ranging from control, to signal
processing, to parameter adjustment. Digitally-
controlled potentiometers provide three powerful appli-
cation advantages; (1) the variability and reliability of a
solid-state potentiometer, (2) the flexibility of com-
puter-based digital controls, and (3) the use of nonvol-
atile memory for potentiometer settings retention.
