    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.
