RENESAS X9317WV8Z-2.7

The Intersil X9317 is a digitally controlled potentiometer (XDCP™). The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The wiper position is controlled by a 3 - wire interface. The potentiometer is implemented by a resistor array composed of 99 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. The position 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 potentiometer for voltage control or as a two - terminal variable resistor for current control in a wide variety of applications.
