s Up/Down Interface FN8083 Rev 1.00 August 27, 2015 The Intersil ISL95310 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 an Up/Down interface. The potentiometer is implemented by a resistor array composed of 127 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. The wiper of each potentiometer has an associated volatile Wiper Counter Register (WR) and a non-volatile Initial Value Register (IVR) that can
