... Datasheet Terminal Voltage 0V to 13.2V, 128 Taps Up/Down Interface 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 ...

... ISL95310 will be placed in the low power standby mode until the device is selected once again. Principles of Operation There are three sections of the ISL95310: the input control, reaches its CC counter and decode section; the nonvolatile memory; and the resistor array. The input control section operates just like an up/down counter ...

... The value of the counter is stored in nonvolatile memory whenever CS transitions HIGH while the INC input is also HIGH. The system may select the ISL95310, move the wiper and deselect the device without having to store the latest wiper position in nonvolatile memory. After the wiper movement is ...
