... Device Select Device Select 1 March 4, 2005 DESCRIPTION The Intersil X93255 is a dual digitally controlled potentiometer (XDCP). The device consists of two resistor arrays, wiper switches, a control section, and nonvolatile memory. The wiper positions are controlled by individual Up/Down interfaces. A potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching network ...

... X93255 PRINCIPLES OF OPERATION There are multiple sections for each potentiometer in the X93255: an input control, a counter and decode section; the nonvolatile memory; and a resistor array. Each input control section operates just like an up/down counter. . The terminology The output of this counter is decoded to turn on a single ...

... When left open, each CS pin is internally pulled internal 30K resistor. CC The system may select the X93255, move any wiper and deselect the device without having to store the latest wiper position in nonvolatile memory. After the wiper movement is performed as described above and once the new position is reached, the system must keep INC LOW while taking CS HIGH ...
