August 27, 2015 Digitally Controlled Potentiometer (XDCPв„ў), 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. Features 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 be directly written to and read by the user. The
contents of the WR controls the position of the wiper on the
resistor array through the switches. At power-up, the device
recalls the contents of the default data registers to the
corresponding WR. 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. DCP terminal voltage, 0 to +13.2V The device can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of …
