X9C102/103/104/503
The X9Cxxx are Xicor digitally controlled (XDCP) potentiometers. The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The wiper position is controlled by a threewire 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 or as a two-terminal variable resistor in a wide variety of applications including: control parameter adjustments signal processing

Brief Description
Increment . The INC input is negative-edge triggered. Toggling INC will move the wiper and either increment or decrement the counter in the direction indicated by the logic level on the U/D input.
Up/Down. The U/D input controls the direction of the wiper movement and whether the counter is incremented or decremented. terminals of a mechanical potentiometer. The minimum voltage is 5V and the maximum is +5V. The terminology of VH/RH and VL/RL references the relative position of the terminal in relation to wiper movement direction selected by the U/D input and not the voltage potential on the terminal.
VSS RH/VH. The high (VH/RH) terminals of the X9C102/103/104/503 are equivalent to the fixed

VW/RW
VW/RW. VW/RW is the wiper terminal, and is equivalent to the movable terminal of a mechanical potentiometer. The position of the wiper within the array is determined by the control inputs. The wiper terminal series resistance is typically 40. RL/VL. The low (VL/RL) terminals of the X9C102/103/104/503 are equivalent to the fixed terminals of a mechanical potentiometer. The minimum voltage is 5V and the maximum is +5V. The terminology of VH/RH and VL/RL references the relative position of the terminal in relation to wiper movement direction selected by the U/D input and not the voltage potential on the terminal.
CS. The device is selected when the CS input is LOW. The current counter value is stored in nonvolatile memory when CS is returned HIGH while the INC input is also HIGH. After the store operation is complete the X9C102/103/104/503 device will be placed in the low power standby mode until the device is selected once again. VCC
