DESCRIPTION  
¥ Solid-State Potentiometer  
¥ Three-Wire Serial Interface  
¥ 100 Wiper Tap Points  
ÑWiper Position Stored in Nonvolatile Memory  
and Recalled on Power-up  
The Xicor X9C303 is a digitally-controlled (DCP)  
potentiometer. The device consists of a resistor array,  
wiper switches, a control section, and nonvolatile  
memory. The wiper position is controlled by a three-wire  
interface.  
¥ 99 Resistive Elements, Log Taper  
ÑTemperature Compensated  
ÑEnd to End Resistance, ±15%  
ÑTerminal Voltages, ±5V  
The resistor array is composed of 99 resistive elements.  
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.  
¥ Low Power CMOS  
ÑV = 5V

ÑActive Current, 3mA Max.  
ÑStandby Current, 500µA Max.  
¥ High Reliability

potentiometer or as a two-terminal variable resistor in a  
wide variety of applications ranging from control, to signal  
processing, to parameter adjustment. Digitally-controlled  
potentiometers provide three powerful application  
advantages; (1) the variability and reliability of a solid-  
state potentiometer, (2) the ßexibility of computer-based  
digital controls, and (3) the use of nonvolatile memory for  
potentiometer settings retention.
