Digitally Controlled Potentiometer  
(XDCP™)  
Features  
• Solid-State Potentiometer  
• Three-Wire Serial Interface  
• 100 Wiper Tap Points  
The X9C102, X9C103, X9C104, X9C503 are Intersils’  
digitally controlled (XDCP) potentiometers. The device  
consists of a resistor array, wiper switches, a control section,  
and non-volatile memory. The wiper position is controlled by  
a three-wire interface.  
- Wiper Position Stored in Non-volatile Memory and  
Recalled on Power-up  
• 99 Resistive Elements  
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 non-volatile  
memory and then be recalled upon a subsequent power-up  
operation.  
- Temperature Compensated  
- End-to-End Resistance, ±20%  
- Terminal Voltages, ±5V  
• Low Power CMOS  
- VCC = 5V  
- Active Current, 3mA max.  
- Standby Current, 750µA max.  
The device can be used as a three-terminal potentiometer or  
as a two-terminal variable resistor in a wide variety of  
applications ranging from control to signal processing to  
parameter adjustment.  
• High Reliability  
- Endurance, 100,000 Data Changes per Bit  
- Register Data Retention, 100 years  
• X9C102 = 1kΩ  
• X9C103 = 10kΩ  
• X9C503 = 50kΩ  
• X9C104 = 100kΩ
