Digitally Controlled Potentiometer  
(XDCP™)  
Features  
• Solid-state potentiometer  
• 3-wire serial interface  
• 32 wiper tap points  
The Intersil X9315 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 a 3-wire interface.  
- Wiper position stored in nonvolatile memory and  
recalled on power-up  
The potentiometer is implemented by a resistor array  
composed of 31 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.  
• 31 resistive elements  
- Temperature compensated  
- End to end resistance range ± 20%  
- Terminal voltage, 0 to V  
CC  
• Low power CMOS  
- V  
CC  
= 2.7V or 5V  
- Active current, 80/400µA max.  
- Standby current, 5µA max.  
The device can be used as a three-terminal potentiometer or  
as a two-terminal variable resistor in a wide variety of  
applications including:  
• High reliability  
- Endurance, 100,000 data changes per bit  
- Register data retention, 100 years  
• Control  
• Parameter Adjustments  
• Signal Processing  
• R

values = 10kΩ, 50kΩ, 100kΩ  
• Packages  
- 8 Ld SOIC, MSOP and PDIP  
• Pb-free available (RoHS compliant)
