Low Noise/Low Power/SPI Bus  
Data Sheet  
March 7, 2005  
FN8195.0  
DESCRIPTION  
Single Digitally Controlled (XDCP™)  
Potentiometer  
The X9420 integrates a single digitally controlled  
potentiometers (XDCP) on a monolithic CMOS  
integrated microcircuit.  
FEATURES  
• Solid-State Potentiometer  
• SPI serial interface  
• Register oriented format  
—Direct read/write/transfer wiper positions  
—Store as many as four positions per  
potentiometer  
The digitally controlled potentiometer is implemented  
using 63 resistive elements in a series array. Between  
each element are tap points connected to the wiper  
terminal through switches. The position of the wiper on  
the array is controlled by the user through the SPI bus  
interface. The potentiometer has associated with it a  
volatile Wiper Counter Register (WCR) and 4  
nonvolatile Data Registers (DR0:DR3) that can be  
directly written to and read by the user. The contents  
of the WCR controls the position of the wiper on the  
resistor array through the switches. Power-up recalls  
the contents of DR0 to the WCR.  
• Power supplies  
—V  
= 2.7V to 5.5V  
CC  
—V+ = 2.7V to 5.5V  
—V– = -2.7V to -5.5V  
• Low power CMOS  
—Standby current < 1µA  
• High reliability  
—Endurance–100,000 data changes per bit per  
register  
The XDCP 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, and signal processing.  
—Register data retention–100 years  
• 8-bytes of nonvolatile EEPROM memory  
• 10kΩ or 2.5kΩ resistor arrays  
• Resolution: 64 taps each pot  
• 14-lead TSSOP, 16-lead SOIC, and 16-pin plastic  
DIP packages
