FEATURES  
DESCRIPTION  
• Solid-State Potentiometer  
• SPI serial interface  
• Register oriented format  
—Direct read/write/transfer wiper positions  
—Store as many as four positions per  
potentiometer  
The X9420 integrates a single digitally controlled  
potentiometers (XDCP) on a monolithic CMOS  
integrated microcircuit.  
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

—Register data retention–100 years  
• 8-bytes of nonvolatile EEPROM memory

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.  
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.
