FEATURES  
DESCRIPTION  
• Solid state potentiometer  
• 2-wire serial interface  
• Register oriented format  
—Direct Read/Write/Transfer wiper position  
—Store as many as four positions per  
potentiometer  
The X9428 integrates  
potentiometers (XDCP) on a monolithic CMOS  
integrated microcircuit.  
a
digitally controlled  
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 2-wire  
bus interface. Each 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  
—Ideal for battery operated applications  
• High reliability  
—Endurance–100,000 Data changes per bit per  
register  
—Register data retention–100 years  
• 4-bytes of nonvolatile memory  
• 10kresistor array  
• Resolution: 64 taps each potentiometer  
• 16 Ld SOIC, 14 Ld TSSOP packages  
• Pb-free plus anneal available (RoHS compliant)  
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.
