Digitally Controlled Potentiometer (XDCP)  
FEATURES  
DESCRIPTION  
• Solid-state potentiometer  
• 3-wire serial interface  
• 100 wiper tap points  
—Wiper position stored in nonvolatile memory  
and recalled on power-up  
• 99 resistive elements  
The X9Cxxx are Xicor digitally controlled (XDCP)  
potentiometers. The device consists of a resistor array,  
wiper switches, a control section, and nonvolatile  
memory. The wiper position is controlled by a three-  
wire interface.  
The potentiometer is implemented by a resistor array  
composed of 99 resistive elements and a wiper switch-  
ing 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.  
Temperature compensated  
—End to end resistance, ±20%  
Terminal voltages, ±5V  
• Low power CMOS  
—V = 5V  
CC  
—Active current, 3mA max.  
—Standby current, 500µA max.  
• High reliability  
—Endurance, 100,000 data changes per bit  
—Register data retention, 100 years  
• X9C102 = 1 kΩ  
• X9C103 = 10 kΩ  
• X9C503 = 50 kΩ  
The device can be used as a three-terminal potentiom-  
eter or as a two-terminal variable resistor in a wide  
variety of applications including:  
– control  
• X9C104 = 100 kΩ  
• Packages  
—8-lead SOIC and DIP  
– parameter adjustments  
– signal processing
