FN8182.3  
Low Noise, Low Power, 3 wire Up/Down,  
32 Taps  
Features  
• Solid-state potentiometer  
• Up/Down interface  
• 32 wiper tap points  
The Intersil X93156 is a three-terminal 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 an Up/Down  
interface.  
- Wiper position stored in nonvolatile memory and  
recalled on power-up  
• 31 resistive elements  
The potentiometer is implemented by a resistor array  
composed of 31 resistive elements and a wiper switching  
network. 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 a nonvolatile memory and then be recalled upon  
a subsequent power-up operation.  
- Temperature compensated  
- Maximum resistance tolerance of ±25%  
- Terminal voltage, 0 to V  
CC  
• Low power CMOS  
- VCC = 2.7V to 5.5V  
- Active current, 200µA typ.  
- Standby current, 2µA 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 the programming of bias voltages,  
LCD brightness and contrast control as well as the  
implementation of ladder networks.  
• High reliability  
- Endurance 200,000 data changes per bit  
- Register data retention, 100 years  
• RTOTAL value = 12.5kΩ, 50kΩ  
• Package  
- 8 Ld MSOP  
- Pb-free Available (RoHS compliant)
