DATASHEET
Single Supply/Low Power/256-Tap/2-Wire Bus Quad
Digitally-Controlled (XDCP™) Potentiometers
X9259
The X9259 integrates four digitally controlled potentiometers
(XDCP) on a monolithic CMOS integrated circuit.
The digitally controlled potentiometers are implemented with
a combination of resistor elements and CMOS switches. The
position of the wipers are controlled by the user through the
2-wire bus interface. Each potentiometer has associated with
it a volatile Wiper Counter Register (WCR) and four nonvolatile
Data Registers that can be directly written to and read by the
user. The content of the WCR controls the position of the wiper.
At power-up, the device recalls the content of the default Data
Registers of each DCP (DR00, DR10, DR20, and DR30) to the
corresponding 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.
Features
• Four separate potentiometers in one package
• 256 resistor taps–0.4% resolution
• 2-wire serial interface for write, read, and
transfer operations of the potentiometer
• Wiper resistance: 100Ω typical at V
CC
= 5V
• 4 nonvolatile data registers for each potentiometer
• Nonvolatile storage of multiple wiper positions
• Standby current <5µA max
•V
CC
: 2.7V to 5.5V operation
• 50kΩ version of total resistance
• Endurance: 100,000 data changes per bit per register
• 100 year data retention
• Single supply version of X9258
• 24 Ld SOIC, 24 Ld TSSOP
•Low power CMOS
• Pb-Free (RoHS compliant)

NOTES:
1. Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
2. Add "T1" suffix for tape and reel.
3. For Moisture Sensitivity Level (MSL), please see product information page for X9259
. For more information on MSL, please see tech brief TB363.
