DATASHEET X9259 FN8169 Rev 6.00 Single Supply/Low Power/256-Tap/2-Wire Bus Quad Digitally-Controlled December 12, 2014 (XDCP) Potentiometers The X9259 integrates four digitally controlled potentiometers Features (XDCP) on a monolithic CMOS integrated circuit. Four separate potentiometers in one package The digitally controlled potentiometers are implemented with 256 resistor taps0.4% resolution a combination of resistor elements and CMOS switches. The position of the wipers are controlled by the user through the 2-wire serial interface for write, read, and 2-wire bus interface. Each potentiometer has associated with transfer operations of the potentiometer it a volatile Wiper Counter Register (WCR) and four nonvolatile Wiper resistance: 100 typical at V = 5V CC Data Registers that can be directly written to and read by the 4 nonvolatile data registers for each potentiometer user. The content of the WCR controls the position of the wiper. At power-up, the device recalls the content of the default Data Nonvolatile storage of multiple wiper positions Registers of each DCP (DR00, DR10, DR20, and DR30) to the Standby current <5A max corresponding WCR. V : 2.7V to 5.5V operation CC The XDCP can be used as a three-terminal potentiometer or as 50k version of total resistance a two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and Endurance: 100,000 data changes per bit per register signal processing. 100 year data retention Single supply version of X9258 24 Ld SOIC, 24 Ld TSSOP Low power CMOS Pb-Free (RoHS compliant) Functional Diagram R R R R V CC H0 H1 H2 H3 DCP0 DCP1 DCP2 DCP3 WCR0 WCR1 WCR2 WCR3 A3 DR00 DR10 DR20 DR30 2-WIRE DR01 DR11 DR21 DR31 INTERFACE A2 POWER UP, DR02 DR12 DR22 DR32 INTERFACE DR03 DR13 DR23 DR33 A1 CONTROL AND STATUS A0 SDA SCL V R R SS WP R R R R R R L0 L1 L2 L3 W0 W1 W2 W3 FN8169 Rev 6.00 Page 1 of 21 December 12, 2014X9259 Ordering Information PART NUMBER PART V LIMITS R TEMP RANGE PACKAGE PKG.
