DATASHEET X9119 FN8162 Rev 5.00 1024 Tap, Low Power, 2-Wire Interface, Digitally Controlled (XDCP) July 5, 2016 Potentiometer The X9119 integrates a single digitally controlled Features potentiometer (XDCP) on a monolithic CMOS integrated 1024 resistor taps 10-bit resolution circuit. 2-Wire serial interface for write, read, and The digital controlled potentiometer is implemented using transfer operations of the potentiometer 1023 resistive elements in a series array. Between each element are tap points connected to the wiper terminal Wiper resistance, 40 typical at V = 5V CC through switches. The position of the wiper on the array is Four nonvolatile data registers controlled by the user through the 2-wire bus interface. The potentiometer has associated with it a volatile Wiper Counter Nonvolatile storage of multiple wiper positions Register (WCR) and four nonvolatile data registers that can be Power-on recall, loads saved wiper position on power-up. directly written to and read by the user. The contents of the WCR controls the position of the wiper on the resistor array Standby current <3A maximum through the switches. Power-up recalls the contents of the V : 2.7V to 5.5V operation CC default data register (DR0) to the WCR. 100k end-to-end resistance The XDCP can be used as a 3-terminal potentiometer or as a 100 yr. data retention 2-terminal variable resistor in a wide variety of applications including control, parameter adjustments and signal Endurance: 100,000 data changes per bit per register processing. 14 Ld TSSOP Low power CMOS Single supply version of the X9118 Pb-free available (RoHS compliant) V R CC H WRITE ADDRESS POWER-ON RECALL READ 100k DATA TRANSFER 1024-TAPS STATUS BUS WIPER COUNTER 2-WIRE POT REGISTER (WCR) INTERFACE BUS AND WIPER INTERFACE DATA REGISTERS CONTROL (DR0-DR3) CONTROL R V NC NC R W L SS FIGURE 1.
