X9313 Terminal Voltages ±5V, 32 Taps Digitally Controlled Potentiometer (XDCP™) The Intersil X9313 is a 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 a 3-wire interface. The potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching 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. The device 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 • Signal processing Features • Solid-state potentiometer • 3-wire serial interface • 32 wiper tap points - Wiper position stored in nonvolatile memory and recalled on power-up • 31 resistive elements - Temperature compensated - End to end resistance range ± 20% - Terminal voltages, -5V to +5V • Low power CMOS -VCC = 3V or 5V - Active current, 3mA max. - Standby current, 500µA max. • High reliability - Endurance, 100,000 data changes per bit - Register data retention, 100 years •RTOTAL values = 1kΩ, 10kΩ, 50kΩ • Packages - 8 Ld SOIC, MSOP and DIP • Pb-free plus anneal available (RoHS compliant) Block Diagrams 5-BIT NONVOLATILE MEMORY STORE AND RECALL CONTROL CIRCUITRY ONE OF DECODER RESISTOR ARRAY RH/VH U/D INC CS TRANSFER GATES THIRTY VCC VSS RL/VL RW/VW CONTROL UP/DOWN VCC (SUPPLY VOLTAGE) VSS (GROUND) RH/VH RW/VW RL/VL GENERAL DETAILED 0 1 2 28 29 30 31 TWO (U/D) INCREMENT (INC) DEVICE SELECT (CS) AND MEMORY 5-BIT UP/DOWN COUNTER Data Sheet September 9, 2005 |
