Terminal Voltage 0V to +15V, 100 Taps NOT RECOMMENDED FOR NEW DESIGNS Data Sheet March 15, 2005 FN8176.0 NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or Digitally Controlled Potentiometer DESCRIPTION (XDCP™)
The Intersil X9312 is a digitally controlled potentiometer (XDCP). The device consists of a
resistor array, wiper switches, a control section, and
• Solid-state potentiometer
nonvolatile memory. The wiper position is controlled
• 3-wire serial interface
by a 3-wire interface.
• Terminal voltage, 0 to +15V
The potentiometer is implemented by a resistor array
• 100 wiper tap points
composed of 99 resistive elements and a wiper
—Wiper position stored in nonvolatile memory
switching network. Between each element and at
and recalled on power-up
either end are tap points accessible to the wiper
• 99 resistive elements
terminal. The position of the wiper element is
—Temperature compensated
controlled by the CS, U/D, and INC inputs. The
—End to end resistance range ± 20%
position of the wiper can be stored in nonvolatile
• Low power CMOS
memory and then be recalled upon a subsequent
—VCC = 5V
power-up operation.
—Active current, 3mA max. —Standby current, 1mA max.
The device can be used as a three-terminal
• High reliability
potentiometer or as a two-terminal variable resistor in
—Endurance, 100,000 data changes per bit
a wide variety of applications including:
—Register data retention, 100 years
– control
• RTOTAL values = 10k
and 100k

• Packages
– parameter adjustments
—8-lead SOIC and DIP
– signal processing
