FN8160 Rev 3.00 February 3, 2011 X9116 Low Noise, Low Power, Low Cost Digitally Controlled Potentiometer (XDCP™) DATASHEETThe Intersil X9116 is a digitally controlled nonvolatile potentiometer designed to be used in trimmer applications. The pot consists of 15 equal resistor segments that connect to the wiper pin through programmable CMOS switches. The tap position is programmed through a 3-wire up/down serial port. The last position of the wiper is stored in a nonvolatile memory location which is recalled at the time of power up of the device. The wiper moves through sequential tap positions with inputs on the serial port. A falling edge on INC (bar) causes the tap position to increment one position up or down based on whether the U/D (bar) pin is held high or low. The X9116 can be used in many applications requiring a variable resistance. In many cases it can replace a mechanical trimmer and offers many advantages such as temperature and time stability as well as the reliability of a solid state solution. Features • Solid-state nonvolatile • 16 wiper taps • 3-wire up/down serial interface • VCC = 2.7V and 5V • Active current < 50µA max. • Standby current < 5µA max. • RTOTAL = 10k • Packages: 8 Ld MSOP, 8 Ld SOIC • Pb-free plus anneal available (RoHS compliant) Pinout Block Diagram VH/RH VCCINC U/D 1 2 3 4 8 7 6 5 X9116 SOIC/MSOP VSS CS VL/RL VW/RW Control and Memory Up/Down (U/D) Increment (INC) Device Select (CS) VCC (Supply Voltage) VSS (Ground) RH/VH RW/VW RL/VL General RL RH 0 1 2 3 * 13 14 15 RW-RL Resistance 10k 9.34k 8.68k * k 2.08k 1.42k 760 100FN8160 Rev 3.00 Page 1 of 9 February 3, 2011

X9116 Pin Descriptions VH /RH and VL /RL The high (VH/RH) and low (VL/RL) terminals of the X9116 are equivalent to the fixed terminals of a mechanical potentiometer. The minimum voltage is VSS and the maximum is VCC. V W /R W Rw/Rw is the wiper terminal and is equivalent to the movable terminal of a mechanical potentiometer. The position of the wiper within the array is determined by the control inputs. The wiper terminal series resistance is typically 200 to 400 depending upon VCC. Up/Down (U/D) The U/D input controls the direction of the wiper movement and whether the counter is incremented (up) or decremented (down). Increment (INC) The INC input is negative-edge triggered. Toggling INC will move the wiper and either increment or decrement the counter in the direction indicated by the logic level on the U/D input. Chip Select (CS) The device is selected when the CS input is LOW. The current counter value is stored in nonvolatile memory when CS is returned HIGH while the INC input is also HIGH. After the store operation is complete the X9116 will be placed in the low power standby mode until the device is selected once again.

X9116 Principles of Operation There are three sections of the X9116: the input control, counter and decode section; the nonvolatile memory; and the resistor array. The input control section operates just like an up/down counter. The output of this counter is decoded to turn on a single electronic switch connecting a point on the resistor array to the wiper output. Under the proper conditions the contents of the counter can be stored in nonvolatile memory and retained for future use. The resistor array is comprised of 15 individual resistors connected in series. At either end of the array and between each resistor is an electronic switch that transfers the potential at that point to the wiper pin. The wiper, when at either fixed terminal, acts like its mechanical equivalent and does not move beyond the last position. That is, the counter does not wrap around when clocked to either extreme. The electronic switches on the device operate in a “make before break” mode when the wiper changes tap positions. If the wiper is moved several positions, multiple taps are connected to the wiper for tIW (INC to VW change). The RTOTAL value for the device can temporarily be reduced by a significant amount if the wiper is moved several positions. When the device is powered-down, the last wiper position stored will be maintained in the nonvolatile memory. When power is restored, the contents of the memory are recalled and the wiper is set to the value last stored. Instructions and Programming The INC, U/D and CS inputs control the movement of the wiper along the resistor array. With CS set LOW, the device is selected and enabled to respond to the U/D and INC inputs. HIGH to LOW transitions on INC will increment or decrement (depending on the state of the U/D input) a four bit counter. The output of this counter is decoded to select one of 16 wiper positions along the resistive array. The value of the counter is stored in nonvolatile memory whenever CS transitions HIGH while the INC input is also HIGH. The system may select the X9116, move the wiper, and deselect the device without having to store the latest wiper position in nonvolatile memory. After the wiper movement is performed as described above and once the new position is reached, the system must keep INC LOW while taking CS HIGH. The new wiper position will be maintained until changed by the system or until a power-up/down cycle recalls the previously stored data. This procedure allows the system to always power-up to a preset value stored in nonvolatile memory; then during system operation, minor adjustments could be made. The adjustments might be based on user preference, system parameter changes due to temperature drift, etc. The state of U/D may be changed while CS remains LOW. This allows the host system to enable the device and then move the wiper up and down until the proper trim is attained.
