Digitally Controlled Potentiometer (XDCP™), Terminal Voltage ±2.7V to ±5V,
128 Taps, Up/Down Interface
The Intersil ISL95710 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 Up/Down interface.
Features
The potentiometer is implemented by a resistor array
composed of 127 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.
• DCP Terminal Voltage ±2.7V to ±5.5V
The device can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications including:
• Industrial and automotive control
• Parameter and bias adjustments
• Amplifier bias and control
• Non-Volatile Solid-State Potentiometer
• Up/Down Interface with Chip Select Enable
• 128 Wiper Tap Points
- Wiper position stored in nonvolatile memory and
recalled on power-up
• 127 Resistive Elements
- Typical RTOTAL tempco = ±50ppm/°C
- End to end resistance range ±20%
• Low Power CMOS
- Standby current, 1µA
- Active current, 3mA max
- VCC = 2.7V to 5.5V
- V- = -2.7V to -5.5V

Power Up and Down Requirements
RW
In order to prevent unwanted tap position changes, or an
inadvertent store, bring the CS and INC high before or
concurrently with the VCC pin on power-up. The potentiometer
voltages must be applied after this sequence is completed.
During power-up, the data sheet parameters for the DCP do
not fully apply until 1ms after VCC reaches its final value. The
VCC ramp spec is always in effect.
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 wiper counter.
Pin Descriptions
RH and RL
The high (RH) and low (RL) terminals of the ISL95710 are
equivalent to the fixed terminals of a mechanical
potentiometer. The terminology of RL and RH references the
relative position of the terminal in relation to wiper movement
direction selected by the U/D input and not the voltage
potential on the terminal.
FN8240 Rev 3.00
August 31, 2006
Up/Down (U/D)
The U/D input controls the direction of the wiper movement and
whether the wiper counter is incriminated or decremented.
Increment (INC)
The INC input is negative-edge triggered. Toggling INC will
move the wiper and either increment or decrement the wiper
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
wiper 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 ISL95710 will be placed in the
low power standby mode until the device is selected once again.
Page 8 of 10
ISL95710
Principles of Operation
There are three sections of the ISL95710: the input control,
wiper counter and decode section; the nonvolatile memory;
and the resistor array. The input control section operates as an
up/down counter. The output of this wiper counter is decoded
to turn on a electronic switch connecting a point on the resistor
array to the wiper output. The contents of the wiper counter
can be stored in nonvolatile memory and retained for future
use. The resistor array is comprised of 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.
The wiper, when at either fixed terminal, acts like its
mechanical equivalent and does not move beyond the last
position. The wiper 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 RW 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 seven bit wiper
counter. The output of this wiper counter is decoded to select
one of 128 wiper positions along the resistive array.
The system may select the ISL95710, 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. During
initial power-up CS must go high along with or before VCC to
avoid an accidental store generation.
