Low Noise, Low Power, 16 Taps, Push
Button Controlled Potentiometer
Features
• Solid-State Non-Volatile Potentiometer
• Push Button Controlled
The Intersil ISL22512 is a three-terminal digitally-controlled
potentiometer (XDCP) implemented by a resistor array
composed of 15 resistive elements and a wiper switching
network. The ISL22512 features a push button control, a
shutdown mode, as well as an industry-leading µTQFN
package.
• Single or Auto Increment/Decrement
- Fast Mode after 1s Button Press
• AUTOSTORE of Last Wiper Position or Manual Store of
Wiper Position
The push button control has individual PU and PD inputs for
adjusting the wiper. To eliminate redundancy, the wiper
position will automatically increment or decrement if one of
these inputs is held longer than one second.
• Shutdown Mode
• 16 Wiper Tap Points
- Middle Scale Wiper Position on Power-Up
• Low Power CMOS
- VCC = 2.7V to 5.5V
Forcing both PU and PD low for more than two seconds
activates shutdown mode. Shutdown mode disconnects the
top of the resistor chain and moves the wiper to the lowest
position, minimizing power consumption.
- Terminal Voltage, 0 to V
CC
- Standby Current, 3µA max
• RTOTAL Value = 10kΩ
The three terminals accessing the resistor chain naturally
configure the ISL22512 as a voltage divider. A rheostat is
easily formed by floating an end terminal or connecting it to
the wiper.

ISL22512
array is comprised of 15 individual resistors connected in
Power-Up and Down Requirements
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.
There are no restrictions on the power-up or power-down
conditions of VCC and the voltages applied to the
potentiometer pins provided that VCC is always more
positive than or equal to VRH and VRL, i.e., VCC ≥ VRH,VRL
The VCC ramp rate specification is always in effect.
.
The ISL22512 is designed to interface directly to two push
button switches for effectively moving the wiper up or down.
The PU and PD inputs increment or decrement a 4-bit
counter respectively. The output of this counter is decoded to
select one of the thirty-two wiper positions along the resistive
array. The wiper increment input, PU and the wiper
decrement input, PD are both connected to an internal
pull-up so that they normally remain HIGH. When pulled
LOW by an external push button switch or a logic LOW level
input, the wiper will be switched to the next adjacent tap
position.
Pin Descriptions
RH and RL
The RH and RL pins of the ISL22512 are equivalent to the
fixed terminals of a mechanical potentiometer. The minimum
voltage is V and the maximum is V . The terminology of
SS
CC
RH and RL references the relative position of the terminal in
relation to wiper movement direction.
RW
Internal debounce circuitry prevents inadvertent switching of
the wiper position if PU or PD remain LOW for less than
15ms, typical. Each of the buttons can be pushed either
once for a single increment/decrement or continuously for a
multiple increments/decrements. The number of
increments/decrements of the wiper position depends on
how long the button is being pushed. When making a
continuous push, after the first second, the
increment/decrement speed increases. For the first second,
the device will be in the slow scan mode. Then, if the button
is held for longer than 1 second, the device will go into the
fast scan mode. As soon as the button is released, the
ISL22512 will return to a standby condition.
The RW pin is the wiper terminal of the potentiometer which
is equivalent to the movable terminal of a mechanical
potentiometer.
PU
The debounced PU input is used to increment the wiper
position. An on-chip pull-up holds the PU input HIGH. A
switch closure to ground or a LOW logic level will, after a
debounce time, move the wiper to the next adjacent higher
tap position.
PD
The debounced PD input is used to decrement the wiper
position. An on-chip pull-up holds the PD input HIGH. A
switch closure to ground or a LOW logic level will, after a
debounce time, move the wiper to the next adjacent lower
tap position.
If two or more buttons are pressed simultaneously, all
commands are ignored upon release of ALL buttons, except
Shutdown Mode condition.
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.
ASE
The debounced ASE (AUTOSTORE enable) pin can be in
one of two states:
AUTOSTORE
1. AUTOSTORE is enabled if ASE is held LOW during
power-up.
The value of the counter is stored in EEPROM memory after
2 seconds of no activity on PU or PD inputs while ASE is
enabled (held LOW). When power is restored, the content of
the memory is recalled and the counter resets to the last
value stored.
2. AUTOSTORE is disabled if ASE is held HIGH during
power-up. A LOW to HIGH transition will initiate a manual
store operation. This is for the user who wishes to
connect a push button switch to this pin. For every valid
push, the ISL22512 will store the current wiper position to
the EEPROM.
If AUTOSTORE is to be implemented, ASE is typically hard
wired to VSS. If ASE is held HIGH during power-up and then
taken LOW, the wiper will not respond to the PU or PD inputs
until ASE is brought HIGH and held HIGH.
Device Operation
There are three sections of the ISL22512: the input control,
counter and decode section; the EEPROM 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
Manual (Push Button) Store

Shutdown Mode
The ISL22512 enters into Shutdown Mode if both PU and
PD inputs are kept LOW for 2 seconds. In this mode, the
resistors array is totally disconnected from its RH pin and the
wiper is moved to position closest to RL pin, as shown in
Figure 13. Note, that PU and PD inputs must be pulled LOW
within tDB time window of 15ms, see “Shutdown Mode
Timing” on page 5. Otherwise all command will be ignored till
both inputs will be released.

FIGURE 13. DCP CONNECTION IN SHUTDOWN MODE
Holding either PU , PD or ASE input LOW for more than
15ms will exit shutdown mode and return wiper to prior
shutdown position. If PU or PD will be held LOW for more
than 250ms, the ISL22512 will start auto-increment or
auto-decrement of wiper position.
