ISL22511
Low Noise, Low Power, 32 Taps, Up/Down, Single Push-Button Controlled Potentiometer (XDCP™)
Features
The ISL22511 is a three-terminal digitally-controlled
potentiometer (XDCP) implemented by a resistor
array composed of 31 resistive elements and a wiper
switching network. The ISL22511 features a
push-button control, a Shutdown mode, and an
industry-leading UTQFN package.
• Solid-state non-volatile potentiometer
• Push button controlled
• Single or auto increment/decrement
○ Fast mode after 1s button press
The push-button control has individual PU and PD
inputs for adjusting the wiper. To eliminate
redundancy, the wiper position automatically
increments or decrements if one of these inputs is
held longer than one second.
• AUTOSTORE of last wiper position or manual store
of wiper position
• Shutdown mode
• 32 wiper tap points
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 to minimize power
consumption.
○ Max scale wiper position on power-up
• Low power CMOS
○ VCC = 2.7V to 5.5V
○ Terminal voltage, 0V to VCC
The three terminals accessing the resistor chain
naturally configure the ISL22511 as a voltage divider.
A rheostat is easily formed by floating an end terminal
or connecting it to the wiper.
○ Standby current, 3µA max
• RTOTAL value = 10kΩ
• High reliability
○ Endurance: 1000000 data changes per bit per
register

Description
1
PU
Falling-edge triggered input with internal pull-up. Toggle PU to move the wiper close to the RH terminal. The
debounced PU input increments the wiper position. An on-chip pull-up holds the PU input HIGH. A switch closure to
ground or a LOW logic level moves the wiper to the next adjacent higher tap position after a debounce time.
2
PD
Falling-edge triggered input with internal pull-up. Toggle PD to move the wiper close to the RL terminal. The
debounced PD input decrements the wiper position. An on-chip pull-up holds the PD input HIGH. A switch closure
to ground or a LOW logic level moves the wiper to the next adjacent lower tap position after a debounce time.
3
RH
The RH and RL pins are equivalent to the fixed terminals of a mechanical potentiometer. The minimum voltage is
VSS and the maximum voltage is VCC. The terms RH and RL refer to the relative position of the terminal in relation
to the wiper movement direction selected by the PU/PD input.
4
VSS

6
RW
Wiper terminal of the potentiometer, which is equivalent to the movable terminal of a mechanical potentiometer.
7
RL
The RH and RL pins are equivalent to the fixed terminals of a mechanical potentiometer. The minimum voltage is
VSS and the maximum voltage is VCC. The terms RH and RL refer to the relative position of the terminal in relation
to the wiper movement direction selected by the PU/PD input.
8
ASE
Active low AUTOSTORE enable input or Manual Store active low input. The debounced ASE pin can be in one of
two states:
• AUTOSTORE is enabled if ASE is held LOW during power up.
• AUTOSTORE is disabled if ASE is held HIGH during power-up. A LOW to HIGH transition initiates a manual
store operation to enable connection of a push-button switch to this pin. For every valid push, the ISL22511
stores the current wiper position to the EEPROM.

Notes:
6. Typical values are for TA = +25°C and 3.3V supply voltage.
7. LSB: [V(RW)31 – V(RW)0]/31. V(RW)31 and V(RW)0 are the voltage on the RW pin for the DCP register set to 1F hex and 00 hex,
respectively. LSB is the incremental voltage when changing from one tap to an adjacent tap.
8. ZS error = V(RW)0/LSB.
9. FS error = [V(RW)31 – VCC]/LSB.
10. DNL = [V(RW)i – V(RW)i-1]/LSB -1, for i = 1 to 31; i is the DCP register setting.
11. INL = [V(RW)i – i • LSB – V(RW)]/LSB for i = 1 to 31
12. See Equation 1.
(EQ. 1)

TC V = --------------------------------------------------------------------------------------------- ------------------- Max V RW i + Min V RW i 2 +165°C
for i = 5 to 31 decimal, T = -40°C to +125°C. Max ( ) is the maximum value of the wiper voltage and Min ( ) is the minimum value of the
wiper voltage over the temperature range.
13. MI = |RW31 – RW0|/31. MI is a minimum increment. RW31 and RW0 are the measured resistances for the DCP register set to 1F hex and
00 hex, respectively.
14. Roffset = RW0/MI when measuring between RW and RL.
Roffset = RW31/MI when measuring between RW and RH.
15. RDNL = (RWi – RWi-1)/MI for i = 1 to 31.
16. RINL = [RWi – (MI • i) – RW0]/MI for i = 1 to 31.

Device Overview
Power-Up and Power-Down Requirements
There are no restrictions on the power-up or power-down conditions of VCC and the voltages applied to the
potentiometer pins if VCC is always more positive than or equal to VRH and VRL, (VCC VRH,VRL). The VCC ramp
rate specification is always in effect.
5.2
Operating the Device
The ISL22511 consists of three sections:
• Input control, counter, and decode section
• EEPROM memory
• 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 and connects a point on the resistor array to the wiper output. Under the proper
conditions, the contents of the counter can be stored in EEPROM memory and retained for future use. The
resistor array is comprised of 31 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.
Note: The ISL22511 is programmed from the factory with the wiper set to the highest position: 0x1Fh.
The ISL22511 interfaces directly to two push-button switches to effectively move the wiper up or down. The PU
input increments a 5-bit counter and the PD input decrements a 5-bit counter. The output of this counter is
decoded to select one of the 32 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 is switched to the next
adjacent tap position.
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 multiple increments/decrements. The number of increments/decrements of the wiper position
depends on how long the button is pushed. When making a continuous push, the increment/decrement speed
increases after the first second. The device is in Slow Scan mode for the first second. If the button is held for
longer than one second, the device goes into Fast Scan mode. The ISL22511 returns to the standby condition as
soon as the button is released.
If two or more buttons are pressed simultaneously, all commands are ignored upon release of ALL buttons, except
the Shutdown mode condition.
When the wiper is at either fixed terminal, it 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.
5.3
AUTOSTORE
The counter value is stored in EEPROM memory after two seconds of no activity on the 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.
If AUTOSTORE is implemented, ASE is typically hard-wired to VSS. If ASE is held HIGH during power-up and
then taken LOW, the wiper does not respond to the PU or PD inputs until ASE is brought HIGH and held HIGH.

5. Device Overview
Manual (Push Button) Store
When ASE is not enabled (held HIGH), a push-button switch can be used to pull ASE LOW for more than 15ms
and released to perform a manual store of the wiper position.
Note: If ASE is pulled LOW while either the PU or PD inputs are held LOW continuously, no store to the EEPROM
occurs.
During memory write cycles, all inputs are ignored.
5.5
Shutdown Mode
The ISL22511 enters Shutdown mode if both the PU and PD inputs are kept LOW for two seconds. In Shutdown
mode, the resistors array is totally disconnected from its RH pin and the wiper is moved to the position closest to
the RL pin, as shown in Figure 19.
Note: The PU and PD inputs must be pulled LOW within the tDB time window of 15ms, otherwise, all commands
are ignored until both inputs are released. See “Shutdown Mode Timing” on page 7 for more information.

Figure 19. DCP Connection in Shutdown Mode
Holding either the PU, PD, or ASE input LOW for more than 15ms causes the ISL22511 to exit Shutdown mode
and return the wiper to the prior shutdown position. If PU or PD are held LOW for more than 250ms, the ISL22511
starts auto-incrementing or auto-decrementing the wiper position.
