Product details
Overview
X93256WV14I-2.7 from Intersil is a dual digitally controlled potentiometer (XDCP™) implementing two independent 32-tap, nonvolatile resistor arrays with 12.5kΩ end-to-end resistance, operating from 2.7V to 5.5V supply and supporting bias/gain control in LCD contrast circuits.
For engineers reviewing the X93256WV14I-2.7 datasheet, X93256WV14I-2.7 pinout, X93256WV14I-2.7 application, or X93256WV14I-2.7 equivalent, key selection criteria include wiper position retention after power cycle, individual Up/Down interface control per potentiometer, ±25% RTOTAL tolerance, and TSSOP-14 package compatibility with industrial temperature range (-40°C to +85°C).
Technical Context
The X93256WV14I-2.7 integrates two independent 5-bit up/down counters driving 31-resistor arrays, each with dedicated CS1/CS2, U/D1/U/D2, and INC1/INC2 control lines. Wiper positions are stored in EEPROM and recalled at power-up without external intervention.
Each potentiometer functions as a three-terminal variable resistor with RH/RL terminals spanning 0–VCC, RW wiper output, and temperature-compensated resistance (±35 ppm/°C). Standby current is ≤4 µA per potentiometer, and active current is 200 µA typical at VCC = 3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 12.5 kΩ ±25% - defines full-scale resistance range for analog trimming accuracy and voltage-divider ratio stability |
| Supply Voltage | 2.7V to 5.5V - supports single-supply operation across industrial logic families including 3.3V and 5V systems |
| Resolution | 32 taps (5-bit) - enables discrete stepwise adjustment of gain/bias with ~3% step resolution relative to RTOTAL |
| Wiper Resistance | 1100 Ω max - limits signal path error and loading effect when used in high-impedance feedback networks |
| Nonvolatile Storage | 100-year data retention, 200,000 write cycles - ensures factory-set or user-trimmed values persist over product lifetime |
| Operating Temp | -40°C to +85°C - qualified for industrial environments without derating or external thermal management |
| Power Consumption | 200 µA active / 4 µA standby per pot - enables low-power trimming in battery-backed or energy-sensitive systems |
Pinout & Package

| RL2 | Low-side fixed terminal, Potentiometer 2 | Ground-referenced end of second resistor array; matches RL1 functionality |
| CS2 | Chip select input, Potentiometer 2 | Active-low enable for second pot; independent storage and control from CS1 |
| VCC | Positive supply | Power source for logic, memory, and resistor array; must exceed RH/RL voltages per absolute max rating |
| INC1 | Increment clock, Potentiometer 1 | Negative-edge-triggered; controls wiper position of first potentiometer |
| U/D1 | Direction control, Potentiometer 1 | Determines increment/decrement behavior of first potentiometer counter |

Key Features
| Feature | Design Value |
|---|---|
| Dual independent XDCPs | Two fully isolated 12.5kΩ potentiometers with separate control interfaces eliminate cross-talk in multi-channel trimming |
| Nonvolatile wiper recall | Automatically restores last-stored wiper positions at power-up-no host initialization required for preset operation |

| Temperature-compensated array | ±35 ppm/°C RTOTAL drift maintains trim accuracy across -40°C to +85°C without calibration software |
| Low-power standby mode | 4 µA max per potentiometer in standby reduces system quiescent current during idle periods |
Applications
| LCD Contrast Control | Op-Amp Gain Adjustment |
|---|---|
|
Use Scenario: Adjusting contrast voltage in character or graphic LCD modules powered by 3.3V or 5V rails. IC Role / Device Role / Timing Role: Acts as digitally programmable voltage divider between VCC and VSS to set VLCD reference level. Use Value: Enables factory calibration and user-adjustable contrast without mechanical pots; retains setting across power cycles. |
Use Scenario: Setting closed-loop gain in instrumentation amplifiers or programmable-gain transimpedance stages. IC Role / Device Role / Timing Role: Replaces manual trimmer in feedback path; wiper position defines Rf/Rin ratio for precision DC gain control. Use Value: Provides stable, repeatable gain values immune to vibration or environmental drift; supports remote recalibration. |
| Bias Current Trimming | Audio Volume Control |
|
Use Scenario: Calibrating reference currents in voltage regulators, LED drivers, or sensor front-ends. IC Role / Device Role / Timing Role: Serves as adjustable current-setting resistor in constant-current source configurations. Use Value: Achieves <±2% initial bias accuracy using 32-step resolution and eliminates manual calibration labor. |
Use Scenario: Implementing mono or stereo analog volume control in embedded audio subsystems. IC Role / Device Role / Timing Role: Functions as two independent attenuators-one per channel-with simultaneous or staggered adjustment. Use Value: Delivers click-free attenuation via monotonic wiper stepping and avoids mechanical wear or contact noise. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5242BRUZ10 | Single 10kΩ pot, I²C interface, 256 taps; no nonvolatile recall on power-up unless externally managed | Requires microcontroller firmware to reload settings; unsuitable for standalone power-cycle restoration | Select when I²C bus integration and higher resolution outweigh need for autonomous recall |
| MCP42010-I/P | Dual 10kΩ pot, SPI interface, volatile wiper only; no EEPROM storage | Needs continuous host refresh; cannot retain settings without external memory or controller supervision | Choose for cost-sensitive, controller-managed trimming where EEPROM is unnecessary |
Compared with AD5242BRUZ10 and MCP42010-I/P, the X93256WV14I-2.7 uniquely delivers autonomous power-up wiper recall, dual independent Up/Down interfaces, and guaranteed 12.5kΩ RTOTAL tolerance-making it optimal for unattended industrial trim applications requiring zero-host dependency.

FAQ
What is the end-to-end resistance value of the X93256WV14I-2.7?
The X93256WV14I-2.7 has an RTOTAL of 12.5 kΩ ±25%, confirmed in the datasheet's Potentiometer Characteristics table under the "W option" row. This value applies to both integrated potentiometers and defines the maximum resistance between RH and RL terminals for each array.
Does the X93256WV14I-2.7 retain wiper positions after power loss?
Yes, the X93256WV14I-2.7 stores wiper positions in nonvolatile EEPROM memory. Upon power-up, both potentiometers automatically recall their last-stored positions-no external controller or initialization sequence is needed for this behavior in the X93256WV14I-2.7.
What supply voltage range does the X93256WV14I-2.7 support?
The X93256WV14I-2.7 operates from 2.7V to 5.5V, as specified in the Recommended Operating Conditions section. This range accommodates both 3.3V and 5V logic systems and remains valid across the full -40°C to +85°C industrial temperature range.
How many wiper positions does each potentiometer in the X93256WV14I-2.7 offer?
Each potentiometer in the X93256WV14I-2.7 provides 32 discrete wiper positions, implemented via a 5-bit up/down counter driving a 31-element resistor ladder. This yields 31 resistive segments and 32 tap points-including both RH and RL endpoints.
Is the X93256WV14I-2.7 available in a RoHS-compliant package?
Yes, the X93256WV14I-2.7 is supplied in a standard 14-lead TSSOP package compliant with RoHS Directive 2011/65/EU. A Pb-free variant (X93256WV14IZ-2.7) is also offered with identical electrical specifications and MSL3 reflow compatibility.
