Product details
Overview
X9C104S from Renesas Electronics is a digitally controlled potentiometer (XDCP™) with 100-kΩ end-to-end resistance, 100 wiper tap points, nonvolatile wiper position storage, ±5 V terminal voltage rating, and 8-lead SOIC package. It functions as a solid-state three-terminal potentiometer or two-terminal variable resistor in analog signal trimming, power supply feedback adjustment, and programmable gain control circuits.
For engineers reviewing the X9C104S datasheet, X9C104S pinout, X9C104S application, or X9C104S equivalent, this page delivers verified specifications, validated pin functions, confirmed operating conditions (0°C to +70°C), real-world use cases, and two technically documented alternative parts for design flexibility.
Technical Context
The X9C104S implements a 99-resistor-element array with make-before-break wiper switching, controlled via a three-wire serial interface (CS, U/D, INC) using negative-edge-triggered increment logic. Its 7-bit up/down counter drives a decoder selecting one of 100 wiper positions, with position stored in nonvolatile memory on CS↑/INC↑ transition.
It features temperature-compensated resistor elements (±300 ppm/°C RTOTAL TC), 40 Ω typical wiper resistance, ±5 V terminal voltage range, and low-power CMOS operation at 5 V ±10%, drawing ≤3 mA active current and ≤750 µA standby current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 100 kΩ ±20% - defines full-scale analog adjustment range and load interaction in voltage divider or current-limiting configurations |
| Wiper Tap Points | 100 positions - enables 1% resolution per step for precise calibration without mechanical wear |
| Terminal Voltage Range | ±5 V referenced to VSS - supports bipolar signal conditioning and rail-to-rail operation within single 5 V supply |
| Nonvolatile Storage | 100-year data retention - ensures power-up repeatability without external EEPROM or initialization firmware |
| Supply Voltage | 5 V ±10% - compatible with standard TTL/CMOS logic rails and eliminates need for auxiliary bias supplies |
| Wiper Resistance | 40 Ω typical - limits insertion error in low-impedance feedback paths and maintains linearity under load |
| Operating Temperature | 0°C to +70°C - certified for commercial-grade embedded systems including consumer electronics and industrial HMIs |
Pinout & Package
Package: 8-lead narrow-body SOIC (M8.15E footprint), RoHS-compliant, surface-mount, 1.27 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INC | Increment clock input | Negative-edge-triggered control signal; toggling moves wiper one position in direction set by U/D |
| 2 U/D | Up/Down direction control | Logic level determines wiper movement direction (HIGH = increment, LOW = decrement) during INC edge |
| 3 VH/RH | High-side fixed terminal | One end of resistor array; rated for −5 V to +5 V; polarity label reflects wiper motion direction, not voltage potential |
| 4 VSS | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise-sensitive analog operation |
| 5 VW/RW | Wiper output terminal | Movable contact point; series resistance ~40 Ω; connects to selected tap via electronic switch network |
| 6 VL/RL | Low-side fixed terminal | Opposite end of resistor array; rated for −5 V to +5 V; labeling relative to U/D state, not absolute voltage |
| 7 CS | Chip select | Active-low enable; wiper position stored to NV memory when CS transitions HIGH while INC is HIGH |
| 8 VCC | Positive supply | 5 V ±10% input; powers internal logic, charge pump, and wiper switches; ramp rate must be 0.2–50 V/ms |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, contact bounce, and vibration sensitivity-enables >100,000 wiper adjustments over lifetime |
| Three-wire serial interface | Requires only CS, U/D, and INC signals-minimizes MCU GPIO usage and avoids SPI/I²C protocol overhead |
| Nonvolatile wiper recall | Automatically restores last-stored position at power-up-removes need for boot-time calibration or host initialization |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift-maintains stable resistance ratio across 0°C to +70°C, critical for precision feedback loops |
| Charge pump support | Enables ±5 V analog signal swing from single 5 V supply-simplifies system-level power architecture |
Applications
| Audio Volume Control | Power Supply Feedback Trim |
|---|---|
Use Scenario: Digital volume adjustment in headphone amplifiers or line-level audio processors. IC Role / Device Role / Timing Role: Two-terminal variable resistor replacing mechanical potentiometer in gain-setting feedback path of op-amp stage. Use Value: Enables silent, glitch-free channel balancing via software; retains user-set volume after power cycle without MCU intervention. |

IC Role / Device Role / Timing Role: Three-terminal potentiometer in summing junction of op-amp-based offset correction circuit. Use Value: Delivers <1% resolution (100 taps) for sub-mV offset tuning; nonvolatile storage preserves calibration across maintenance cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5204BRZ100 | Quad-channel, 100 kΩ, SPI interface, 256-tap resolution, ±30% RTOTAL tolerance | Supports simultaneous multi-channel adjustment; higher resolution but wider resistance tolerance | Select when multiple independent potentiometers are needed on one chip and SPI is preferred over 3-wire logic |
| MCP41010-I/P | Single-channel, 10 kΩ nominal, SPI interface, 257-tap resolution, volatile wiper register only | Requires external MCU to reload wiper value at startup; no nonvolatile storage | Select when cost-sensitive designs can tolerate recalibration at power-on and higher resolution outweighs NV requirement |
Compared with AD5204BRZ100 and MCP41010-I/P, the X9C104S offers guaranteed nonvolatile recall, simpler 3-wire control, and tighter ±20% end-to-end resistance tolerance-making it optimal for single-channel, self-initializing analog trim where reliability and minimal firmware overhead are prioritized.

FAQ
What is the maximum allowable voltage across VH/RH and VL/RL terminals for the X9C104S?
The X9C104S supports a maximum differential voltage of 10 V between VH/RH and VL/RL terminals. This rating applies specifically to the X9C104S (100 kΩ variant); lower-resistance variants like X9C102 have stricter 4 V limits. Exceeding 10 V risks permanent damage to the internal resistor array or switching network.
Does the X9C104S retain its wiper position after power loss?
Yes, the X9C104S stores the current wiper position in nonvolatile memory upon a valid store command (CS↑ while INC is HIGH). That value is automatically recalled during the next power-up sequence once VCC reaches its final regulated value, ensuring consistent startup behavior without host MCU involvement.
Can the X9C104S operate with a 3.3 V supply instead of 5 V?
No-the X9C104S is specified only for 5 V ±10% operation (4.5 V to 5.5 V). Its internal charge pump, logic thresholds, and wiper switch drive depend on nominal 5 V supply. Operation outside this range may cause unreliable wiper movement, failed NV storage, or increased wiper resistance variation.
What is the typical wiper resistance of the X9C104S and how does it affect circuit accuracy?
The X9C104S has a typical wiper resistance of 40 Ω, with a maximum of 100 Ω. In low-impedance feedback networks (e.g., <10 kΩ), this series resistance introduces gain error and temperature-dependent drift. Designers should account for it in precision applications-especially when VW/RW drives high-current loads or low-input-impedance stages.
How many wiper position changes can the X9C104S endure before failure?
The X9C104S guarantees 100,000 wiper position changes per bit in nonvolatile memory. This endurance rating reflects write cycles to the NV register-not total wiper movements. Frequent wiper adjustments without storing to NV memory do not consume endurance cycles, enabling unlimited runtime repositioning during active operation.
