Product details
Overview
X9C102P from Renesas Electronics is a digitally controlled potentiometer (XDCP™) implementing a 1 kΩ end-to-end resistance resistor array with 99 elements and 100 wiper tap points. It features nonvolatile memory for wiper position storage and recall on power-up, operates from a single 5 V supply, and uses a three-wire serial interface (CS, U/D, INC) for wiper control. It serves as a solid-state replacement for mechanical potentiometers in precision analog trimming applications such as DC bias adjustment in op-amp circuits.
For engineers reviewing the X9C102P datasheet, X9C102P pinout, X9C102P application, or X9C102P equivalent, this page delivers verified technical context, confirmed pin functions, real-world use scenarios, and validated alternative options - all grounded in Renesas FN8222 Rev 4.00 documentation and official ordering data for X9C102PZ.
Technical Context
The X9C102P integrates a 7-bit up/down counter, nonvolatile memory, and a 99-element resistor array with make-before-break wiper switching. Its wiper position is updated on negative-edge transitions of the INC input, directionally controlled by the U/D signal, and latched into memory when CS rises while INC is high.
It supports both three-terminal potentiometer and two-terminal variable resistor configurations. Terminal voltage range is ±5 V, wiper series resistance is typically 40 Ω, and absolute linearity is ±1 MI (±1% of RTOTAL), with ratiometric temperature coefficient of ±20 ppm/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 1 kΩ ±20% - defines full-scale analog range for voltage divider or current-limiting use |
| Wiper Tap Points | 100 positions - enables 1% resolution steps across full resistance range |
| Supply Voltage | 5 V ±10% - single-rail operation compatible with standard logic systems |
| Active Current | ≤3 mA - low power draw during wiper adjustment sequences |
| Standby Current | ≤750 µA - enables energy-efficient retention between adjustments |
| Nonvolatile Storage | 100-year data retention - preserves last-set wiper position across power cycles without backup power |
| Terminal Voltage Range | −5 V to +5 V - supports bipolar analog signal conditioning without external level-shifting |
Pinout & Package
Package: 8-lead PDIP (Plastic Dual-In-Line Package), RoHS-compliant, MDP0031 outline, through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - INC | Increment clock input | Negative-edge-triggered control signal; toggling moves wiper one step in U/D-defined direction |
| 2 - U/D | Direction control input | Logic level sets wiper movement direction (up or down) during each INC transition |
| 3 - VH/RH | High-side fixed terminal | One end of resistor array; accepts −5 V to +5 V; polarity label reflects wiper motion direction, not voltage potential |
| 4 - VSS | Ground reference | System ground connection for internal logic and charge pump circuitry |
| 5 - VW/RW | Wiper output terminal | Movable contact point; series resistance ≈40 Ω; outputs interpolated voltage between RH and RL |
| 6 - VL/RL | Low-side fixed terminal | Opposite end of resistor array; accepts −5 V to +5 V; labeling relative to U/D state, not voltage polarity |
| 7 - CS | Chip select input | Active-low enable; rising edge with INC = HIGH stores current wiper position to nonvolatile memory |
| 8 - VCC | Power supply | +5 V ±10% supply for logic, memory, and internal charge pump operation |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, enabling >100,000 wiper position changes per bit - critical for automated calibration systems |
| Three-wire serial interface | Minimal GPIO footprint (CS, U/D, INC); no clock or data lines required beyond basic control signals |
| Nonvolatile wiper storage | Recalls last position at power-on - ensures repeatable startup behavior without host MCU initialization |

| Charge pump support | Enables ±5 V terminal swing from single 5 V rail - simplifies bipolar analog front-end design |
Applications
| Audio Signal Level Control | DC Bias Adjustment in Op-Amp Circuits |
|---|---|
|
Use Scenario: Programmable gain control in line-level audio preamplifiers where manual trim pots are impractical due to enclosure access constraints. IC Role / Device Role / Timing Role: Two-terminal variable resistor setting feedback network impedance to adjust closed-loop gain of an inverting amplifier stage. Use Value: Enables remote or firmware-controlled volume/gain tuning without hardware modification; retains user-selected level after power cycle. |

Use Scenario: Setting constant-current drive level for high-brightness LEDs in architectural lighting controllers with dimming profiles. IC Role / Device Role / Timing Role: Two-terminal variable resistor in series with LED string to define peak current via sense resistor voltage drop. Use Value: Supports per-unit brightness matching during production; avoids binning costs while maintaining thermal stability over 0–70°C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5201BRMZ-10 | 10 kΩ end-to-end resistance; I²C interface; 64-step resolution; no nonvolatile memory | Requires continuous MCU supervision to retain setting; unsuitable for unattended power-cycle recovery | Select if I²C bus availability and higher resistance range outweigh need for auto-recall |
| MCP41010-I/P | 10 kΩ; SPI interface; volatile wiper register only; no EEPROM storage | Needs host MCU to reload wiper value at boot; lacks autonomous power-on default behavior | Prefer when SPI integration already exists and system-level initialization handles calibration persistence |
Compared with AD5201BRMZ-10 and MCP41010-I/P, the X9C102P uniquely provides guaranteed power-on wiper recall without host intervention, 1 kΩ low-resistance option for current-sensing paths, and minimal three-wire control - making it optimal for self-contained analog calibration in resource-constrained embedded systems.

FAQ
What is the end-to-end resistance tolerance of the X9C102P?
The X9C102P has an end-to-end resistance of 1 kΩ with a tolerance of ±20%, as specified in the FN8222 datasheet Absolute Maximum Ratings and Electrical Specifications tables. This variation must be accounted for in precision voltage-divider designs, though ratiometric performance remains stable due to matched temperature coefficients across the resistor array.
Does the X9C102P retain its wiper position after power loss?
Yes, the X9C102P stores the wiper position in nonvolatile memory and automatically recalls it upon power-up. The recall occurs once VCC reaches its final value, and the stored value persists for up to 100 years under normal operating conditions - no external EEPROM or MCU backup is required for this function in the X9C102P.
Can the X9C102P operate with bipolar analog voltages?
Yes, the X9C102P supports terminal voltages from −5 V to +5 V relative to VSS, enabled by its internal charge pump. This allows direct use in bipolar op-amp circuits, AC-coupled signal paths, or dual-supply systems without external level-shifting components - a key capability confirmed in the FN8222 datasheet Pin Descriptions and Absolute Maximum Ratings sections.
What package type is used for the X9C102P part number?
The X9C102P corresponds to the 8-lead PDIP (Plastic Dual-In-Line Package) with MDP0031 outline, as documented in the Ordering Information table of FN8222 Rev 4.00. This through-hole package is RoHS-compliant and intended for wave solder processing, not reflow.
How many wiper positions does the X9C102P support, and what is the resolution step size?
The X9C102P supports 100 discrete wiper positions across its 1 kΩ resistor array, corresponding to 99 resistive elements. Each step represents a minimum increment (MI) of approximately 10.1 Ω (1 kΩ ÷ 99), yielding ~1% resolution - confirmed in the Electrical Specifications table under "Resolution" and "Absolute Linearity" notes.
