Product details
Overview
X9317WP from Renesas Electronics is a digitally controlled potentiometer (XDCP™) implementing a 99-element resistor array with 100 wiper tap positions, nonvolatile wiper position storage, and 3-wire up/down serial interface. It functions as a three-terminal voltage divider or two-terminal variable resistor for precision analog trimming in DC bias, gain/offset, and laser diode control circuits.
For engineers reviewing the X9317WP datasheet, X9317WP pinout, X9317WP application, or X9317WP equivalent, this page delivers verified specifications, package mapping to 8-lead SOIC/TSSOP/MSOP, real-world use cases, and validated alternative parts - all grounded in Renesas FN8183 Rev.10.01.
Technical Context
The X9317WP uses a 7-bit up/down counter decoded to select one of 100 wiper positions across a temperature-compensated resistor array. Its "make-before-break" wiper switching ensures continuity during transitions, while nonvolatile memory retains the last stored position across power cycles.
Control relies on three dedicated digital inputs: CS (chip select), U/D (direction), and INC (edge-triggered increment/decrement). A store operation occurs only when CS rises while INC is high, enabling deterministic configuration persistence without unintended writes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 10 kΩ ±20% - defines full-scale analog range and load interaction in voltage divider configurations |
| Wiper resolution | 100 taps (1% step size) - enables fine-grained adjustment of bias points or feedback ratios |
| Supply voltage range | 2.7 V to 5.5 V - supports single-supply operation across industrial and commercial rails including 3.3 V and 5 V systems |
| Standby current | <5 µA - minimizes quiescent power in battery-backed or energy-sensitive applications |
| Wiper resistance | 200 Ω typical at 5 V - contributes predictable series impedance in current-sensing or amplifier feedback paths |
| Nonvolatile endurance | 100,000 write cycles - ensures long-term reliability for field-adjustable calibration routines |
| Temperature coefficient | ±300 ppm/°C (absolute), ±20 ppm/°C (ratiometric) - maintains stable resistance ratio over temperature for precision trimming |
| Low-noise performance | −120 dBV @ 1 kHz - preserves signal integrity in audio, sensor, and reference voltage circuits |
Pinout & Package
Package: 8-lead SOIC (M8.15E), TSSOP (M8.173), or MSOP (M8.118); RoHS-compliant, Pb-free, rated for −40°C to +85°C (industrial) or 0°C to +70°C (commercial).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SOIC/MSOP), 3 (TSSOP) | INC | Negative-edge-triggered input controlling wiper movement; toggling moves wiper one tap per edge |
| 2 (SOIC/MSOP), 4 (TSSOP) | U/D | Direction control: logic high increments wiper toward RH, low decrements toward RL |
| 3 (SOIC/MSOP), 5 (TSSOP) | RH | High terminal - fixed end of resistor array; connects to VCC or reference voltage in divider mode |
| 4 (SOIC/MSOP), 6 (TSSOP) | VSS | Ground reference for supply and logic interface; must be tied to system common |
| 5 (SOIC/MSOP), 7 (TSSOP) | RW | Wiper output - movable terminal delivering intermediate voltage or variable resistance; 200 Ω typical series resistance |
| 6 (SOIC/MSOP), 8 (TSSOP) | RL | Low terminal - fixed end of resistor array; connects to ground or signal return in divider mode |
| 7 (SOIC/MSOP), 1 (TSSOP) | CS | Chip select: active-low enables interface; rising edge with INC = high triggers nonvolatile store |
| 8 (SOIC/MSOP), 2 (TSSOP) | VCC | Positive supply rail: powers internal logic, memory, and resistor array; operates from 2.7 V to 5.5 V |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Retains last programmed tap setting across power cycles - eliminates need for host MCU reinitialization at startup |
| 3-wire serial up/down interface | Requires only CS, U/D, and INC signals - simplifies integration with microcontrollers lacking SPI/I²C peripherals |
| Temperature-compensated resistor array | ±20 ppm/°C ratiometric TC ensures stable voltage division ratio over temperature - critical for precision biasing |
| Make-before-break wiper switching | Prevents open-circuit transients during tap changes - avoids glitches in amplifier feedback or regulator control loops |
| Low-power CMOS design | 5 µA standby current enables use in always-on or battery-powered systems without compromising trim stability |
| High-reliability nonvolatile memory | 100-year data retention and 100,000 write cycles support field calibration and lifetime maintenance requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5170BRMZ-10 | I²C interface, 256-tap resolution, 10 kΩ nominal, 3 V to 5.5 V supply | Requires I²C master; higher resolution but no native nonvolatile store on power-up | Choose for systems with I²C infrastructure and need for finer adjustment granularity |
| MCP41010-I/P | SPI interface, 256-tap resolution, 10 kΩ nominal, 2.7 V to 5.5 V supply, volatile wiper register | No nonvolatile memory - wiper resets to mid-scale on power-up unless host reloads value | Choose when SPI is preferred and host MCU can manage initialization sequence reliably |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9317WP offers deterministic power-up behavior via automatic nonvolatile recall, simpler 3-wire control without protocol overhead, and superior ratiometric temperature stability - making it optimal for unattended or safety-critical trimming where default state integrity is essential.

FAQ
What is the supply voltage range supported by the X9317WP?
The X9317WP operates from 2.7 V to 5.5 V, covering both 3.3 V and 5 V system rails. This range is explicitly specified in the Absolute Maximum Ratings and Potentiometer Specifications sections of the FN8183 datasheet. The device supports full functionality-including wiper movement, nonvolatile store, and low-power standby-across this entire range, with ICC1 active current ≤80 µA and ISB standby current <5 µA at VCC = 5 V.
How does the X9317WP retain its wiper position after power loss?
The X9317WP stores the current wiper position in nonvolatile memory upon a specific control sequence: CS must transition from low to high while the INC input is held high. Once stored, the value persists for 100 years and is automatically recalled at power-up, positioning the wiper to the last saved tap. This behavior is confirmed in the "Principles of Operation" and "Power-up and Down Requirements" sections of the FN8183 datasheet.
What package types are available for the X9317WP?
The X9317WP is offered in three RoHS-compliant 8-lead packages: SOIC (M8.15E), TSSOP (M8.173), and MSOP (M8.118). Each is qualified for industrial (−40°C to +85°C) or commercial (0°C to +70°C) temperature ranges, with thermal resistance values documented in the datasheet (e.g., θJA = 155°C/W for TSSOP). Pinouts are identical across packages, enabling drop-in substitution based on board space constraints.
Does the X9317WP support true 3-wire serial communication without clock or data lines?
Yes - the X9317WP uses a dedicated 3-wire up/down interface consisting solely of CS (chip select), U/D (up/down direction), and INC (increment toggle). No clock or bidirectional data line is required. Each negative edge on INC moves the wiper one tap in the direction set by U/D, and CS controls selection and nonvolatile store initiation. This architecture is detailed in Figure 1 (Block Diagram) and the "Pin Descriptions" section of FN8183.
What is the maximum wiper current rating for the X9317WP?
The X9317WP specifies a maximum wiper current (IW) of ±4.4 mA under normal operating conditions, as defined in the Absolute Maximum Ratings table. This limit applies regardless of VCC level and ensures safe operation when used as a two-terminal variable resistor in current-control applications such as laser diode biasing or LED current setting. Exceeding this value risks degradation of wiper switch reliability over time.
