Product details
Overview
X9317WPI-2.7 from Renesas Electronics is a digitally controlled potentiometer (XDCP™) with 100 wiper tap points, nonvolatile wiper position storage, and 3-wire serial up/down interface. It features 10 kΩ end-to-end resistance, operates from 2.7 V to 5.5 V, and delivers ±1% absolute linearity for precision voltage divider or variable resistor applications in analog signal conditioning circuits.
For engineers reviewing the X9317WPI-2.7 datasheet, X9317WPI-2.7 pinout, X9317WPI-2.7 application, or X9317WPI-2.7 equivalent, this device supports low-noise DC bias adjustment, laser diode current control, and gain/offset trim where power-up repeatability and solid-state reliability are critical.
Technical Context
The X9317WPI-2.7 implements a 99-element resistor array with make-before-break wiper switching, enabling glitch-free tap transitions. Its 7-bit counter drives a decoder that selects one of 100 discrete wiper positions, with wiper resistance specified at 400 Ω (max) at 2.7 V supply.
Control logic responds to negative-edge-triggered INC pulses while CS is low, with U/D determining direction. Nonvolatile store occurs on CS rising edge when INC is high, retaining position for ≥100 years with 100,000 write cycles per bit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - defines full-scale analog range for voltage division or current limiting |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct compatibility with 3.3 V and 5 V systems without level shifting |
| Wiper Resolution | 100 taps (1% step size) - provides 99 discrete resistance ratios between RH and RL terminals |
| Absolute Linearity | ±1 MI (Minimum Increment) - ensures ≤1% deviation from ideal voltage divider output across all taps |
| Standby Current | <5 µA - minimizes quiescent power in battery-powered or always-on analog front-ends |
| Wiper Resistance | 400 Ω max at 2.7 V - limits insertion error in low-impedance feedback paths |
| Nonvolatile Retention | 100 years - guarantees factory-trimmed or user-calibrated settings persist over product lifetime |
Pinout & Package
Package: 8-lead MSOP (M8.118), RoHS-compliant, 3.0 mm × 3.0 mm footprint, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control signal; toggling moves wiper up/down based on U/D state |
| 2 (U/D) | Direction control | Logic level sets wiper movement direction during each INC pulse; stable during CS active |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher potential in voltage divider configurations |
| 4 (VSS) | Ground reference | Return path for internal logic and analog array; must be low-impedance for noise immunity |
| 5 (RW) | Wiper terminal | Movable contact point; output node for voltage division or adjustable current path |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential or ground in standard configurations |
| 7 (CS) | Chip select | Active-low enable; initiates control mode when low, triggers nonvolatile store on rising edge with INC high |
| 8 (VCC) | Power supply | 2.7–5.5 V digital/analog rail; powers internal CMOS logic and resistor array bias circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, contact bounce, and environmental sensitivity of trim pots |
| 3-wire serial interface | Requires only CS, U/D, and INC signals-no clock or data lines-simplifying MCU GPIO usage |

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 taps, 10 kΩ, 2.7–5.5 V, but no nonvolatile memory | Requires host MCU to reinitialize wiper position at every power-up | Preferred when I²C bus availability and higher resolution outweigh need for autonomous power-up behavior |
| MCP41010-I/P | SPI interface, 256 taps, 10 kΩ, 2.7–5.5 V, volatile wiper register only | No persistent setting retention; external EEPROM or MCU firmware needed for recall | Chosen for SPI-native systems where board space allows added memory or initialization code overhead |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9317WPI-2.7 uniquely eliminates boot-time calibration dependency by restoring wiper position autonomously-critical for unattended or safety-critical analog subsystems where deterministic startup behavior is mandatory.

FAQ
What is the operating temperature range for the X9317WPI-2.7?
The X9317WPI-2.7 is rated for commercial operation from 0°C to +70°C. Its specifications-including end-to-end resistance tolerance, linearity, and standby current-are guaranteed across this range. The device uses temperature-compensated resistor elements to maintain ratiometric stability, with a typical ratiometric temperature coefficient of ±20 ppm/°C.
Does the X9317WPI-2.7 require external components to function?
No, the X9317WPI-2.7 operates autonomously with only VCC, VSS, and three digital control signals (CS, U/D, INC). It contains an integrated 99-element resistor array, wiper switching network, 7-bit up/down counter, and nonvolatile memory-no external capacitors, resistors, or clock sources are needed for basic operation or power-up recall.
How is nonvolatile storage triggered on the X9317WPI-2.7?
Nonvolatile storage on the X9317WPI-2.7 occurs automatically when the CS pin transitions from low to high while the INC pin is held high. This store cycle takes 5–10 ms and places the device into standby mode upon completion. The stored wiper position is recalled within 5 µs after VCC stabilizes during subsequent power-up.
Can the X9317WPI-2.7 be used in a two-terminal variable resistor configuration?
Yes, the X9317WPI-2.7 supports two-terminal operation by connecting either RH or RL to the same node as RW, effectively using the wiper and one fixed terminal as a programmable resistor. In this mode, the maximum usable resistance is 10 kΩ, and wiper resistance (≤400 Ω at 2.7 V) contributes directly to total series impedance.
What is the maximum wiper current rating for the X9317WPI-2.7 at 2.7 V supply?
At VCC = 2.7 V, the X9317WPI-2.7 specifies a maximum wiper current (IW) of ±4.4 mA. This limit applies regardless of tap position and ensures safe operation within the device's 10 mW total power rating for RTOTAL ≥ 10 kΩ. Exceeding this current risks accelerated wear or parametric shift.
