Product details
Overview
X9317WM8IZ-2.7 from Renesas Electronics is a digitally controlled potentiometer (XDCP™) with 100 wiper tap points, nonvolatile wiper position storage, and 10 kΩ end-to-end resistance. It operates from 2.7 V to 5.5 V, consumes <5 µA standby current, and uses a 3-wire up/down interface for voltage divider or variable resistor applications in precision analog trimming.
For engineers reviewing the X9317WM8IZ-2.7 datasheet, X9317WM8IZ-2.7 pinout, X9317WM8IZ-2.7 application, or X9317WM8IZ-2.7 equivalent, this device supports industrial-grade (-40°C to +85°C) bias control, gain/offset trim, and laser diode regulation where power efficiency, temperature-stable linearity, and power-up repeatability are critical.
Technical Context
The X9317WM8IZ-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 absolute linearity ±1 MI and ratiometric temperature coefficient ±20 ppm/°C.
Control logic responds to CS (chip select), U/D (direction), and edge-triggered INC inputs. Wiper position is stored in nonvolatile memory on CS↑ with INC HIGH and recalled automatically at power-up - no external configuration required.
Key Specifications

|---|---|
| End-to-end resistance | 10 kΩ ±20% - defines full-scale voltage division range and load interaction in bias networks |
| 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 fine-grained analog adjustment for calibration-critical circuits |
| Standby current | <5 µA - minimizes quiescent power in battery-backed or always-on instrumentation |
| Nonvolatile endurance | 100,000 data changes per bit - supports field recalibration over product lifetime without wear-out risk |
| Operating temperature | -40°C to +85°C - qualified for industrial environments including automotive cabin and factory automation |
| Wiper resistance | 200 Ω typical (at 5 V), 400 Ω typical (at 2.7 V) - impacts signal integrity in high-impedance feedback paths |
| Noise | -120 dBV (ref 1 kHz) - ensures low-noise performance in sensitive analog front-ends and sensor interfaces |
Pinout & Package
Package: 8-lead MSOP (M8.118), RoHS-compliant, -40°C to +85°C operating range.
| 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 input | Logic level determines wiper movement direction during INC transitions |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher potential in voltage divider configurations |
| 4 (VSS) | Ground reference | System ground return for internal logic and resistor array; must be low-impedance |
| 5 (RW) | Wiper output | Movable terminal; delivers tapped voltage/current; series resistance affects loading in precision buffers |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential or ground in voltage divider use |
| 7 (CS) | Chip select | Active-low enable; HIGH with INC HIGH initiates nonvolatile store; LOW enables real-time wiper control |
| 8 (VCC) | Power supply | 2.7–5.5 V CMOS supply; powers logic, memory, and array; decoupling required near pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5241BRMZ10 | I²C interface, 1024-tap resolution, 10 kΩ, ±30% RTOTAL tolerance, 100-year data retention | Requires I²C host; higher resolution but looser resistance tolerance affects absolute accuracy | Preferred when system already uses I²C and finer granularity outweighs tighter RTOTAL spec |
| MCP41010-I/P | SPITM interface, 257-tap resolution, 10 kΩ, ±20% RTOTAL, 1 µA standby current, no nonvolatile store | Needs external EEPROM or MCU firmware to retain wiper position across power cycles | Chosen when SPI-native design exists and power budget is ultra-constrained (<1 µA) |
Compared with AD5241BRMZ10 and MCP41010-I/P, the X9317WM8IZ-2.7 uniquely combines 3-wire simplicity, guaranteed nonvolatile recall at power-up, and industrial temperature rating - reducing firmware overhead and eliminating external memory dependencies in ruggedized analog systems.

FAQ
What is the power-up behavior of the X9317WM8IZ-2.7?
The X9317WM8IZ-2.7 automatically recalls the last wiper position stored in nonvolatile memory upon power-up, stabilizing within 5 µs. No initialization sequence is required - the device is immediately functional as a calibrated potentiometer. This behavior is guaranteed across its full -40°C to +85°C operating range and eliminates need for MCU-driven restore routines in X9317WM8IZ-2.7-based designs.
Does the X9317WM8IZ-2.7 require external pull-up or pull-down resistors on its control pins?
No, the X9317WM8IZ-2.7 does not require external pull-up or pull-down resistors on CS, U/D, or INC inputs. Its CMOS inputs have specified VIH (≥0.7×VCC) and VIL (≤0.1×VCC) thresholds, and leakage current is limited to ±10 µA. However, for noise immunity in electrically noisy environments, a 100 kΩ pull-down on INC and U/D is recommended - but not mandatory for basic X9317WM8IZ-2.7 operation.
Can the X9317WM8IZ-2.7 be used in a two-terminal variable resistor configuration?
Yes, the X9317WM8IZ-2.7 supports two-terminal operation by connecting RH to VCC (or fixed bias) and RL to ground (or return path), using RW as the adjustable terminal. In this mode, it functions as a digitally controlled rheostat with 100-step resolution and 10 kΩ maximum resistance. The X9317WM8IZ-2.7 datasheet confirms this configuration for laser diode bias and current-limiting applications.
What is the maximum wiper current rating for the X9317WM8IZ-2.7 at 2.7 V supply?
At VCC = 2.7 V, the X9317WM8IZ-2.7 supports a maximum wiper current (IW) of ±4.4 mA, with wiper resistance rising to 400–1000 Ω depending on tap position. Exceeding this current risks exceeding the 10 mW total power rating and may cause long-term drift. For continuous operation, design must ensure (VRH – VRL)² / RTOTAL ≤ 10 mW - a key constraint in X9317WM8IZ-2.7 current-sense applications.
How does the X9317WM8IZ-2.7 handle rapid wiper position changes?
The X9317WM8IZ-2.7 uses make-before-break wiper switching, so multiple taps connect briefly during transitions - causing temporary reduction in effective RTOTAL. The INC-to-RW change time is 1–5 µs, and full 100-tap traversal takes ~200 µs. During multi-step moves, transient current spikes must be considered in low-impedance loads; the X9317WM8IZ-2.7 specification explicitly warns against relying on intermediate values during such sequences.
