Product details
Overview
X9317UM8IZ 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 operates from 2.7V to 5.5V, delivers ±20% end-to-end resistance tolerance, and supports voltage divider or variable resistor configurations in precision analog trimming applications.
For engineers reviewing the X9317UM8IZ datasheet, X9317UM8IZ pinout, X9317UM8IZ application, or X9317UM8IZ equivalent, key selection criteria include industrial temperature range (-40°C to +85°C), MSOP-8 package, 10kΩ total resistance, low standby current (<5µA), and nonvolatile recall on power-up.
Technical Context
The X9317UM8IZ integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 100 discrete taps. Its solid-state architecture uses make-before-break switching, eliminating mechanical wear and enabling 100,000 data changes per bit with 100-year data retention.
It features temperature-compensated resistive elements with ±300 ppm/°C total resistance TC and ±20 ppm/°C ratiometric TC, ensuring stable voltage division under thermal drift. The 3-wire interface (CS, U/D, INC) supports edge-triggered wiper movement without clock or address overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10kΩ ±20% - defines full-scale analog adjustment range and load interaction in voltage divider or current-limiting roles |
| Wiper Tap Count | 100 positions - enables 1% resolution for fine-grained bias, gain, or offset calibration |
| Supply Voltage Range | 2.7V to 5.5V - supports single-supply operation across legacy 3.3V and modern mixed-voltage systems |
| Standby Current | <5µA - minimizes quiescent power in battery-powered or always-on trim circuits |
| Nonvolatile Recall | Automatic on power-up - eliminates boot-time reinitialization and ensures repeatable startup conditions |
| Operating Temperature | -40°C to +85°C - qualified for industrial environments including motor drives and outdoor instrumentation |
| Wiper Resistance | 200Ω typical at 5V - limits signal path error in high-impedance feedback networks |
Pinout & Package
Package: 8-lead MSOP (M8.118), RoHS-compliant, moisture sensitivity level (MSL) 1, body dimensions 3.0mm × 3.0mm × 0.85mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment input | Negative-edge-triggered control line; toggling moves wiper one tap in direction set by U/D |
| 2 (U/D) | Up/down direction control | Logic level determines wiper increment (+) or decrement (–) on each INC edge |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher potential in voltage divider configuration |
| 4 (VSS) | Ground reference | Return path for supply and signal; must be low-impedance for noise-sensitive analog use |
| 5 (RW) | Wiper terminal | Movable contact point; output node for adjustable voltage or resistance; series R ≈200Ω |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential (e.g., ground or negative rail) |
| 7 (CS) | Chip select | Active-low enable; HIGH initiates nonvolatile store when INC is also HIGH |
| 8 (VCC) | Supply voltage | Power input for logic and resistor array; supports 2.7V–5.5V with <5µA standby draw |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last-set position across power cycles without external EEPROM or MCU intervention |
| Make-before-break switching | Prevents open-circuit transients during wiper movement, critical for stable amplifier bias networks |
| Ratiometric temperature coefficient | ±20 ppm/°C - maintains voltage division ratio accuracy despite ambient thermal shifts |
| Low-noise performance | -120 dBV (ref 1 kHz) - suitable for audio and precision sensor signal conditioning paths |
| Industrial-grade reliability | 100,000 write cycles and 100-year data retention - meets long-lifecycle embedded system 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 |
|---|---|---|---|
| AD5171BRMZ-10 | I²C interface, 64 taps, 10kΩ, ±30% RTOTAL tolerance, 500ppm/°C TC | Lacks nonvolatile recall; requires host MCU to reload wiper position at startup | Choose when I²C bus availability and lower cost outweigh need for autonomous power-up behavior |
| MCP41HV51-103 | 10-bit SPI interface, 10kΩ, ±20% RTOTAL, 5.5V max VCC, no nonvolatile memory | Requires continuous SPI communication; no auto-recall; higher wiper resistance (~400Ω) | Select for high-resolution (1024-step) trimming where SPI infrastructure exists and nonvolatility is managed externally |
Compared with AD5171BRMZ-10 and MCP41HV51-103, the X9317UM8IZ uniquely combines 100-tap resolution, guaranteed nonvolatile recall, and ultra-low standby current in an industrial-temperature MSOP package-making it optimal for self-contained, maintenance-free analog calibration.

FAQ
What is the operating temperature range for the X9317UM8IZ?
The X9317UM8IZ is rated for -40°C to +85°C, qualifying it for industrial environments such as motor control modules, outdoor instrumentation, and factory automation equipment. This range is confirmed in the Ordering Information table (Page 2) and applies to all electrical specifications unless otherwise noted. The device maintains specified linearity, resistance tolerance, and nonvolatile recall performance across this full span.
Does the X9317UM8IZ retain its wiper position after power loss?
Yes, the X9317UM8IZ stores the wiper position in nonvolatile memory and automatically recalls it on power-up. This behavior is inherent to the device architecture and requires no external components or host initialization. The datasheet specifies 100-year data retention and 100,000 write cycles, making X9317UM8IZ suitable for applications where consistent startup conditions are mandatory, such as medical calibration or telecom bias settings.
What package type does the X9317UM8IZ use?
The X9317UM8IZ uses an 8-lead MSOP package (drawing M8.118), measuring 3.0mm × 3.0mm × 0.85mm with gull-wing leads. This compact RoHS-compliant outline is explicitly listed in the Ordering Information table (Page 2) and detailed in Package Outline Drawing M8.118 (Page 11). It is distinct from SOIC and TSSOP variants and supports surface-mount assembly with standard reflow profiles.
How many wiper positions does the X9317UM8IZ support?
The X9317UM8IZ provides exactly 100 discrete wiper tap positions, corresponding to a 99-resistor-element array with endpoints. This is stated in the device title ("100 Taps"), block diagram (Figure 1), and Pin Descriptions section. Each tap represents 1% resolution of the full-scale resistance, enabling precise analog adjustments without interpolation or external DAC support.
What is the supply voltage range for the X9317UM8IZ?
The X9317UM8IZ operates from 2.7V to 5.5V, as confirmed in the "Potentiometer Specifications" table (Page 4) under VCC for X9317-2.7 variants. This extended range accommodates both 3.3V and 5V systems and remains valid across the full -40°C to +85°C temperature range. Standby current stays below 5µA across this entire voltage window.
