Product details
Overview
X9317TS8IZ-2.7 from Renesas Electronics is a digitally controlled potentiometer (XDCP™) with 100 wiper tap points, nonvolatile wiper position storage, and 2.7V to 5.5V supply operation. It implements a 99-element resistor array with temperature-compensated end-to-end resistance tolerance of ±20%, wiper resistance ≤400Ω at 2.7V, and standby current <5µA. It serves as a three-terminal voltage divider or two-terminal variable resistor in precision analog trim applications.
For engineers reviewing the X9317TS8IZ-2.7 datasheet, X9317TS8IZ-2.7 pinout, X9317TS8IZ-2.7 application, or X9317TS8IZ-2.7 equivalent, this page delivers verified specifications, package mapping, functional context, and real-world use cases - all confirmed for the exact X9317TS8IZ-2.7 variant with MSOP-8 packaging, -40°C to +85°C temperature range, and 10kΩ end-to-end resistance.
Technical Context
The X9317TS8IZ-2.7 integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 99 resistive elements. Its 3-wire serial interface (CS, U/D, INC) enables deterministic, edge-triggered wiper movement without clock or data lines beyond those three signals.
Wiper position is stored on CS↑ with INC HIGH and recalled automatically at power-up. The device operates in "make-before-break" switching mode, ensuring continuity during tap transitions, and supports both voltage-divider (RH–RW–RL) and variable-resistor (RW–RL or RW–RH) configurations with ratiometric temperature coefficient of ±20 ppm/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - defines full-scale analog adjustment range and load interaction in voltage divider or current-limiting roles. |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct compatibility with 3.3 V and 5 V systems, including battery-powered or low-voltage industrial designs. |
| Wiper Resistance | ≤400 Ω at VCC = 2.7 V - limits voltage error and signal attenuation when wiper is used as active output node. |
| Standby Current | <5 µA - ensures negligible quiescent power draw during system sleep or idle states. |
| Tap Resolution | 100 positions (0–99) - provides 1% step resolution for fine-grained analog calibration without external DACs. |
| Nonvolatile Storage | 100-year data retention, 100,000 write cycles - guarantees factory-set or field-trimmed values survive power cycling and long-term deployment. |
| Temperature Coefficient | ±300 ppm/°C (absolute), ±20 ppm/°C (ratiometric) - maintains stable resistance ratio across temperature, critical for bias and gain stability. |
| Interface Type | 3-wire asynchronous up/down - eliminates need for clock generation, SPI framing, or address decoding in microcontroller-constrained systems. |
Pinout & Package
Package: 8-lead MSOP (Moisture Sensitivity Level 1, RoHS-compliant, JEDEC MO-187-AA compliant, dimensions per M8.118 Rev 5).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment control input | Negative-edge-triggered signal that advances or retracts wiper position based on U/D state; requires no external pull-up. |
| 2 (U/D) | Direction control input | Logic level (HIGH = increment, LOW = decrement) sets wiper movement direction during each INC transition. |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher-potential rail in voltage divider or one side of variable resistor. |
| 4 (VSS) | Ground reference | System ground return for internal logic and resistor array; must be low-impedance for noise-sensitive analog paths. |
| 5 (RW) | Wiper terminal | Movable contact point; output node for voltage division or adjustable resistance; series resistance ≤400 Ω at 2.7 V. |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower-potential rail (e.g., ground or negative bias) in voltage divider or other terminal in variable resistor. |
| 7 (CS) | Chip select | Active-low enable; initiates wiper movement when LOW; triggers nonvolatile store on rising edge while INC = HIGH. |
| 8 (VCC) | Supply voltage | 2.7 V to 5.5 V power rail; powers internal CMOS logic and switch drivers; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, contact bounce, and environmental drift - enabling >100,000 adjustments over product lifetime. |
| Nonvolatile wiper position storage | Recalls last-trimmed setting at every power-on, removing need for host MCU initialization or calibration routines. |
| Temperature-compensated resistor array | ±20 ppm/°C ratiometric TC ensures stable voltage division ratio across -40°C to +85°C, critical for sensor bias and regulator feedback. |
| Low-power 3-wire interface | Requires only three GPIOs and zero clock resources - ideal for resource-limited MCUs or FPGA I/O-constrained designs. |
| Make-before-break wiper switching | Prevents open-circuit transients during tap changes, avoiding glitches in amplifier feedback or bias networks. |
| Pb-free MSOP-8 packaging | Compact 3.0 mm × 3.0 mm footprint with 0.65 mm pitch supports high-density PCB layouts and automated assembly. |
Applications
| LCD Bias Control | Laser Diode Bias Control |
|---|---|
Use Scenario: Adjusting VCOM or gamma reference voltages in TFT-LCD driver circuits to compensate for panel variation and aging. IC Role / Device Role / Timing Role: Three-terminal voltage divider providing precise, stable DC bias voltage referenced to display ground and supply rails. Use Value: Enables factory and field calibration without potentiometer replacement; ±20 ppm/°C ratiometric TC maintains grayscale uniformity across operating temperature. |
Use Scenario: Setting precise forward current for laser diodes in optical transceivers or sensing modules where thermal drift affects output power. IC Role / Device Role / Timing Role: Two-terminal variable resistor in the cathode path of constant-current laser driver ICs to adjust compliance voltage and current limit. Use Value: Nonvolatile storage retains calibrated current value after power cycle; ≤400 Ω wiper resistance minimizes voltage drop and thermal error at 2.7 V operation. |
| Voltage Regulator Output Control | Gain and Offset Trim |
Use Scenario: Fine-tuning feedback divider ratio in adjustable LDOs or DC-DC converters to meet tight output voltage tolerances (<±1%) across production lots. IC Role / Device Role / Timing Role: Replaces fixed resistor in upper leg of feedback network; RH and RL connect to VOUT and FB, RW connects to FB node. Use Value: 100-step resolution allows sub-millivolt adjustments; ±20% RTOTAL tolerance accommodates standard 1% feedback resistors without recalibration. |
Use Scenario: Calibrating offset null and gain scaling in instrumentation amplifiers or ADC front-ends during production test or field maintenance. IC Role / Device Role / Timing Role: Two-terminal variable resistor in op-amp offset null circuit or gain-setting network (e.g., Rf/Rin ratio). Use Value: Low 5 µA standby current avoids loading reference sources; make-before-break switching prevents transient injection into sensitive analog nodes. |
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 storage - wiper resets to midscale on power-up. | Requires host MCU to reprogram wiper position at boot; unsuitable for unattended or battery-backed systems needing persistent settings. | Select AD5170BRMZ-10 only if I²C bus availability and software-controlled initialization are acceptable trade-offs for higher resolution. |
| MCP41HV51-103 | 100 kΩ end-to-end resistance, SPI interface, 2.7–5.5 V, volatile wiper with optional EEPROM store (separate command, not automatic on CS↑). | Higher RTOTAL increases sensitivity to parasitic capacitance and noise; SPI adds pin count and firmware overhead vs. 3-wire up/down. | Choose MCP41HV51-103 only when 100 kΩ impedance matching is required or when existing SPI infrastructure justifies added complexity. |
Compared with AD5170BRMZ-10 and MCP41HV51-103, the X9317TS8IZ-2.7 uniquely combines automatic nonvolatile recall, minimal 3-wire control, and guaranteed 10 kΩ resistance - making it optimal for self-initializing analog trim where reliability, simplicity, and deterministic power-up behavior are mandatory.

FAQ
What is the operating temperature range for the X9317TS8IZ-2.7?
The X9317TS8IZ-2.7 is rated for -40°C to +85°C operation, validated across its full electrical specification range. This industrial-grade temperature capability is confirmed in the Ordering Information table (Page 2) and Absolute Maximum Ratings section (Page 4) of the FN8183 Rev.10.01 datasheet. The device maintains specified wiper resistance, linearity, and nonvolatile retention within this range.
Does the X9317TS8IZ-2.7 require an external clock or microcontroller firmware to store wiper position?
No. The X9317TS8IZ-2.7 stores wiper position automatically upon detection of a rising edge on the CS pin while the INC pin is held HIGH - no external clock, SPI/I²C transaction, or firmware routine is needed. This hardware-triggered nonvolatile store is intrinsic to the device's control architecture and is documented in the "Principles of Operation" and "Mode Selection" sections (Pages 8–9) of the datasheet.
What is the maximum wiper current rating for the X9317TS8IZ-2.7 at 2.7 V supply?
At VCC = 2.7 V, the X9317TS8IZ-2.7 supports a maximum wiper current (IW) of ±4.4 mA, as specified in the Potentiometer Specifications table (Page 4). This rating applies across the full operating temperature range and is measured with RH and RL biased between VSS and VCC. Exceeding this current may degrade wiper resistance stability or endurance.
Can the X9317TS8IZ-2.7 be used in a two-terminal variable resistor configuration?
Yes. The X9317TS8IZ-2.7 supports two-terminal operation by connecting either RH or RL to the same node as RW (e.g., RW–RL shorted), using the remaining terminal as the second connection point. This configuration is explicitly illustrated in Figure 4 ("Two Terminal Variable Resistor") and described in the Applications Information section (Page 9) of the datasheet.
Is the X9317TS8IZ-2.7 pin-compatible with other X9317 variants in MSOP-8 packaging?
Yes. All X9317 variants in 8-lead MSOP packaging - including X9317WM8IZ-2.7, X9317WM8Z-2.7, and X9317TS8IZ-2.7 - share identical pinout, footprint, and solder pad layout per M8.118 package drawing. Differences are limited to temperature grade (-40°C to +85°C for 'I' suffix), supply range ('-2.7' denotes 2.7–5.5 V), and end-to-end resistance (10 kΩ for 'T'/'W' suffixes).
