Product details
Overview
X9317WV8I-2.7T2 from Renesas Electronics is a digitally controlled potentiometer (XDCP™) with 100 wiper tap points, nonvolatile wiper position storage, and 3-wire up/down serial interface. It features 10 kΩ end-to-end resistance, operates from 2.7 V to 5.5 V, and delivers ±1% absolute linearity over –40°C to +85°C - enabling precision DC bias adjustment in industrial power management circuits.
For engineers reviewing the X9317WV8I-2.7T2 datasheet, X9317WV8I-2.7T2 pinout, X9317WV8I-2.7T2 application, or X9317WV8I-2.7T2 equivalent, this device serves as a solid-state replacement for mechanical trimmers in voltage regulator output control, laser diode biasing, LCD bias networks, and gain/offset trimming where power-up repeatability and low standby current (<5 µA) are critical.
Technical Context
The X9317WV8I-2.7T2 implements a 99-element resistor array with make-before-break wiper switching, driven by a 7-bit up/down counter and decoded to select one of 100 discrete tap positions. Its control logic responds to CS (chip select), U/D (direction), and edge-triggered INC (increment) signals - no clock or address bus required.
Wiper position is retained in nonvolatile memory with 100-year data retention and 100,000 write cycles. The device supports both three-terminal potentiometer (voltage divider) and two-terminal variable resistor (current control) configurations, with temperature-compensated ratiometric tracking (±20 ppm/°C) and low 200 Ω typical wiper resistance at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - sets full-scale analog range for voltage division or current limiting 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 adjustment for precision calibration tasks. |
| Absolute Linearity | ±1 MI (Minimum Increment) - ensures ≤1% deviation between ideal and actual wiper voltage across full range. |
| Standby Current | <5 µA - minimizes quiescent power in battery-backed or always-on embedded systems. |
| Nonvolatile Retention | 100 years - guarantees factory-set or user-trimmed values persist through decades of operation. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade reliability in harsh ambient environments. |
Pinout & Package
Package: 8-lead TSSOP (RoHS-compliant, JEDEC MO-153 AC, M8.173 drawing). Compact 4.4 mm × 3.0 mm footprint with 0.65 mm lead pitch, suitable for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control signal; toggling moves wiper up/down per U/D state. |
| 2 (U/D) | Direction control | Logic level selects wiper movement direction during INC transitions - no latching required. |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher potential node in voltage divider configuration. |
| 4 (VSS) | Ground reference | System ground return for internal logic and resistor array; must be low-impedance. |
| 5 (RW) | Wiper output | Movable terminal; presents 200 Ω typical series resistance and tracks selected tap position. |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential node (e.g., ground or negative rail). |
| 7 (CS) | Chip select | Active-low enable; HIGH initiates nonvolatile store when INC is also HIGH. |
| 8 (VCC) | Power supply | 2.7 V–5.5 V CMOS supply; powers logic, memory, and resistor array - no external decoupling mandated but recommended. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, contact bounce, and vibration sensitivity - ideal for field-deployed equipment. |
| 3-wire serial interface | Requires only CS, U/D, and INC signals - no clock, data lines, or address decoding needed. |
| Nonvolatile wiper storage | Automatically recalls last stored position at power-up - ensures repeatable startup behavior without host initialization. |
| Temperature-compensated array | ±300 ppm/°C total resistance drift and ±20 ppm/°C ratiometric tracking - maintains voltage division accuracy across temperature. |
| Low-power CMOS design | 80 µA active current and <5 µA standby draw - extends battery life in portable instrumentation and sensor 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-tap resolution, 10 kΩ, 2.7–5.5 V; higher resolution but no nonvolatile store on power-up. | Requires host MCU I²C support and explicit restore command after power cycle - less autonomous than X9317WV8I-2.7T2. | Choose when higher resolution and I²C integration outweigh need for automatic power-up recall. |
| MCP41HV51-103 | 100 kΩ end-to-end resistance, SPI interface, volatile wiper register, 4.5–20 V supply; higher voltage rating but no NVM. | Needs continuous host refresh to retain position; unsuitable for unattended or battery-powered systems requiring persistent settings. | Choose for high-voltage bias control where 100 kΩ range matches circuit impedance requirements. |
Compared with AD5170BRMZ-10 and MCP41HV51-103, the X9317WV8I-2.7T2 uniquely combines 100-tap resolution, true nonvolatile power-up recall, and minimal 3-wire control - reducing firmware overhead and eliminating external backup power or host intervention for reliable startup behavior.

Does the X9317WV8I-2.7T2 retain its wiper position after power loss?
Yes, the X9317WV8I-2.7T2 stores the wiper position in nonvolatile memory and automatically recalls it upon power-up. This behavior is guaranteed by its 100-year data retention specification and verified endurance of 100,000 write cycles - ensuring calibration stability across decades of operation without host intervention.
How many wiper tap points does the X9317WV8I-2.7T2 provide?
The X9317WV8I-2.7T2 provides exactly 100 wiper tap points, corresponding to 99 resistive elements in its linear array. Each tap represents 1% of full-scale resistance, delivering 1 MI (Minimum Increment) resolution - confirmed in the Block Diagram, Pin Descriptions, and Potentiometer Specifications tables of the FN8183 Rev.10.01 datasheet.
What package type is used for the X9317WV8I-2.7T2?
The X9317WV8I-2.7T2 uses an 8-lead TSSOP package (JEDEC MO-153 AC compliant, drawing M8.173), measuring 4.4 mm × 3.0 mm with 0.65 mm lead pitch. This RoHS-compliant package is explicitly listed in the Ordering Information table under part number X9317WV8IZ-2.7T1, which shares identical electrical and thermal specifications with X9317WV8I-2.7T2.
Can the X9317WV8I-2.7T2 be used as a two-terminal variable resistor?
