Product details
Overview
X9317WV8Z-2.7T1 from Renesas Electronics is a low-noise, low-power, 100-tap digitally controlled potentiometer (XDCP™) with nonvolatile wiper position storage, 2.7V–5.5V supply range, 10kΩ end-to-end resistance, and TSSOP-8 package. It functions as a solid-state three-terminal voltage divider or two-terminal variable resistor for precision analog trimming in embedded systems.
For engineers reviewing the X9317WV8Z-2.7T1 datasheet, X9317WV8Z-2.7T1 pinout, X9317WV8Z-2.7T1 application, or X9317WV8Z-2.7T1 equivalent, key selection criteria include its 100-tap resolution, ±20% RTOTAL tolerance, <5µA standby current, temperature-compensated resistor array, and 3-wire up/down interface compatibility with microcontroller GPIOs.
Technical Context
The X9317WV8Z-2.7T1 implements a 99-element resistor ladder 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 (0–99), with absolute linearity ±1 MI and relative linearity ±0.2 MI.
Control logic responds to CS (chip select), U/D (direction), and edge-triggered INC inputs; wiper position is stored to nonvolatile memory when CS rises while INC is high. The device operates across 0°C to +70°C and supports ratiometric operation with ±20 ppm/°C ratiometric temperature coefficient.
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 configurations |
| Supply Voltage Range | 2.7V to 5.5V - enables direct interfacing with 3.3V and 5V logic without level shifters |
| Standby Current | <5µA - minimizes quiescent power in battery-powered or always-on trim applications |
| Wiper Resistance | 200Ω typical at 5V, 400Ω typical at 2.7V - impacts signal integrity and loading in high-impedance feedback paths |
| Resolution | 1% (100 taps) - provides 9.9mV step resolution across 1V span, suitable for fine gain/offset calibration |
| Nonvolatile Storage Endurance | 100,000 write cycles - supports field recalibration and lifetime parameter tuning without wear-out concerns |
| Power-up Wiper Recall | Automatic - restores last-stored position within 5µs after VCC stabilization, ensuring deterministic startup behavior |
Pinout & Package
Package: 8-lead TSSOP (JEDEC MO-153, variation AC), 4.4mm × 3.0mm body, 0.65mm pitch, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control line; toggling moves wiper up/down per U/D state; requires tCYC ≥ 2µs |
| 2 (U/D) | Direction control input | Logic level sets wiper movement direction during INC transitions; stable during CS active |
| 3 (RH) | High terminal | Fixed end of resistor array; connected to higher potential in voltage divider mode |
| 4 (VSS) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity |
| 5 (RW) | Wiper output | Movable terminal; delivers interpolated voltage/current; series resistance ≤400Ω at 2.7V affects loop gain accuracy |
| 6 (RL) | Low terminal | Fixed end of resistor array; connected to lower potential (e.g., ground or bias node) |
| 7 (CS) | Chip select | Active-low enable; rising edge with INC high initiates nonvolatile store; deactivates device into standby |
| 8 (VCC) | Supply voltage | 2.7V–5.5V power rail; powers internal logic, memory, and resistor array; decoupling required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Retains last-set tap position across power cycles for deterministic system boot behavior |
| Temperature-compensated resistor array | ±300 ppm/°C total resistance drift enables stable trimming over industrial temperature ranges |

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, 10kΩ, same 8-lead MSOP package but different pinout | Requires I²C host controller instead of GPIO-driven up/down; higher resolution but no nonvolatile store on power-up | Select for systems with I²C infrastructure and need for finer adjustment granularity |
| MCP41010-I/P | Serial SPI interface, 256-tap, 10kΩ, 8-lead PDIP package, volatile wiper position | No automatic power-up recall; requires external MCU initialization; larger through-hole footprint | Select for cost-sensitive prototyping where manual calibration is acceptable |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9317WV8Z-2.7T1 offers deterministic power-up behavior via nonvolatile recall, GPIO-compatible 3-wire control, and TSSOP-8 packaging optimized for space-constrained PCBs-making it ideal for production-grade analog trimming where reliability and layout efficiency are critical.

FAQ
What is the maximum operating temperature range for the X9317WV8Z-2.7T1?
The X9317WV8Z-2.7T1 is rated for commercial temperature operation from 0°C to +70°C, as confirmed by the ordering information table in the FN8183 Rev.10.01 datasheet. Its TSSOP-8 package (drawing M8.173) and internal circuitry are characterized and specified across this range, with parameters like absolute linearity (±1 MI) and ratiometric temperature coefficient (±20 ppm/°C) guaranteed within these limits.
Does the X9317WV8Z-2.7T1 require an external clock or microcontroller to operate?
No, the X9317WV8Z-2.7T1 operates with simple GPIO-level signals: CS (active-low chip select), U/D (direction control), and INC (negative-edge-triggered increment). It contains an internal 7-bit up/down counter and decoder, eliminating need for external clocks or firmware. The X9317WV8Z-2.7T1 only requires a host system to toggle INC while holding CS low and U/D at the desired logic level.
How does the nonvolatile memory in the X9317WV8Z-2.7T1 retain wiper position during power loss?
The X9317WV8Z-2.7T1 stores wiper position in on-chip nonvolatile memory using standard CMOS floating-gate technology. When CS rises while INC is high, the current counter value is written to memory. After power removal, the stored value persists for 100 years (per datasheet specification) and is automatically loaded to the wiper register within 5µs of VCC stabilization during subsequent power-up.
Can the X9317WV8Z-2.7T1 be used in a two-terminal variable resistor configuration?
Yes, the X9317WV8Z-2.7T1 supports two-terminal operation by connecting either RH or RL to RW and using the remaining terminal with RW as the variable resistance element. Datasheet Figure 4 explicitly shows this configuration for current control. In this mode, the effective resistance varies from near 0Ω (wiper at terminal) to RTOTAL (wiper at opposite end), with wiper resistance (≤400Ω at 2.7V) contributing to minimum on-resistance.
What is the wiper resistance specification for the X9317WV8Z-2.7T1 at 2.7V supply?
Per the Potentiometer Specifications table on page 4 of FN8183 Rev.10.01, the X9317WV8Z-2.7T1 has a wiper resistance of 400Ω typical and 1000Ω maximum at VCC = 2.7V. This value directly impacts insertion loss and gain error in precision feedback networks, especially in low-voltage applications where series resistance constitutes a larger percentage of total resistance.
