Product details
Overview
X9317WM8Z-2.7T1 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 bias control in LCDs and laser diode drivers.
For engineers reviewing the X9317WM8Z-2.7T1 datasheet, X9317WM8Z-2.7T1 pinout, X9317WM8Z-2.7T1 application, or X9317WM8Z-2.7T1 equivalent, this device delivers precise, power-efficient, and memory-retentive analog trimming in space-constrained industrial and commercial systems requiring stable DC bias adjustment without mechanical wear.
Technical Context
The X9317WM8Z-2.7T1 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 wiper positions, with position stored in nonvolatile memory upon CS↑/INC↑ edge.
It supports three-terminal potentiometer (voltage divider) and two-terminal variable resistor (current control) configurations. Temperature-compensated design ensures ±20% RTOTAL tolerance and ±300 ppm/°C total resistance TC over –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - defines full-scale analog range for voltage division or current limiting |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct compatibility with 3.3 V and 5 V logic/system rails |
| Wiper Tap Resolution | 100 positions (0–99) - provides 1% step resolution for fine-grained analog tuning |
| Standby Current | <5 µA - minimizes quiescent power in battery-backed or always-on bias circuits |
| Nonvolatile Storage | 100-year data retention, 100,000 write cycles - eliminates need for external EEPROM or MCU backup |
| Wiper Resistance | 200 Ω typical at 5 V, 400 Ω typical at 2.7 V - impacts minimum load impedance and signal integrity in high-impedance nodes |
| Interface | 3-wire serial (CS, U/D, INC) - requires no clock or data lines; compatible with GPIO-only microcontrollers |
Pinout & Package
Package: 8-lead MSOP (M8.118), RoHS-compliant, 3.0 mm × 3.0 mm footprint, 0.65 mm lead pitch, 0.95 mm height.
| 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 |
| 2 (U/D) | Direction control input | Logic level sets wiper movement direction during INC transitions |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher potential in voltage divider mode |
| 4 (VSS) | Ground reference | Return path for supply and signal currents; must be low-impedance for noise immunity |
| 5 (RW) | Wiper output | Movable terminal; delivers tapped voltage/current; series resistance affects loading |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential or ground in voltage divider mode |
| 7 (CS) | Chip select | Active-low enable; HIGH initiates nonvolatile store when INC is also HIGH |
| 8 (VCC) | Supply voltage | Power rail for internal logic and resistor array; supports 2.7–5.5 V operation |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, contact bounce, and vibration sensitivity in long-life embedded systems |
| Nonvolatile wiper recall | Automatically restores last-trimmed position at power-up-no initialization firmware required |
| Temperature-compensated array | ±20 ppm/°C ratiometric TC ensures stable voltage division across temperature drift |
| Low-noise performance | –120 dBV noise floor (1 kHz ref) enables precision biasing in sensitive analog front-ends |
| Make-before-break switching | Prevents open-circuit glitches during wiper transitions-critical for stable feedback loops |

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 | 256-tap I²C interface; 10 kΩ; 2.7–5.5 V; 500 ppm/°C TC; no nonvolatile store | Requires I²C host; lacks power-up recall; better resolution but higher TC | Choose for I²C systems needing finer steps and no NVM dependency |

FAQ
What is the operating voltage range for the X9317WM8Z-2.7T1?
The X9317WM8Z-2.7T1 operates from 2.7 V to 5.5 V, supporting both 3.3 V and 5 V system rails. This extended low-voltage capability enables use in battery-powered and energy-efficient designs where older DCPs require ≥4.5 V. The device maintains full functionality-including wiper movement, nonvolatile store, and specification compliance-across this entire range.
Does the X9317WM8Z-2.7T1 retain its wiper position after power cycling?
Yes, the X9317WM8Z-2.7T1 stores the wiper position in nonvolatile memory and automatically recalls it on power-up. This behavior is guaranteed by design: when CS transitions HIGH while INC is HIGH, the current counter value is written to memory and retained for 100 years. No external components or MCU intervention are needed for repeatable startup conditions.
How many wiper positions does the X9317WM8Z-2.7T1 support, and what is the resolution?
The X9317WM8Z-2.7T1 supports exactly 100 discrete wiper positions (0 through 99), corresponding to 1% step resolution across the full end-to-end resistance. This is implemented via a 99-resistor ladder and 7-bit counter/decoder. Each step represents a minimum increment (MI) of (VRH − VRL)/99, enabling predictable, monotonic voltage division.
What package type is used for the X9317WM8Z-2.7T1, and is it RoHS-compliant?
The X9317WM8Z-2.7T1 uses an 8-lead MSOP package (drawing M8.118), measuring 3.0 mm × 3.0 mm with 0.65 mm lead pitch. It is fully RoHS-compliant, employing 100% matte tin-plated terminations and Pb-free molding compounds, qualified for both SnPb and lead-free reflow processes per IPC/JEDEC J-STD-020.
Can the X9317WM8Z-2.7T1 be used in two-terminal variable resistor mode?
Yes, the X9317WM8Z-2.7T1 can operate as a two-terminal variable resistor by connecting either RH or RL to RW and using the remaining terminal plus RW as the adjustable element. In this configuration, it functions as a digitally programmable current-limiting or gain-setting resistor-commonly applied in laser diode bias and op-amp gain networks-while retaining all timing, storage, and low-power features.
