Product details
Overview
X9317WS8ZT1 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 functions as a three-terminal voltage divider or two-terminal variable resistor for precision analog trimming in DC-biased circuits.
For engineers reviewing the X9317WS8ZT1 datasheet, X9317WS8ZT1 pinout, X9317WS8ZT1 application, or X9317WS8ZT1 equivalent, key selection criteria include end-to-end resistance tolerance (±20%), wiper resistance (200 Ω typ. at 5 V), standby current (<5 µA), temperature coefficient (±300 ppm/°C), and SOIC-8 RoHS-compliant packaging.
Technical Context
The X9317WS8ZT1 integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 100 discrete taps. Its solid-state architecture eliminates mechanical wear and enables repeatable, temperature-compensated resistance adjustment.
Operation relies on CS-select enable, U/D direction control, and edge-triggered INC input - all compatible with 2.7–5.5 V supply. Wiper movement uses make-before-break switching, and power-up automatically recalls the last stored position from nonvolatile memory.
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 |
| Wiper Resistance | 200 Ω typical at 5 V - impacts minimum achievable output impedance and signal fidelity |
| Supply Voltage Range | 4.5 V to 5.5 V - supports standard 5 V systems without level-shifting |
| Standby Current | <5 µA - enables ultra-low-power operation during system sleep modes |
| Nonvolatile Endurance | 100,000 data changes per bit - ensures long-term reliability in field-adjustable applications |
| Temperature Coefficient | ±300 ppm/°C - maintains resistance stability over industrial temperature range (0°C to +70°C) |
| Resolution | 1% (1/99 step) - provides fine-grained analog tuning capability |
| Interface Type | 3-wire serial (CS/U/D/INC) - simplifies microcontroller GPIO usage without SPI/I²C peripherals |
Pinout & Package
Package: 8-lead narrow-body SOIC (M8.15E), RoHS-compliant, 0°C to +70°C operating range.
| 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 input | Logic level selects 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 | System ground return for internal logic and resistor array |
| 5 (RW) | Wiper output | Movable terminal; delivers tapped voltage or adjustable resistance between RH and RL |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential (e.g., ground) in voltage divider |
| 7 (CS) | Chip select | Active-low enable; HIGH initiates nonvolatile store when INC is also HIGH |
| 8 (VCC) | Supply voltage | 4.5–5.5 V digital/analog supply; powers logic, memory, and resistor array |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Retains last-set tap position across power cycles - eliminates boot-time calibration |
| Temperature-compensated resistor array | ±300 ppm/°C total resistance drift - ensures stable gain/offset trim over ambient variations |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions - avoids signal dropout in sensitive analog paths |
| Low-power CMOS design | <5 µA standby current - suitable for battery-backed or energy-harvesting systems |
| Ratiometric temperature tracking | ±20 ppm/°C - preserves voltage division ratio accuracy under thermal gradients |
| RoHS-compliant SOIC-8 package | Standard footprint compatible with automated assembly and legacy PCB layouts |

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-tap resolution; 10 kΩ nominal; 2.7–5.5 V supply | Requires I²C master; lower resolution limits fine trim granularity | Preferred where I²C bus is already present and 1% resolution suffices |
| MCP41010-I/P | SPI interface; 257-tap resolution; 10 kΩ nominal; 2.7–5.5 V supply | Needs dedicated SPI lines; higher resolution increases firmware complexity | Chosen when maximum resolution and fast update rate are critical |
Compared with AD5171BRMZ-10 and MCP41010-I/P, the X9317WS8ZT1 offers simpler 3-wire control, guaranteed nonvolatile recall at power-up, and optimized low-power standby - making it ideal for cost-sensitive, firmware-light embedded trimming tasks.

FAQ
What is the supply voltage range supported by the X9317WS8ZT1?
The X9317WS8ZT1 operates from 4.5 V to 5.5 V, matching standard 5 V logic and analog rails. It does not support the extended 2.7–5.5 V range found in -2.7 suffix variants. This ensures compatibility with legacy 5 V systems while maintaining noise immunity and stable wiper performance.
How does the X9317WS8ZT1 retain its wiper position after power loss?
The X9317WS8ZT1 stores the current wiper position in nonvolatile memory upon receipt of a store command - triggered by raising CS HIGH while INC is HIGH. On subsequent power-up, the device automatically recalls that value and sets the wiper to the exact same tap position, eliminating need for initialization code.
Can the X9317WS8ZT1 be used as a two-terminal variable resistor?
Yes, the X9317WS8ZT1 can operate as a two-terminal variable resistor by connecting either RH or RL to RW and using the remaining terminal with the wiper. This configuration enables current-mode trimming in LED drivers or sensor bias networks, with full 10 kΩ ±20% resistance range and <5 µA standby draw.
What is the maximum wiper current rating for the X9317WS8ZT1?
The X9317WS8ZT1 specifies a maximum wiper current (IW) of ±4.4 mA. Exceeding this may cause localized heating, accelerated wear, or deviation from linearity specs. For higher current applications, external buffering or series limiting resistors are recommended to protect the internal switch network.
Is the X9317WS8ZT1 pin-compatible with other members of the X9317 family?
Yes, all X9317 variants - including X9317WS8ZT1, X9317WM8ZT1, and X9317WV8ZT1 - share identical 8-pin SOIC, MSOP, and TSSOP footprints and pinouts. This allows drop-in substitution based on temperature grade or package preference without PCB redesign.
