Product details
Overview
X9317TS8Z from Renesas Electronics is a digitally controlled potentiometer (XDCP™) implementing a 99-element resistor array with 100 discrete 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 operating from 2.7V to 5.5V supply.
For engineers reviewing the X9317TS8Z datasheet, X9317TS8Z pinout, X9317TS8Z application, or X9317TS8Z equivalent, this device supports critical calibration tasks including LCD bias control, laser diode current setting, gain/offset trim, and adjustable voltage regulator feedback-requiring verified wiper repeatability, <5µA standby current, ±20% end-to-end resistance tolerance, and 100-year data retention.
Technical Context
The X9317TS8Z integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 100 taps. Its "make-before-break" switching ensures continuity during wiper transitions, while temperature-compensated resistor elements deliver ±300 ppm/°C total resistance drift and ±20 ppm/°C ratiometric stability.
Control is executed via CS (chip select), U/D (direction), and edge-triggered INC inputs. A HIGH-to-LOW transition on INC moves the wiper; CS returning HIGH with INC HIGH initiates nonvolatile store. Wiper resistance is 200Ω typical at 5V and 400Ω typical at 2.7V, with 10mW power rating for RTOTAL ≥10kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10kΩ ±20% - defines full-scale analog range and sets minimum load impedance for stable voltage division |
| Wiper Tap Count | 100 positions - enables 1% resolution per step for fine-grained analog adjustment without external DAC |
| Supply Voltage Range | 2.7V to 5.5V - supports single-supply operation across industrial and commercial logic families |
| Standby Current | <5µA - minimizes quiescent power in battery-backed or energy-sensitive systems |
| Nonvolatile Retention | 100 years - guarantees factory-set or field-trimmed values persist over product lifetime without refresh |
| Wiper Resistance | 200Ω (typ, VCC=5V) - limits voltage error in low-impedance feedback paths and affects noise coupling |
| Temperature Coefficient | ±300 ppm/°C (absolute), ±20 ppm/°C (ratiometric) - ensures stable gain/offset over -40°C to +85°C |
Pinout & Package
Package: 8-lead TSSOP (RoHS-compliant, JEDEC MO-153 AC, M8.173 drawing). Body dimensions: 4.40mm × 3.0mm × 1.20mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control line; toggling moves wiper one tap in direction set by U/D |
| 2 (U/D) | Direction control input | Logic level determines wiper movement direction (HIGH = up, LOW = down) during INC transition |
| 3 (RH) | High terminal | Fixed end of resistor array; connected to highest potential in voltage divider configuration |
| 4 (VSS) | Ground reference | Return path for all internal circuitry and external analog signals; must be low-impedance |
| 5 (RW) | Wiper output | Movable terminal delivering intermediate voltage/current; series resistance impacts signal fidelity |
| 6 (RL) | Low terminal | Fixed end of resistor array; connected to lowest potential (e.g., ground or negative rail) |
| 7 (CS) | Chip select | Active-low enable; HIGH disables device and triggers nonvolatile store when INC is also HIGH |
| 8 (VCC) | Supply voltage | Power source for logic and analog sections; requires local 0.1µF bypass capacitor to VSS |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, contact bounce, and vibration sensitivity inherent in electro-mechanical pots |
| 3-wire serial interface | Requires only CS, U/D, and INC signals-no clock or data lines-simplifying MCU GPIO usage |
| Nonvolatile wiper storage | Retains last programmed position across power cycles, enabling consistent startup behavior without host reinitialization |
| Temperature-compensated array | Reduces drift-induced calibration errors in ambient-varying environments such as industrial enclosures or automotive cabins |
| Low-power CMOS design | Enables integration into always-on subsystems (e.g., sensor bias networks) with negligible impact on system battery life |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ10 | I²C interface, dual-channel, 256-tap resolution, 10kΩ nominal, 500ppm/°C tempco | Requires I²C master; better resolution but higher tempco; no nonvolatile store per channel | Select when dual independent pots or I²C bus compatibility are required; accept higher drift and volatile defaults |
| MCP41010-I/P | SPITM interface, 256-tap, 10kΩ, 100-year NV retention, 500ppm/°C tempco, 5.5V max | Uses SPI instead of 3-wire up/down; identical retention but higher resistance drift and different timing constraints | Choose for SPI-native systems needing higher resolution; verify timing margins for INC-equivalent clock edges |
Compared with X9317TS8Z, AD5243BRMZ10 offers dual channels and I²C simplicity but lacks per-device nonvolatile store and exhibits higher temperature drift; MCP41010-I/P provides finer resolution and SPI compatibility but requires stricter clock timing and delivers less stable ratiometric performance over temperature.

FAQ
What is the operating temperature range for the X9317TS8Z?
The X9317TS8Z is rated for industrial operation from -40°C to +85°C. This range is validated across all electrical specifications including end-to-end resistance tolerance, wiper resistance, and nonvolatile memory endurance. The device maintains ±20 ppm/°C ratiometric temperature coefficient within this span, ensuring stable analog performance in demanding thermal environments.
Does the X9317TS8Z require external components for basic operation?
Yes-the X9317TS8Z requires a 0.1µF ceramic bypass capacitor between VCC and VSS, placed as close as possible to the package pins. No pull-up or pull-down resistors are needed on CS, U/D, or INC, as internal logic thresholds are defined relative to VCC and VSS. External RC filtering on RW is optional and application-dependent.
How is nonvolatile storage triggered on the X9317TS8Z?
Nonvolatile storage on the X9317TS8Z occurs automatically when CS transitions from LOW to HIGH while the INC input is held HIGH. This sequence writes the current wiper position to EEPROM. The store cycle takes 5–10ms, during which the device draws elevated current and ignores further INC transitions until completion.
Can the X9317TS8Z be used in a two-terminal configuration?
Yes-the X9317TS8Z supports two-terminal operation by connecting either RH or RL to RW externally and using the remaining terminal plus RW as the variable resistor. In this mode, the device functions as a digitally adjustable rheostat with 100-step resolution and retains its 100-year data retention and low standby current characteristics.
What is the maximum wiper current rating for the X9317TS8Z?
The X9317TS8Z specifies a maximum wiper current (IW) of ±4.4mA under all operating conditions. Exceeding this limit risks irreversible damage to the internal switch matrix. For applications requiring higher current, external buffer amplifiers or MOSFET-based current boost stages must be used-X9317TS8Z itself is not rated for power switching.
