Product details
Overview
X9317ZS8Z 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, operating from 2.7V to 5.5V with ±20% end-to-end resistance tolerance and <5µA standby current.
For engineers reviewing the X9317ZS8Z datasheet, X9317ZS8Z pinout, X9317ZS8Z application, or X9317ZS8Z equivalent, this device supports repeatable, power-loss-resilient bias control in LCDs, laser diodes, voltage regulators, and amplifier gain/offset circuits - requiring confirmation of RH/RW/RL terminal usage, CS/U/D/INC timing compliance, and 8-lead SOIC package integration.
Technical Context
The X9317ZS8Z integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 100 discrete taps. Its "make-before-break" wiper switching ensures continuity during transitions, while temperature-compensated resistor elements deliver ±300 ppm/°C total resistance drift and ±20 ppm/°C ratiometric stability.
Control logic responds to negative-edge-triggered INC pulses under active CS low, with U/D determining direction. A HIGH-to-HIGH CS transition with INC HIGH initiates nonvolatile store; wiper position is automatically recalled at power-up. The device exhibits 100,000 write cycles and 100-year data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - defines full-scale analog range and load interaction in voltage divider or current-limiting configurations |
| Wiper Tap Count | 100 positions - enables 1% resolution adjustment without external DAC or microcontroller interpolation |
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-supply operation across industrial and commercial rails including 3.3 V and 5 V systems |
| Standby Current | <5 µA - minimizes quiescent power in battery-backed or energy-sensitive applications |
| Nonvolatile Store Time | 5–10 ms - determines minimum system hold time after wiper adjustment before CS deactivation to ensure reliable recall |
| Wiper Resistance | 200 Ω typical (at 5 V), 400 Ω typical (at 2.7 V) - impacts signal integrity and loading in high-impedance feedback paths |
| Temperature Coefficient | ±300 ppm/°C (absolute), ±20 ppm/°C (ratiometric) - ensures stable voltage division over -40°C to +85°C industrial range |
| Interface Type | 3-wire serial (CS, U/D, INC) - eliminates need for I²C/SPI peripherals; compatible with GPIO-driven microcontrollers |
Pinout & Package
Package: 8-lead 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 line; toggling moves wiper up/down per U/D state; requires tCYC ≥ 2 µs |
| 2: U/D | Direction control input | Logic level sets wiper movement direction during INC transitions; may be changed dynamically under CS low |
| 3: RH | High terminal | Fixed end of resistor array; connected to higher potential in voltage divider; not necessarily highest voltage node |
| 4: VSS | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise-sensitive analog use |
| 5: RW | Wiper terminal | Movable tap output; series resistance ≤400 Ω at 2.7 V affects gain accuracy in op-amp feedback networks |
| 6: RL | Low terminal | Fixed end of resistor array; connected to lower potential in voltage divider; defines bottom rail of resistive ladder |
| 7: CS | Chip select | Active-low enable; wiper updates only when CS = LOW; HIGH with INC = HIGH triggers nonvolatile store |
| 8: VCC | Supply voltage | 2.7–5.5 V power input; ICC1 ≤ 80 µA during active adjustment; ISB ≤ 5 µA in standby |
Key Features
| Feature | Design Value |

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 nominal, 500 ppm/°C TC | Requires I²C master; higher resolution but less stable ratiometric performance (±50 ppm/°C) | Choose for systems already using I²C infrastructure and needing finer granularity than 1% steps |
| MCP41010-I/P | SPI interface, 256-tap, 10 kΩ, 100 ppm/°C TC, volatile-only memory | No nonvolatile store - wiper resets to mid-scale on power-up unless externally reprogrammed | Choose when SPI is preferred and system firmware can guarantee initialization before analog operation |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9317ZS8Z offers deterministic power-up behavior without host intervention, simpler GPIO-based control, and superior ratiometric stability - making it optimal for unattended, calibration-critical analog biasing where reliability outweighs interface flexibility.

FAQ
What is the operating temperature range for the X9317ZS8Z?
The X9317ZS8Z is specified for 0°C to +70°C commercial operation. Its electrical parameters-including end-to-end resistance tolerance, wiper resistance, and timing-guarantee full functionality across this range. The device uses temperature-compensated resistor elements to maintain ±20 ppm/°C ratiometric stability, ensuring consistent voltage division in ambient-varying environments like consumer displays and industrial controls. X9317ZS8Z does not support extended industrial (-40°C to +85°C) operation; for that range, consider X9317WS8IZ.
How does the X9317ZS8Z store and recall wiper position?
The X9317ZS8Z stores wiper position in nonvolatile memory when CS transitions HIGH while INC is held HIGH. This store cycle takes 5–10 ms and retains data for 100 years. On subsequent power-up, the stored value is automatically loaded into the wiper counter, positioning RW at the last-saved tap. No external controller action is required. This behavior makes X9317ZS8Z ideal for applications needing guaranteed boot-time calibration, such as LCD bias or regulator output settings.
Can the X9317ZS8Z be used as a two-terminal variable resistor?
Yes, the X9317ZS8Z supports two-terminal operation by connecting either RH or RL to RW and using the remaining terminal with RW as the variable resistance element. In this mode, resistance varies from near-zero (wiper at same terminal) to RTOTAL (wiper at opposite end). Designers must account for wiper resistance (≤400 Ω at 2.7 V) and ensure current stays within ±4.4 mA limits. This configuration is commonly used for laser diode bias current adjustment and op-amp gain control where one end of the potentiometer is grounded or tied to a fixed rail.
What is the maximum allowable voltage across RH and RL terminals of the X9317ZS8Z?
The absolute maximum voltage between RH and RL terminals is ±6 V, as specified in the Absolute Maximum Ratings table. However, for reliable operation within datasheet limits, the voltage applied across RH and RL must remain within the supply rails: V(RH) – V(RL) ≤ VCC – VSS, with VCC = 2.7–5.5 V. Exceeding VCC risks violating the RH/RL terminal voltage specification (0 V to VCC), potentially damaging internal switches. For example, with VCC = 5 V, RH and RL must stay between 0 V and 5 V relative to VSS - never exceeding that differential.
Does the X9317ZS8Z require external pull-up or pull-down resistors on its control pins?
No, the X9317ZS8Z does not require external pull-up or pull-down resistors on CS, U/D, or INC. Its inputs have CMOS-compatible thresholds (VIH = 0.7×VCC, VIL = 0.1×VCC) and leakage current ≤±10 µA, allowing direct connection to microcontroller GPIOs. However, to prevent spurious wiper movement during power-up, Renesas recommends holding CS and INC HIGH before applying VCC - a practice easily implemented with weak internal MCU pull-ups or explicit initialization code. This ensures X9317ZS8Z remains in standby until intentionally enabled.
