Product details
Overview
X9317ZS8I-2.7T1 from Renesas Electronics is a digitally controlled potentiometer (XDCP™) with 100 wiper tap points, nonvolatile wiper position storage, and 3-wire serial up/down interface. It features 10 kΩ end-to-end resistance, operates from 2.7 V to 5.5 V, and delivers ±1% absolute linearity for precision voltage divider or variable resistor applications in bias control and trim circuits.
For engineers reviewing the X9317ZS8I-2.7T1 datasheet, X9317ZS8I-2.7T1 pinout, X9317ZS8I-2.7T1 application, or X9317ZS8I-2.7T1 equivalent, key selection considerations include its 2.7–5.5 V supply range, MSOP-8 package, -40°C to +85°C industrial temperature rating, nonvolatile store/recall capability, and low 5 µA standby current.
Technical Context
The X9317ZS8I-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 discrete wiper positions, with position updates triggered by negative-edge INC pulses under active CS control.
Wiper position is retained in nonvolatile memory across power cycles and recalled within 5 µs after power-up. The device supports both three-terminal potentiometer (voltage divider) and two-terminal variable resistor (current control) configurations, with RH/RL terminals rated for 0 V to VCC and RW exhibiting 200 Ω typical wiper resistance at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - defines full-scale analog adjustment range and load interaction in voltage divider designs |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct compatibility with 3.3 V and 5 V systems without level-shifting |
| Wiper Tap Resolution | 100 positions (0–99) - provides 1% step resolution for fine-grained analog tuning |
| Absolute Linearity | ±1 MI (Minimum Increment) - ensures ≤1% deviation from ideal voltage division across full range |
| Standby Current | <5 µA - minimizes quiescent power in battery-powered or always-on trim applications |
| Nonvolatile Endurance | 100,000 data changes per bit - supports long-term field calibration and user-adjustable settings |
| Temperature Range | -40°C to +85°C - qualified for industrial environments including automotive cabin and industrial control |
| Wiper Resistance | 200 Ω typical at 5 V - limits insertion error and signal attenuation in high-impedance feedback paths |
Pinout & Package
Package: 8-lead MSOP (Moisture Sensitivity Level 1, RoHS-compliant, JEDEC MO-187-AA compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control signal; toggling moves wiper up/down based on U/D state |
| 2 (U/D) | Direction control input | Logic level determines wiper movement direction during INC transition |
| 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; must be stable and low-impedance |
| 5 (RW) | Wiper output | Movable terminal; delivers intermediate voltage/current; series resistance ≤400 Ω at 2.7 V |
| 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) | Power supply | 2.7–5.5 V CMOS supply; powers logic, memory, and resistor array; decoupling required |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, contact bounce, and environmental sensitivity of traditional pots |
| Nonvolatile wiper position storage | Recalls last-set tap position on power-up-no external EEPROM or initialization firmware needed |
| 3-wire serial up/down interface | Requires only CS, U/D, and INC signals-no clock or data lines simplifies MCU GPIO usage |
| Temperature-compensated resistor array | ±300 ppm/°C total resistance drift enables stable trim over industrial temperature range |
| Low-power CMOS design | 5 µA standby current and 80 µA active current support energy-constrained embedded systems |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions-critical for stable feedback loop operation |

Use Value: Low 200 Ω wiper resistance minimizes offset drift contribution; ±300 ppm/°C TC ensures thermal stability over operating range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5241BRMZ10 | I²C interface, 128 taps, 10 kΩ, 2.7–5.5 V, ±30% RTOTAL tolerance | Requires I²C host; lacks nonvolatile recall on power-up (defaults to mid-scale) | Choose for systems already using I²C infrastructure and where mid-scale default is acceptable |
| MCP41010-I/P | SPI interface, 257 taps, 10 kΩ, 2.7–5.5 V, ±20% RTOTAL, volatile-only memory | No nonvolatile storage; requires external MCU to reprogram wiper at boot | Choose when higher resolution (257 taps) is prioritized over autonomous power-up behavior |
Compared with AD5241BRMZ10 and MCP41010-I/P, the X9317ZS8I-2.7T1 uniquely combines 3-wire simplicity, guaranteed power-up recall, and industrial temperature rating-reducing firmware overhead and improving system robustness in unattended deployments.

FAQ
What is the supply voltage range for the X9317ZS8I-2.7T1?
The X9317ZS8I-2.7T1 operates from 2.7 V to 5.5 V, making it compatible with both 3.3 V and 5 V logic systems. This wide range eliminates the need for external voltage translation and supports direct connection to common MCU I/O rails. The "-2.7" suffix explicitly denotes this extended low-voltage capability, distinct from the standard 4.5–5.5 V version.
Does the X9317ZS8I-2.7T1 retain its wiper position after power cycling?
Yes, the X9317ZS8I-2.7T1 stores the wiper position in nonvolatile memory and automatically recalls it within 5 µs of power-up. This behavior is guaranteed across its -40°C to +85°C operating range and requires no external components or host intervention-enabling reliable, repeatable analog settings in standalone or battery-powered systems.
What package type is used for the X9317ZS8I-2.7T1?
The X9317ZS8I-2.7T1 is housed in an 8-lead MSOP (Mini Small Outline Package), per JEDEC MO-187-AA. Its dimensions are 3.0 mm × 3.0 mm × 1.1 mm max height, with 0.65 mm lead pitch. This compact, surface-mount package supports high-density PCB layouts and is RoHS-compliant with matte tin (e3) termination.
How many wiper positions does the X9317ZS8I-2.7T1 support?
The X9317ZS8I-2.7T1 provides exactly 100 discrete wiper tap positions (0 through 99), corresponding to a 1% resolution step size across its 10 kΩ end-to-end resistance. This resolution is fixed and confirmed by its 7-bit counter architecture and 99-resistor-element array, enabling predictable, repeatable analog adjustments.
What is the absolute linearity specification for the X9317ZS8I-2.7T1?
The X9317ZS8I-2.7T1 has an absolute linearity of ±1 MI (Minimum Increment), where MI = (VRH – VRL) / 99. This means the actual wiper voltage deviates by no more than ±1% of full-scale span from the ideal linear transfer function-critical for precision gain/offset trimming and bias control where monotonicity and accuracy are mandatory.
