Product details
Overview
X9317ZV8-2.7T1 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 over -40°C to +85°C - enabling precision DC bias adjustment in analog signal chains.
For engineers reviewing the X9317ZV8-2.7T1 datasheet, X9317ZV8-2.7T1 pinout, X9317ZV8-2.7T1 application, or X9317ZV8-2.7T1 equivalent, key selection criteria include its 2.7 V minimum supply voltage, MSOP-8 package, nonvolatile store-and-recall capability, low 5 µA standby current, and temperature-compensated resistor array for stable trim across industrial environments.
Technical Context
The X9317ZV8-2.7T1 implements a 99-element resistor array with make-before-break wiper switching, driven by a 7-bit up/down counter controlled via CS, U/D, and edge-triggered INC inputs. Its nonvolatile memory retains wiper position for 100 years and supports 100,000 write cycles.
It functions as either a three-terminal voltage divider (RH–RW–RL) or two-terminal variable resistor (RW–RL or RW–RH), with wiper resistance of 200 Ω (typ.) at 5 V and 400 Ω (typ.) at 2.7 V. Ratiometric temperature coefficient is ±20 ppm/°C, ensuring stable ratio tracking under thermal drift.
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 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 divider output across full range |
| Standby Current | <5 µA - minimizes power impact in always-on or battery-backed calibration circuits |
| Nonvolatile Retention | 100 years - guarantees factory-set or field-trimmed values persist through decades of operation |
| Wiper Resistance | 400 Ω (typ.) at 2.7 V - limits loading error when driving high-impedance nodes in low-voltage designs |
Pinout & Package
Package: 8-lead MSOP (Moisture Sensitivity Level 1, RoHS-compliant, JEDEC MO-187-AA compliant; dimensions per drawing M8.118).
| 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 sets wiper movement direction (HIGH = up, LOW = down) during INC transitions |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher potential node in voltage divider configuration |
| 4 (VSS) | Ground reference | Primary return path for internal logic and resistor array; must be low-impedance |
| 5 (RW) | Wiper terminal | Movable contact point; output node whose voltage varies linearly between RH and RL potentials |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential node (e.g., ground or negative rail) |
| 7 (CS) | Chip select | Active-low enable; HIGH initiates nonvolatile store when INC is also HIGH |
| 8 (VCC) | Supply voltage | Power source for logic and resistor array; supports 2.7–5.5 V operation with <5 µA standby draw |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, contact bounce, and environmental sensitivity of analog trim pots |
| 3-wire serial up/down interface | Requires only three GPIOs - no SPI/I²C controller needed - simplifying MCU integration |
| Nonvolatile wiper position storage | Automatically restores last-trimmed setting on power-up, eliminating boot-time recalibration |
| Temperature-compensated resistor array | ±20 ppm/°C ratiometric TC ensures stable voltage division ratio across -40°C to +85°C |
| Low-power CMOS design | 5 µA standby current enables use in energy-sensitive applications like portable instrumentation |

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, 2.7–5.5 V; no nonvolatile store on power-up | Requires external EEPROM or host-initiated restore; better resolution but higher interface overhead | Choose when I²C bus availability and finer 0.4% step resolution outweigh need for autonomous power-up recall |
| MCP41010-I/P | SPI interface, 256-tap, 10 kΩ, 2.7–5.5 V; volatile wiper register only (no NV memory) | Needs host MCU to reinitialize wiper position at every power cycle; no autonomous recall | Choose when SPI is preferred and system-level firmware handles all trim persistence |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9317ZV8-2.7T1 uniquely combines 3-wire simplicity, guaranteed power-up recall, and industrial-grade temperature stability - reducing firmware complexity and improving long-term calibration integrity without added components.

FAQ
What is the operating temperature range for the X9317ZV8-2.7T1?
The X9317ZV8-2.7T1 is rated for −40°C to +85°C, qualifying it for industrial and extended-temperature applications. This range applies to all specified electrical parameters including end-to-end resistance tolerance, linearity, and nonvolatile memory endurance - verified per Renesas FN8183 Rev.10.01 test conditions.
Does the X9317ZV8-2.7T1 retain its wiper position after power loss?
Yes, the X9317ZV8-2.7T1 stores the wiper position in nonvolatile memory and automatically recalls it on power-up. This behavior is guaranteed across its full temperature range and supported by 100-year data retention and 100,000 write-cycle endurance - confirmed in the device's DC Electrical Specifications table.
What package type does the X9317ZV8-2.7T1 use?
The X9317ZV8-2.7T1 uses an 8-lead MSOP package (JEDEC MO-187-AA compliant, drawing M8.118), with body dimensions 3.0 mm × 3.0 mm × 1.1 mm max and 0.65 mm lead pitch. It is RoHS-compliant and moisture-sensitive level 1 - compatible with standard reflow profiles per J-STD-020.
How does the 3-wire interface of the X9317ZV8-2.7T1 work?
The X9317ZV8-2.7T1 uses CS (chip select), U/D (up/down), and INC (increment) signals. With CS low, each negative edge on INC moves the wiper one step in the direction set by U/D. A store operation occurs when CS rises while INC is high - writing the current wiper position to nonvolatile memory.
Is the X9317ZV8-2.7T1 compatible with 3.3 V logic systems?
Yes, the X9317ZV8-2.7T1 operates from 2.7 V to 5.5 V and accepts logic inputs with VIH ≥ 0.7 × VCC and VIL ≤ 0.1 × VCC. At 3.3 V supply, VIH is ≥ 2.31 V and VIL is ≤ 0.33 V - fully compatible with standard 3.3 V CMOS outputs and inputs without level translation.
