Product details
Overview
X9317WS8IZ-2.7 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 operates from 2.7V to 5.5V, offers 10kΩ end-to-end resistance, ±1% absolute linearity, and <5µA standby current. It functions as a three-terminal voltage divider or two-terminal variable resistor for precision analog trimming in industrial-grade systems.
For engineers reviewing the X9317WS8IZ-2.7 datasheet, X9317WS8IZ-2.7 pinout, X9317WS8IZ-2.7 application, or X9317WS8IZ-2.7 equivalent, this page delivers verified electrical specs, SOIC-8 package mapping, real-world use cases including LCD bias control and laser diode bias adjustment, and two validated alternative parts with documented functional differences.
Technical Context
The X9317WS8IZ-2.7 integrates a 7-bit up/down counter, decoder, nonvolatile memory, and solid-state resistor array with make-before-break wiper switching. Its control logic responds to CS (chip select), U/D (direction), and edge-triggered INC (increment) signals - no clock required.
Wiper position is stored on CS↑ while INC = HIGH, recalled automatically at power-up. The device maintains ratiometric temperature coefficient of ±20 ppm/°C and supports operation across –40°C to +85°C, with RTOTAL tolerance of ±20% and wiper resistance ≤400Ω at 5V (≤1000Ω at 2.7V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10kΩ ±20% - defines full-scale analog range for voltage division or current limiting |
| Supply Voltage Range | 2.7V to 5.5V - enables direct compatibility with 3.3V and 5V systems without level shifting |
| Wiper Tap Resolution | 100 positions (0–99) - provides 1% step resolution for fine analog calibration |
| Absolute Linearity | ±1 MI - ensures maximum deviation of ±1/99 of full-scale voltage across entire range |
| Standby Current | <5µA - minimizes quiescent power in battery-backed or always-on embedded systems |
| Nonvolatile Storage | 100-year data retention, 100,000 write cycles - eliminates need for external EEPROM or MCU backup |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including motor drives and instrumentation |
Pinout & Package
Package: 8-lead narrow-body SOIC (M8.15E), RoHS-compliant, Pb-free, moisture sensitivity level per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment input | Negative-edge-triggered control signal; toggling moves wiper up/down based on U/D state |
| 2 (U/D) | Up/down direction control | Logic level sets wiper movement direction during INC transitions; stable during CS = LOW |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher potential in voltage divider configuration |
| 4 (VSS) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity |
| 5 (RW) | Wiper terminal | Movable contact point; output node with ≤400Ω series resistance at 5V, ≤1000Ω at 2.7V |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential (e.g., ground or negative rail) |
| 7 (CS) | Chip select | Active-low enable; stores wiper position to NV memory when CS↑ while INC = HIGH |
| 8 (VCC) | Supply voltage | Power input for logic and analog sections; supports 2.7V–5.5V with <80µA active current |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Retains last-set tap position across power cycles - eliminates startup recalibration in field-deployed equipment |
| 3-wire serial interface | No clock or data lines required - simplifies MCU GPIO usage and reduces BOM count vs. SPI/I²C DCPs |
| Make-before-break wiper switching | Prevents open-circuit transients during tap changes - critical for stable biasing in sensitive analog circuits |
| Temperature-compensated resistor array | ±20 ppm/°C ratiometric TC - maintains voltage division ratio stability over industrial temperature range |
| Low-power CMOS design | Sub-5µA standby current - extends battery life in portable instrumentation and IoT sensor nodes |

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 taps, 10kΩ, ±30% RTOTAL tolerance | Requires I²C host; lacks nonvolatile recall on power-up (needs external memory or MCU initialization) | Preferred when dual-pot functionality or standard digital bus integration is required over standalone trim simplicity |
| MCP45HV51-103E/MS | High-voltage (up to 36V) operation, SPI interface, 256 taps, 10kΩ, volatile-only memory | Supports higher RH–RL voltage differentials but requires continuous MCU refresh or external NV storage | Chosen for high-side biasing in industrial power supplies where >5.5V terminal voltage is needed |
Compared with AD5243BRMZ10 and MCP45HV51-103E/MS, the X9317WS8IZ-2.7 delivers autonomous power-up behavior and minimal GPIO overhead - critical for cost-sensitive, single-function trimming where reliability and zero-firmware dependency are prioritized over multi-channel or high-voltage capability.

FAQ
What is the operating voltage range for the X9317WS8IZ-2.7?
The X9317WS8IZ-2.7 operates from 2.7V to 5.5V, supporting both 3.3V and 5V logic systems without external regulation. This range is explicitly defined in the Absolute Maximum Ratings and Potentiometer Specifications tables of the FN8183 Rev.10.01 datasheet, with full parameter validity across the –40°C to +85°C temperature range.
Does the X9317WS8IZ-2.7 retain its wiper position after power loss?
Yes, the X9317WS8IZ-2.7 stores the wiper position in nonvolatile memory and automatically recalls it on power-up. This function is confirmed in the device block diagram, Principles of Operation section, and Electrical Specifications - with 100-year data retention and 100,000 write cycles specified in the datasheet.
How many wiper tap positions does the X9317WS8IZ-2.7 provide?
The X9317WS8IZ-2.7 provides exactly 100 wiper tap positions (0 through 99), corresponding to a 99-resistor-element array. This is stated in the title, Features list, and Pin Descriptions section of the FN8183 datasheet, and directly determines its 1% resolution capability.
What package type is used for the X9317WS8IZ-2.7?
The X9317WS8IZ-2.7 uses an 8-lead narrow-body SOIC package (JEDEC MS-012, Renesas drawing M8.15E). This is unambiguously specified in the Ordering Information table on page 2 of FN8183 Rev.10.01, with full mechanical dimensions provided on page 13.
Can the X9317WS8IZ-2.7 be used as a two-terminal variable resistor?
Yes, the X9317WS8IZ-2.7 can be configured as a two-terminal variable resistor by connecting either RH or RL to RW, leaving the unused terminal open. This usage mode is explicitly supported in the Applications section (page 1) and illustrated in Figure 4 ("Two Terminal Variable Resistor") of the FN8183 datasheet.
