Product details
Overview
X9313WS-3T2 from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 3-wire serial interface (CS/U/D/INC), nonvolatile wiper position storage, and ±VCC terminal voltage capability. It implements a 31-element resistor array with make-before-break switching, operates from 3V to 5.5V, and delivers 10 kΩ end-to-end resistance with ±20% tolerance for precision analog trimming in embedded control circuits.
For engineers reviewing the X9313WS-3T2 datasheet, X9313WS-3T2 pinout, X9313WS-3T2 application, or X9313WS-3T2 equivalent, this device supports stable power-up recall, low-power standby (500 µA max), temperature-compensated linearity (±1 MI absolute), and industrial-grade operation (–40°C to +85°C) in SOIC-8 packaging.
Technical Context
The X9313WS-3T2 integrates a 5-bit up/down counter, nonvolatile memory for wiper position retention, and a resistor array with 31 matched elements. Its 3-wire interface enables deterministic wiper positioning without clock or data lines beyond CS, U/D, and INC - all edge-triggered and compatible with microcontroller GPIOs.
Wiper movement follows make-before-break switching to prevent open-circuit transients; terminal voltages support ±VCC (–5V to +5V at VCC = 5V), and wiper resistance is specified at 40 Ω (typ) under 5V supply. The device enters standby mode automatically after store completion or CS deassertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance (RTOTAL) | 10 kΩ ±20% - sets full-scale analog range for voltage divider or current-limiting configurations |
| Wiper positions | 32 discrete taps - provides 3.125% resolution per step across full resistance range |
| Supply voltage range | 3V to 5.5V - supports dual-rail systems and mixed-voltage MCU interfacing |
| Terminal voltage range | –VCC to +VCC - enables bipolar signal conditioning (e.g., ±5V rails) |
| Nonvolatile storage endurance | 100,000 write cycles - ensures long-term field calibration stability |
| Power-up behavior | Recalls last stored wiper position - eliminates startup drift in closed-loop systems |
| Standby current | 500 µA max - minimizes quiescent draw during system sleep modes |
Pinout & Package
Package: 8-lead SOIC (Pb-free, RoHS compliant), 3.9 mm × 4.9 mm body, 1.27 mm lead pitch (JEDEC MS-012-AA).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 3V–5.5V; powers internal logic and resistor array bias |
| VSS | Ground reference | Return path for supply and signal currents; must be low-impedance |
| CS | Chip select input | Active-low enable; HIGH initiates nonvolatile store when INC is HIGH |
| U/D | Direction control | Defines wiper increment/decrement direction during INC transitions |
| INC | Increment clock input | Negative-edge triggered; advances wiper one tap per valid transition |
| RH/VH | High terminal | Fixed end of resistor array; voltage range –VCC to +VCC relative to VSS |
| RL/VL | Low terminal | Fixed end opposite RH/VH; same voltage rating and routing constraints |
| RW/VW | Wiper output | Movable tap point; series resistance ≤100 Ω (max) at VCC = 5V |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, contact bounce, and environmental sensitivity of trim pots |
| Nonvolatile wiper position memory | Retains setting for 100 years; enables consistent power-on state without host reinitialization |
| Make-before-break wiper switching | Prevents open-circuit glitches during tap transitions - critical for stable feedback loops |
| Temperature-compensated resistor array | ±300 ppm/°C RTOTAL drift - maintains ratio accuracy across industrial temperature range |
| 3-wire serial interface | Requires only three GPIOs; no clock or data bus overhead - ideal for resource-constrained MCUs |
Applications
| Audio Signal Level Control | DC Power Supply Trim |
|---|---|
|
Use Scenario: Adjusting gain or volume in analog audio paths using microcontroller-based user interface. IC Role / Device Role / Timing Role: Acts as digitally programmable voltage divider between op-amp stages or DAC output and amplifier input.

IC Role / Device Role / Timing Role: Sets R1/R2 ratio in positive-feedback network to define upper/lower trip thresholds. Use Value: Allows dynamic hysteresis adjustment based on operating mode; prevents chatter in noisy sensor inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5171BRMZ-10 | I²C interface, 64-tap resolution, 10 kΩ, ±20% tolerance, 3V–5.5V supply | Requires I²C master; higher resolution but no native 3-wire compatibility | Choose when I²C infrastructure exists and finer granularity is needed over simple GPIO control |
| MCP41010-I/P | SPITM interface, 257-tap resolution, 10 kΩ, ±20% tolerance, 2.7V–5.5V supply | Uses 4-wire SPI (CS/SCK/SDI/SDO); no nonvolatile store on power-down by default | Prefer when existing SPI peripherals are available and external EEPROM or firmware store is acceptable |
Compared with AD5171BRMZ-10 and MCP41010-I/P, the X9313WS-3T2 offers lowest GPIO footprint (3 pins), guaranteed power-up recall without host intervention, and bipolar terminal voltage support - making it optimal for cost-sensitive, low-pin-count industrial analog interfaces.

FAQ
What is the operating temperature range for the X9313WS-3T2?
The X9313WS-3T2 is rated for industrial operation from –40°C to +85°C. This range is confirmed in the Ordering Information table (Page 2) and Recommended Operating Conditions (Page 5) of the FN8177 datasheet. It ensures reliable performance in harsh environments such as factory automation controllers and outdoor instrumentation where thermal cycling occurs.
Does the X9313WS-3T2 retain its wiper position after power loss?
Yes, the X9313WS-3T2 stores the wiper position in nonvolatile memory and recalls it automatically on power-up. This behavior is explicitly stated in the datasheet overview (Page 1), Principles of Operation (Page 3), and confirmed in the Endurance and Data Retention table (Page 6), which specifies 100-year data retention. No external memory or host initialization is required for X9313WS-3T2 to restore its last setting.
Can the X9313WS-3T2 be used with bipolar analog signals?
Yes, the X9313WS-3T2 supports terminal voltages from –VCC to +VCC, enabling direct use with bipolar signals such as ±5V or ±2.5V rails. This is documented in the Absolute Maximum Ratings (Page 5) and Potentiometer Characteristics table (Page 5), where VH and VL ratings are specified as –VCC to +VCC. The device's CMOS construction and rail-to-rail wiper operation make it suitable for AC-coupled or dual-supply analog paths.
What is the maximum wiper current rating for the X9313WS-3T2?
The X9313WS-3T2 has a maximum wiper current rating of ±4.4 mA, as specified in the Recommended Operating Conditions table (Page 5). This limit applies regardless of RTOTAL value and must be observed to avoid degradation of wiper switch reliability. Exceeding this current may accelerate wear or cause temporary resistance shift due to self-heating of the 31-element array.
Is the X9313WS-3T2 pin-compatible with other X9313 variants in SOIC-8 package?
Yes, the X9313WS-3T2 shares identical pinout and SOIC-8 footprint (M8.15 drawing) with all X9313 variants in that package, including X9313USZ, X9313USIZ, and X9313WSIZ. Pin assignments - VCC, VSS, CS, U/D, INC, RH/VH, RL/VL, RW/VW - are standardized across the family per Table 1 (Page 3) and Pinouts diagram (Page 3). Only electrical parameters (e.g., RTOTAL, VCC range, temp grade) differ between variants.
