Product details
Overview
X9313WMI-3T1 from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 10 kΩ end-to-end resistance, ±VCC terminal voltage capability, and nonvolatile wiper position storage. It functions as a solid-state three-terminal potentiometer or two-terminal variable resistor in analog signal conditioning circuits requiring stable, repeatable resistance adjustment across power cycles.
For engineers reviewing the X9313WMI-3T1 datasheet, X9313WMI-3T1 pinout, X9313WMI-3T1 application, or X9313WMI-3T1 equivalent, key selection criteria include its 3-wire serial interface timing (tIW = 5 µs), industrial temperature range (–40°C to +85°C), MSOP-8 package footprint, and compatibility with 3 V to 5.5 V supply rails.
Technical Context
The X9313WMI-3T1 implements a 31-element resistor array with make-before-break wiper switching, enabling glitch-free tap transitions. Its 5-bit up/down counter drives a decoder that selects one of 32 wiper positions, with direction controlled by the U/D input and step triggered on INC's negative edge.
Wiper position is stored into nonvolatile memory when CS rises while INC is HIGH (tCPH = 20 ms store cycle), and automatically recalled at power-up. The device operates in low-power standby (500 µA max) when deselected, and supports terminal voltages from –VCC to +VCC with ±10 V differential limit for the X9313W variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance (RTOTAL) | 10 kΩ ±20% - defines full-scale analog gain/attenuation range and current-handling capability in voltage divider or current-limiting configurations |
| Wiper resolution | 32 taps (31 segments) - provides 3.125% per-step resistance increment; minimum increment = RTOTAL/31 ≈ 322 Ω |
| Supply voltage range | 3 V to 5.5 V - enables direct interfacing with 3.3 V and 5 V logic systems without level-shifting |
| Operating temperature | –40°C to +85°C - qualified for industrial environments including motor control, instrumentation, and embedded sensor interfaces |
| Wiper resistance (RW) | 40 Ω typical at VCC = 5 V - contributes negligible series error in precision voltage division applications |
| Nonvolatile endurance | 100,000 data changes per bit - supports long-term field calibration and user-adjustable settings over product lifetime |
| Power-up behavior | Recalls last stored wiper position - eliminates startup drift and ensures deterministic analog output at system boot |
Pinout & Package
Package: 8-lead MSOP (Mo-187-AA compliant), 3.0 mm × 3.0 mm body, 0.65 mm pitch, RoHS-compliant matte tin termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply rail | Accepts 3 V to 5.5 V; powers internal logic, memory, and resistor array; must be stabilized before CS/INC activation |
| VSS | Ground reference | Common return for supply, logic inputs, and potentiometer terminals; requires low-impedance connection to minimize noise coupling |
| RH/VH | High terminal | Fixed end of resistor array; voltage polarity relative to wiper depends on U/D state, not absolute potential |
| RL/VL | Low terminal | Fixed opposite end of resistor array; forms complete resistive path with RH/VH; supports bidirectional voltage swing |
| RW/VW | Wiper terminal | Movable contact point; delivers tapped voltage or variable resistance; series resistance ≤100 Ω ensures minimal loading error |
| CS | Chip select | Active-low enable; initiates wiper movement when LOW; triggers nonvolatile store on rising edge if INC = HIGH |
| U/D | Direction control | Defines wiper increment/decrement direction during INC toggles; may be changed dynamically while CS = LOW |
| INC | Increment clock | Negative-edge-triggered; advances wiper one tap per valid edge; timing critical (tIL/tIH ≥ 1 µs, tCYC ≥ 2 µs) |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, vibration sensitivity, and contact bounce-enables >100,000 adjustment cycles with stable TCR (±300 ppm/°C) |
| 3-wire serial interface | Requires only CS, U/D, and INC signals-reduces MCU GPIO count vs. I²C/SPI; no address decoding or clock stretching overhead |
| Nonvolatile wiper storage | Retains last position for 100 years; restores calibrated setting at every power-on-critical for factory-trimmed sensor offsets or audio presets |
| ±VCC terminal voltage range | Supports bipolar signal paths (e.g., ±5 V op-amp stages); enables use in AC-coupled amplifiers and dual-supply comparators |
| Temperature-compensated array | Ensures <±1 MI absolute linearity and <±0.2 MI relative linearity across –40°C to +85°C-maintains accuracy in unregulated thermal environments |
| Low standby current | 500 µA max at VCC = 5 V-minimizes quiescent power in battery-operated or energy-harvesting systems during idle periods |

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, 2.7–5.5 V supply | Requires I²C host support; higher resolution but lacks ±VCC terminal swing capability | Preferred where bus-based configuration and finer granularity outweigh need for bipolar signal handling |
| MCP41010-I/P | SPITM interface, 257-tap resolution, 10 kΩ, ±20% tolerance, 2.7–5.5 V supply | Higher resolution and faster update rate (tWIPER < 1 µs), but volatile wiper position (no power-up recall) | Chosen when rapid dynamic adjustment is prioritized over nonvolatile retention |

FAQ
What is the supply voltage range supported by the X9313WMI-3T1?
The X9313WMI-3T1 operates from 3 V to 5.5 V, making it compatible with both 3.3 V and 5 V logic systems. This range is explicitly specified in the "Recommended Operating Conditions" table on page 5 of the FN8177 datasheet. Operation outside this range risks violating absolute maximum ratings and may cause unreliable wiper positioning or memory corruption in the X9313WMI-3T1.
Does the X9313WMI-3T1 retain its wiper position after power loss?
Yes, the X9313WMI-3T1 stores the wiper position in nonvolatile memory and recalls it automatically upon power-up. This behavior is guaranteed for 100 years per the datasheet's "Endurance and Data Retention" section. The store operation is triggered by raising CS while INC is HIGH, and the X9313WMI-3T1 will restore that exact value at every subsequent power cycle.
Can the X9313WMI-3T1 be used with bipolar analog signals?
Yes-the X9313WMI-3T1 supports terminal voltages from –VCC to +VCC, and its X9313W variant has a ±10 V differential limit (|VH – VL| ≤ 10 V). This allows direct use in bipolar op-amp stages, AC-coupled filters, and comparator hysteresis networks without external level-shifting, a capability confirmed in the "Potentiometer Characteristics" table on page 5 of the X9313WMI-3T1 datasheet.
What package type is used for the X9313WMI-3T1?
The X9313WMI-3T1 uses an 8-lead MSOP package (package drawing M8.118), measuring 3.0 mm × 3.0 mm with 0.65 mm lead pitch. This is verified in the "Ordering Information" table on page 2 of the FN8177 datasheet, where "X9313WMIZ-3*" corresponds to the industrial-grade MSOP variant, and the "T1" suffix denotes tape-and-reel packaging per TB347.
How many wiper positions does the X9313WMI-3T1 provide?
The X9313WMI-3T1 provides 32 discrete wiper tap positions, implemented via a 31-resistor ladder network. Each step represents a minimum increment (MI) of RTOTAL/31 ≈ 322 Ω for the 10 kΩ version. This resolution is documented in the "Features" section (page 1) and quantified in the "Potentiometer Characteristics" table (page 5) of the X9313WMI-3T1 datasheet.
