Product details
Overview
X9313WMI-3 from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 10kΩ end-to-end resistance, 3-wire serial interface (CS/U/D/INC), nonvolatile wiper position storage, and ±VCC terminal voltage capability. It operates from 3V to 5.5V and is used for precision analog trimming in voltage divider and variable resistor configurations.
For engineers reviewing the X9313WMI-3 datasheet, X9313WMI-3 pinout, X9313WMI-3 application, or X9313WMI-3 equivalent, key selection criteria include its 10kΩ RTOTAL tolerance (±20%), -40°C to +85°C industrial temperature range, MSOP-8 package, 5µs INC-to-VW response time, and nonvolatile recall on power-up.
Technical Context
The X9313WMI-3 implements a 31-element resistor array with make-before-break wiper switching, controlled by a 5-bit up/down counter decoded to select one of 32 tap points. Wiper position is stored in nonvolatile memory only when CS transitions HIGH while INC is HIGH.
Its 3-wire interface uses asynchronous edge-triggered logic: U/D sets direction, negative-edge-triggered INC advances the wiper, and CS enables operation and initiates store. Terminal voltages support ±VCC (–5.5V to +5.5V at VCC = 5.5V), enabling bipolar signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ ±20% - defines full-scale resistance for gain/offset calibration accuracy |
| Wiper taps | 32 linear positions - provides 3.125% resolution per step across full range |
| VCC range | 3V to 5.5V - supports dual-supply systems and 3.3V/5V mixed-signal designs |
| Terminal voltage | –VCC to +VCC - enables use with AC-coupled or bipolar analog signals |
| Wiper resistance | 40Ω typical at VCC = 5V - minimizes loading error in high-impedance feedback paths |
| Power-up behavior | Recalls last stored wiper position - ensures repeatable startup bias without host initialization |
| Endurance | 100,000 data changes per bit - supports field calibration cycles over product lifetime |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), dimensions per JEDEC MO-187-AA, body size 3.0mm × 3.0mm × 1.1mm max.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 3V–5.5V; powers internal logic and resistor array |
| VSS | Ground reference | Return path for supply and signal currents; must be low-impedance |
| RH/VH | High terminal | Fixed end of resistor string; voltage relative to RL/VL depends on U/D state |
| RL/VL | Low terminal | Fixed end of resistor string; forms voltage divider with RH/VH and RW/VW |
| RW/VW | Wiper output | Switched tap point; series resistance ≤100Ω affects precision in low-current applications |
| CS | Chip select | Active-low enable; HIGH initiates nonvolatile store if INC is HIGH |
| U/D | Direction control | Logic level determines wiper increment/decrement on next INC edge |
| INC | Increment clock | Negative-edge triggered; moves wiper one position per valid transition |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains position for 100 years; eliminates need for external EEPROM or host re-initialization |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift - maintains calibration stability across industrial temperature range |
| Make-before-break switching | Prevents open-circuit glitches during wiper movement - critical for closed-loop control stability |
| Bipolar terminal rating | Supports –VCC to +VCC on RH/VH and RL/VL - enables direct use in op-amp inverting stages and AC signal paths |
| Low standby current | 500µA max - reduces quiescent power in battery-operated or always-on sensor front-ends |

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, 10kΩ, 2.7–5.5V supply, 500ppm/°C TC | Requires I²C host; higher resolution but worse tempco; no ±VCC terminal rating | Choose for I²C systems needing finer adjustment; avoid where bipolar signal handling or industrial tempco is required |
| MCP41010-I/P | SPI interface, 257-tap resolution, 10kΩ, 2.7–5.5V, volatile wiper register only | No nonvolatile storage; requires host to reload on power-up; no ±VCC terminal support | Choose for cost-sensitive SPI designs where power-up repeatability is managed externally |
Compared with AD5171BRMZ-10 and MCP41010-I/P, the X9313WMI-3 uniquely combines nonvolatile storage, ±VCC terminal capability, and industrial-grade temperature coefficient in a 3-wire interface-making it optimal for self-contained analog calibration in harsh environments without host processor dependency.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313WMI-3?
The X9313WMI-3 supports |VH – VL| ≤ 10V under recommended operating conditions. This limit applies regardless of VCC level and ensures safe operation of the internal resistor array and wiper switches. Exceeding this differential voltage risks permanent damage to the device's resistive elements.
Does X9313WMI-3 require an external pull-up resistor on the INC line?
No, the X9313WMI-3 does not require an external pull-up on the INC line. Its INC input has CMOS-compatible thresholds (VIL ≤ 0.8V, VIH ≥ 2V) and accepts clean digital edges directly from microcontroller GPIO pins. External pull-ups may cause unintended toggling due to noise or slow rise times.
How is the wiper position stored in nonvolatile memory for X9313WMI-3?
The X9313WMI-3 stores the current wiper position when CS transitions from LOW to HIGH while the INC input is held HIGH. This store operation takes 10ms to complete, after which the device enters standby mode. The stored value is automatically recalled on next power-up, ensuring repeatable startup behavior without host intervention.
Can X9313WMI-3 be used in a bipolar signal path with ±5V supplies?
Yes, the X9313WMI-3 supports terminal voltages from –VCC to +VCC. With VCC = 5V, RH/VH and RL/VL can swing from –5V to +5V, enabling direct integration into ±5V op-amp circuits such as inverting amplifiers or AC-coupled filters without level-shifting circuitry.
What is the typical wiper resistance of X9313WMI-3 and how does it affect circuit performance?
The X9313WMI-3 has a typical wiper resistance of 40Ω at VCC = 5V. In high-gain or high-impedance circuits (e.g., >100kΩ feedback networks), this resistance introduces measurable gain error and temperature-dependent drift. Designers should account for it in precision applications by selecting appropriate RTOTAL values or adding buffer amplifiers.
