Product details
Overview
X9313WM from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 10 kΩ end-to-end resistance, 3-wire serial interface (CS/U/D/INC), ±VCC terminal voltage capability, and nonvolatile wiper position storage. It functions as a solid-state replacement for mechanical potentiometers in precision analog trimming applications such as DC bias adjustment in op-amp circuits.
For engineers reviewing the X9313WM datasheet, X9313WM pinout, X9313WM application, or X9313WM equivalent, key selection criteria include its 10 kΩ RTOTAL value, MSOP-8 package, 0°C to +70°C operating range, 3-wire control protocol, and nonvolatile recall on power-up - all critical for embedded analog calibration systems requiring repeatable settings without external memory.
Technical Context
The X9313WM 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 position stored in nonvolatile EEPROM upon CS↑ while INC = HIGH.
Control logic operates at VCC = 3V to 5.5V, supporting both 3V and 5V systems. Terminal voltage tolerance spans –VCC to +VCC, allowing bipolar signal routing; wiper resistance is 40 Ω (typ.) at VCC = 5V, and absolute linearity is ±1 MI (minimum increment = RTOTAL/31).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10 kΩ ±20% - defines full-scale resistance for voltage divider or current-limiting use; stable across temperature (±300 ppm/°C) |
| Wiper Positions | 32 linear taps - enables 3.125% resolution per step (1/31 increment); supports precise analog gain/bias tuning |
| VCC Range | 3V to 5.5V - compatible with modern low-voltage microcontrollers and legacy 5V systems without level shifting |
| Terminal Voltage Range | –VCC to +VCC - permits direct connection to bipolar op-amp rails (e.g., ±5V, ±12V) without external clamping |
| Nonvolatile Storage | 100-year data retention, 100,000 write cycles - eliminates need for battery-backed RAM or external EEPROM in field-deployed equipment |
| Power Consumption | 3 mA active max, 500 µA standby - suitable for always-on industrial sensors and low-power portable instrumentation |
| Package | 8-lead MSOP (M8.118), RoHS-compliant - compact footprint (3.0 × 3.0 mm) with thermal pad compatibility for high-reliability PCB layouts |
Pinout & Package
Package: 8-lead MSOP (Mo-187-AA compliant), body size 3.0 mm × 3.0 mm × 1.1 mm, exposed pad optional, Pb-free matte tin terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply rail | Accepts 3V–5.5V; powers internal logic, memory, and resistor array; must be stabilized before CS activation |
| VSS | Ground reference | Common return for all digital inputs and analog terminals; requires low-impedance connection to minimize noise coupling |
| RH/VH | High terminal | Fixed end of resistor string; voltage polarity relative to wiper depends on U/D direction, not absolute potential |
| RL/VL | Low terminal | Fixed opposite end of resistor string; forms complete potentiometer path with RH/VH and RW/VW |
| RW/VW | Wiper output | Movable tap point; series resistance ≤100 Ω ensures minimal loading in voltage-divider configurations |
| CS | Chip select | Active-low enable; stores wiper position when transitioned HIGH while INC = HIGH; places device in standby when HIGH |
| U/D | Direction control | Logic level sets wiper movement direction (HIGH = increment, LOW = decrement); can be changed dynamically during CS = LOW |
| INC | Increment clock | Negative-edge-triggered; advances wiper one position per valid edge; timing min. pulse width = 1 µs (tIL/tIH) |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, vibration sensitivity, and contact noise - ideal for automotive and industrial environments |
| 3-wire serial interface | Requires only three GPIOs (CS/U/D/INC) - simplifies integration with resource-constrained MCUs lacking SPI peripherals |
| Nonvolatile wiper recall | Restores last-trimmed setting at power-on - enables factory calibration lock and eliminates manual re-adjustment in field units |
| Temperature-compensated array | ±300 ppm/°C end-to-end drift - maintains ratio accuracy across 0°C to +70°C operating range without software compensation |
| Bipolar terminal rating | Supports –VCC to +VCC voltages - enables direct use in dual-supply op-amp feedback networks and AC-coupled signal paths |
| Make-before-break switching | Prevents open-circuit glitches during wiper transitions - critical for stable bias in amplifier gain-setting and sensor offset circuits |
Applications
| Audio Signal Level Control | DC Bias Adjustment in Op-Amp Circuits |

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 RTOTAL, ±20% tolerance, same MSOP-8 package | Requires I²C master; higher resolution but no native 3-wire support; lacks ±VCC terminal rating (max ±5V) | Choose for systems already using I²C infrastructure and needing finer adjustment granularity |
| MCP41010-I/P | SPIM interface, 257-tap resolution, 10 kΩ RTOTAL, ±20% tolerance, PDIP-8 package (not MSOP) | Higher resolution and faster update rate (2 MHz SPI), but through-hole only; no nonvolatile recall on power-up (requires external command) | Choose for prototyping on breadboards or legacy through-hole designs where SPI is available and EEPROM recall is managed externally |
Compared with AD5171BRMZ-10 and MCP41010-I/P, the X9313WM offers unique 3-wire simplicity, true bipolar terminal operation, and guaranteed nonvolatile recall - making it optimal for cost-sensitive, space-constrained, and dual-supply analog trimming where minimal GPIO count and autonomous power-up behavior are mandatory.

FAQ
What is the maximum allowable voltage across RH and RL terminals for the X9313WM?
The X9313WM supports a maximum differential voltage |VH – VL| of 10 V, as specified in the Absolute Maximum Ratings table for X9313W-series devices. This rating applies regardless of VCC level and enables safe operation in ±5 V and ±12 V dual-supply systems when used within the –VCC to +VCC terminal voltage range. Exceeding 10 V risks permanent damage to the internal resistor array.
Does the X9313WM require an external pull-up resistor on the INC pin?
No, the X9313WM does not require an external pull-up on the INC pin. Its INC input has CMOS-compatible thresholds (VIL ≤ 0.8 V, VIH ≥ 2 V) and leakage current limited to ±10 µA, allowing direct connection to an MCU GPIO configured as push-pull output. Internal circuitry ensures reliable negative-edge detection without external biasing.
Can the X9313WM be used in a two-terminal variable resistor configuration?
Yes, the X9313WM can operate as a two-terminal variable resistor by connecting either RH/VH or RL/VL to RW/VW and using the remaining fixed terminal with the wiper. This configuration is explicitly supported in the datasheet and commonly used for current-limiting or gain-setting applications where only one adjustable resistance node is needed.
How long does it take for the X9313WM wiper to stabilize after a power-up event?
The X9313WM wiper stabilizes within 10 µs after VCC reaches its final value, as specified by tPU (power-up to wiper stable) in the AC Electrical Specifications. This rapid settling occurs automatically upon nonvolatile recall and requires no host intervention, ensuring immediate analog functionality in time-critical systems like real-time sensor interfaces.
Is the X9313WM RoHS-compliant and lead-free?
Yes, the X9313WM is RoHS-compliant and lead-free. Per the Ordering Information table, the "Z" suffix denotes Pb-free packaging, and the device uses 100% matte tin plate (e3 termination finish) compatible with both SnPb and Pb-free soldering processes, including wave and reflow (except for PDIP variants).
