Product details
Overview
X9313WM-3 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), nonvolatile wiper position storage, and ±VCC terminal voltage capability. It operates from 3V to 5.5V and is used for precision analog trimming in power supply feedback loops, sensor calibration circuits, and programmable gain amplifiers.
For engineers reviewing the X9313WM-3 datasheet, X9313WM-3 pinout, X9313WM-3 application, or X9313WM-3 equivalent, key selection criteria include its 10 kΩ RTOTAL tolerance (±20%), wiper resistance (40 Ω typ. at 5V), 100,000-cycle endurance, 100-year data retention, and MSOP-8 package compatibility with industrial temperature range (0°C to +70°C).
Technical Context
The X9313WM-3 implements a 31-element resistor array with electronically switched wiper taps controlled by an up/down counter and decoded via 5-bit logic. Its "make-before-break" switching ensures continuity during wiper transitions, while nonvolatile memory stores the last position for automatic recall at power-up.
Control relies on three dedicated digital inputs: CS (active-low device select), U/D (direction control), and INC (negative-edge-triggered increment/decrement). A store operation occurs only when CS rises while INC is high, placing the device into standby mode afterward.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10 kΩ ±20% - defines full-scale resistance range for voltage divider or variable resistor use |
| Wiper Resolution | 32 taps (31 segments) - enables 3.125% step resolution across full resistance range |
| VCC Range | 3V to 5.5V - supports dual-supply systems and low-voltage embedded designs |
| Terminal Voltage Range | −VCC to +VCC - allows bipolar signal handling without external level-shifting |
| Wiper Resistance | 40 Ω typical at VCC = 5V - minimizes insertion error in precision analog paths |
| Endurance | 100,000 data changes per bit - ensures long-term reliability in field-adjustable systems |
| Data Retention | 100 years - maintains calibrated settings across product lifetime without battery backup |
Pinout & Package
The X9313WM-3 is housed in an 8-lead MSOP package (JEDEC MO-187-AA compliant, 3.0 mm × 3.0 mm body, 0.65 mm pitch), RoHS-compliant with matte tin (e3) termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Power source for internal logic and resistor array; must be applied before signal voltages |
| VSS | Ground reference | Common return path for all internal circuitry and external connections |
| RH/VH | High terminal | Fixed end of resistor array; voltage polarity relative to wiper depends on U/D state |
| RL/VL | Low terminal | Fixed end of resistor array; complements RH/VH in three-terminal configuration |
| RW/VW | Wiper output | Movable tap point; series resistance ≤100 Ω ensures minimal loading in feedback networks |
| CS | Chip select | Active-low enable; rising edge with INC = HIGH triggers nonvolatile store operation |
| U/D | Direction control | Logic level sets wiper movement direction (up/down) during INC transitions |
| INC | Increment clock | Negative-edge-triggered; toggles wiper position one tap per valid edge |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Eliminates need for external EEPROM or MCU supervision to retain trim settings after power loss |
| 3-wire serial interface | Reduces GPIO count vs. I²C/SPI; compatible with simple microcontroller GPIOs without protocol overhead |
| ±VCC terminal voltage range | Enables direct connection to op-amp rails or AC-coupled signals without clamping diodes or biasing networks |
| Make-before-break switching | Prevents open-circuit glitches during wiper transitions-critical in closed-loop control applications |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift ensures stable gain/offset over 0°C to +70°C operating range |

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 10 kΩ channel, 256-tap resolution, 10 ppm/°C tempco | Requires I²C master; higher resolution but no nonvolatile store per channel | Select for multi-channel systems needing synchronous adjustment and tighter tempco |
| MCP41010-I/P | SPITM interface, single 10 kΩ channel, 257-tap resolution, volatile wiper register only | No nonvolatile memory; requires external MCU to reload setting at startup | Select when SPI is preferred and system firmware manages persistent storage |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313WM-3 offers simpler 3-wire control, guaranteed nonvolatile retention without host intervention, and bipolar terminal voltage support-making it optimal for standalone analog trimming where reliability and ease of integration outweigh resolution or multi-channel needs.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313WM-3?
The X9313WM-3 supports ΔV = |VH − VL| up to 10 V, as specified for the "W" series variant in the Absolute Maximum Ratings table. This limit applies regardless of VCC level and ensures safe operation of the internal resistor array and switching elements without degradation or latch-up.
Does X9313WM-3 require an external pull-up resistor on the INC line?
No, the X9313WM-3 does not require an external pull-up on the INC line. Its digital inputs (CS, U/D, INC) have CMOS-compatible thresholds and leakage current ≤±10 µA, allowing direct connection to microcontroller GPIOs configured as push-pull outputs. Internal design ensures reliable edge detection without external biasing.
Can X9313WM-3 be used in a bipolar signal path with ±5V rails?
Yes, the X9313WM-3 supports terminal voltages from −VCC to +VCC. With VCC = 5V, RH/VH and RL/VL can swing from −5V to +5V, enabling direct use in bipolar op-amp circuits, AC-coupled filters, and differential sensor interfaces without level-shifting components.
How is the wiper position stored in nonvolatile memory on X9313WM-3?
The X9313WM-3 stores the current wiper position when CS transitions from LOW to HIGH while INC is held HIGH. This store command takes 10 ms to complete, after which the device enters standby mode. The stored value is automatically recalled within 10 µs of power-up, ensuring deterministic startup behavior.
What is the typical wiper resistance of X9313WM-3 and how does it affect accuracy?
The X9313WM-3 has a typical wiper resistance of 40 Ω at VCC = 5V (max 100 Ω). In voltage divider configurations, this adds series resistance between the wiper and load, introducing gain error-especially critical in high-impedance feedback paths. Designers should verify error budgets using worst-case RW in their specific circuit topology.
