Product details
Overview
X9313WMZ-3T1 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 supply and functions as a solid-state replacement for mechanical potentiometers in precision analog trimming applications.
For engineers reviewing the X9313WMZ-3T1 datasheet, X9313WMZ-3T1 pinout, X9313WMZ-3T1 application, or X9313WMZ-3T1 equivalent, key selection criteria include its 10 kΩ RTOTAL, MSOP-8 package, -40°C to +85°C industrial temperature range, 3-wire control timing, and nonvolatile recall behavior on power-up - all critical for embedded analog calibration systems requiring repeatable settings across power cycles.
Technical Context
The X9313WMZ-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 wiper resistance typically 40 Ω at VCC = 5V and terminal voltage tolerance of ±VCC.
Nonvolatile memory stores wiper position upon CS↑ while INC = HIGH, retaining data for 100 years with 100,000 write cycles. The device supports both three-terminal potentiometer and two-terminal variable resistor configurations, with absolute linearity ±1 MI and ratiometric temperature coefficient ±20 ppm/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10 kΩ ±20% - defines full-scale resistance range for voltage divider or current-limiting use |
| Wiper Positions | 32 linear taps - enables 3.125% resolution per step (1/31 increment) |
| VCC Range | 3V to 5.5V - supports dual-supply systems and battery-powered 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 gain-setting circuits |
| Nonvolatile Retention | 100 years - ensures factory-trimmed calibration remains valid over product lifetime |
| Endurance | 100,000 data changes per bit - supports frequent field recalibration in test equipment |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), dimensions per JEDEC MO-187-AA, body size 3.0 mm × 3.0 mm × 0.85 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Power rail for internal logic and resistor array; must be stable before CS activation |
| VSS | Ground reference | Common return for all digital and analog paths; decoupling required near pin |
| CS | Chip select input | Active-low enable; rising edge with INC = HIGH triggers nonvolatile store |
| U/D | Direction control input | Defines wiper movement direction (up/down) during INC toggling; may change dynamically |
| INC | Increment clock input | Negative-edge triggered; each pulse moves wiper one position in U/D-defined direction |
| RH/VH | High terminal | Fixed end of resistor array; voltage rating extends to ±VCC relative to VSS |
| RL/VL | Low terminal | Fixed end opposite RH/VH; polarity defined by U/D direction, not voltage potential |
| RW/VW | Wiper output | Movable tap point; series resistance ≤100 Ω ensures minimal loading in feedback networks |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Eliminates need for external EEPROM or MCU backup; restores last setting automatically at power-on |
| 3-wire serial interface | Reduces GPIO count vs. I²C/SPI; compatible with simple microcontroller GPIOs without protocol overhead |
| ±VCC terminal voltage range | Enables direct use in op-amp gain-setting, offset adjustment, and bipolar signal conditioning without level shifters |
| Make-before-break wiper switching | Prevents open-circuit glitches during tap transitions - critical for stable closed-loop control |
| Temperature-compensated resistor array | ±20 ppm/°C ratiometric TC ensures consistent voltage division across industrial temperature 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 |
|---|---|---|---|
| AD5171BRMZ-10 | I²C interface, 64-tap resolution, 10 kΩ RTOTAL, 2.7–5.5V supply | Requires I²C master; higher resolution but no native 3-wire support | Select when system already uses I²C and needs finer adjustment granularity |
| MCP41010-I/P | SPITM interface, 257-tap resolution, 10 kΩ RTOTAL, 2.7–5.5V supply, volatile wiper | No nonvolatile storage; requires external MCU to reload setting on power-up | Select when cost sensitivity outweighs need for autonomous power-on restore |
Compared with AD5171BRMZ-10 and MCP41010-I/P, the X9313WMZ-3T1 uniquely combines 3-wire simplicity, nonvolatile recall, and ±VCC terminal tolerance - making it optimal for space-constrained industrial calibrators where GPIO count, power-cycle robustness, and bipolar signal compatibility are decisive.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313WMZ-3T1?
The X9313WMZ-3T1 supports ΔV = |VH − VL| up to 10 V, as specified for X9313W variants in the Absolute Maximum Ratings table. This limit applies regardless of VCC level and ensures safe operation within the 10 kΩ resistor array's power rating of 10 mW.
Does X9313WMZ-3T1 retain its wiper position after power removal?
Yes, X9313WMZ-3T1 stores the wiper position in nonvolatile memory upon a CS↑ transition while INC = HIGH. That value is automatically recalled within 10 µs of VCC stabilization during subsequent power-up, ensuring repeatable analog settings without host intervention.
Can X9313WMZ-3T1 be used with a 3.3V microcontroller GPIO driving CS, U/D, and INC?
Yes, X9313WMZ-3T1 supports VCC from 3V to 5.5V and specifies VIH = 2.0 V and VIL = 0.8 V for control inputs. A 3.3V MCU meets these thresholds directly, enabling reliable interfacing without level translation.
What is the wiper resistance specification for X9313WMZ-3T1 at 3.3V supply?
The datasheet specifies RW = 40 Ω typical at VCC = 5V. While not explicitly tested at 3.3V, the wiper resistance is dominated by MOSFET on-resistance and remains ≤100 Ω across the full 3V–5.5V VCC range, as confirmed by the "Wiper Resistance" parameter limit in the Potentiometer Characteristics table.
Is X9313WMZ-3T1 RoHS compliant and lead-free?
Yes, X9313WMZ-3T1 is Pb-free and RoHS compliant, using 100% matte tin (e3) termination finish and packaging materials qualified for both SnPb and Pb-free soldering processes per IPC/JEDEC J-STD-020.
