Product details
Overview
X9313WMZT1 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), and nonvolatile wiper position storage. It operates from 4.5 V to 5.5 V, supports ±VCC terminal voltages, and is used for precision analog trimming in voltage divider and variable resistor configurations.
For engineers reviewing the X9313WMZT1 datasheet, X9313WMZT1 pinout, X9313WMZT1 application, or X9313WMZT1 equivalent, key selection criteria include its 10 kΩ RTOTAL tolerance (±20%), wiper resistance (40 Ω typ. at 5 V), 100,000-cycle endurance, 100-year data retention, and MSOP-8 package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The X9313WMZT1 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 U/D and step triggered by negative-edge INC.
Wiper position is stored in nonvolatile memory when CS rises while INC is HIGH, and automatically recalled at power-up. Terminal voltage range spans –VCC to +VCC, supporting bipolar signal conditioning, 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 division or current limiting; impacts gain accuracy in amplifier feedback networks. |
| Terminal Voltage Range | –VCC to +VCC - enables operation with bipolar analog signals up to ±5.5 V, suitable for AC-coupled or dual-supply systems. |
| Wiper Resistance | 40 Ω typical at VCC = 5 V - contributes minimal series error in low-impedance paths; critical for precision reference adjustment. |
| Endurance | 100,000 data changes per bit - ensures long-term reliability in field-adjustable calibration loops without wear-out failure. |
| Data Retention | 100 years - guarantees factory-set or user-trimmed values persist across product lifetime without battery backup. |
| Supply Current | 3 mA max active, 500 µA max standby - supports low-power embedded systems with intermittent trim requirements. |
| Resolution | 3% - corresponds to 32-tap granularity; determines smallest adjustable step in gain, offset, or threshold settings. |
Pinout & Package
Package: 8-lead MSOP (Moisture Sensitivity Level 1, RoHS-compliant, Pb-free matte tin finish, JEDEC MO-187-AA compliant; dimensions: 3.0 mm × 3.0 mm × 0.95 mm height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Must be applied before analog terminals; powers internal logic and resistor array; ramp rate limited to 0.2–50 V/ms. |
| VSS | Ground reference | Common return for digital control and analog terminals; required for proper wiper decoding and memory operation. |
| CS | Chip select enable | Active-low; initiates control mode; rising edge with INC HIGH triggers nonvolatile store; high state enables standby mode. |
| U/D | Wiper direction control | Logic level sets increment/decrement direction; may change dynamically during CS LOW without interrupting operation. |
| INC | Wiper step trigger | Negative-edge sensitive; toggling moves wiper one tap; timing requires tIL ≥ 1 µs and tCYC ≥ 2 µs. |
| 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 end opposite RH/VH; forms complete resistive path with RH/VH; supports two-terminal variable resistor use. |
| RW/VW | Wiper output | Movable contact point; delivers tapped voltage or resistance; series resistance ≤100 Ω ensures minimal loading error. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, vibration sensitivity, and contact noise-enables reliable operation in automotive and industrial environments. |
| Nonvolatile wiper storage | Recalls last-trimmed position at power-up without external EEPROM or MCU intervention-reduces BOM and firmware overhead. |
| Temperature-compensated array | ±300 ppm/°C end-to-end TC and ±20 ppm/°C ratiometric TC ensure stable gain/offset over –40°C to +85°C industrial range. |
| Make-before-break switching | Prevents open-circuit glitches during wiper movement-critical for maintaining closed-loop stability in active filter or regulator feedback paths. |
| 3-wire serial interface | Requires only three GPIOs (CS/U/D/INC); no clock or data lines needed-simplifies integration into resource-constrained microcontrollers. |
Applications
| Audio Signal Level Control | DC Power Supply Trim |

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 | 2-channel I²C interface, 10 kΩ, 256 taps, 0.1% RAB tolerance, but no nonvolatile storage. | Requires external MCU to retain settings; better resolution but higher complexity for single-trim applications. | Select when multi-channel coordination or finer resolution outweighs need for autonomous power-up recall. |
| MCP41010-I/P | Single-channel SPI interface, 10 kΩ, 256 taps, volatile wiper register, no EEPROM; needs external reset/init code. | Lower cost and faster update rate, but loses setting on power loss-unsuitable for unattended recalibration. | Select for cost-sensitive, MCU-managed trimming where firmware guarantees initialization at boot. |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313WMZT1 trades tap count and interface flexibility for autonomous operation-its nonvolatile memory eliminates dependency on host processor state, making it optimal for standalone analog subsystems requiring guaranteed repeatability after cold start.

FAQ
What is the operating voltage range for the X9313WMZT1?
The X9313WMZT1 operates from 4.5 V to 5.5 V on VCC. Its analog terminals (RH/VH, RL/VL, RW/VW) tolerate voltages from –VCC to +VCC, allowing ±5.5 V signal handling. This range is fixed per the WMZ ordering code and does not support 3 V operation-use X9313WMZ-3 variants for 3 V to 5.5 V compatibility.
Does the X9313WMZT1 retain its wiper position after power cycling?
Yes, the X9313WMZT1 stores the wiper position in nonvolatile memory and automatically recalls it at power-up. This behavior occurs without external intervention because the device reads memory during the 10 µs power-up stabilization period (tPU) and sets RW/VW accordingly. The stored value persists for 100 years under normal conditions.
How many wiper positions does the X9313WMZT1 support, and what is the resolution?
The X9313WMZT1 provides 32 discrete wiper positions across its 10 kΩ resistor array, corresponding to 31 equal resistive elements. Resolution is 3%, calculated as 100% ÷ 32. Each step represents one minimum increment (MI = RTOTAL/31 ≈ 322.6 Ω), with absolute linearity error bounded to ±1 MI and relative linearity to ±0.2 MI.
Can the X9313WMZT1 be used as a two-terminal variable resistor?
Yes, the X9313WMZT1 can operate as a two-terminal variable resistor by connecting either RH/VH or RL/VL to RW/VW and using the remaining terminal with ground or signal source. In this mode, resistance varies from near 0 Ω (wiper at shorted terminal) to RTOTAL (wiper at open terminal), maintaining the same 32-step control and nonvolatile storage capability as in three-terminal mode.
What package type and footprint does the X9313WMZT1 use?
The X9313WMZT1 uses an 8-lead MSOP package (JEDEC MO-187-AA compliant, pkg drawing M8.118), measuring 3.0 mm × 3.0 mm × 0.95 mm. It features gull-wing leads, 0.65 mm pitch, and RoHS-compliant matte tin plating. The footprint requires 0.25 mm lead width and 2.20 mm × 0.60 mm pad dimensions per manufacturer-recommended land pattern.
