Product details
Overview
X9313WSIZT1 from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 3-wire serial interface (CS/U/D/INC), nonvolatile wiper position storage, and 10 kΩ end-to-end resistance. It operates from 4.5 V to 5.5 V, supports ±VCC terminal voltages, and functions as either a three-terminal potentiometer or two-terminal variable resistor in analog trimming applications.
For engineers reviewing the X9313WSIZT1 datasheet, X9313WSIZT1 pinout, X9313WSIZT1 application, or X9313WSIZT1 equivalent, key selection criteria include its 10 kΩ RTOTAL, industrial temperature range (–40°C to +85°C), SOIC-8 package, nonvolatile recall on power-up, and compatibility with digital control systems requiring stable analog adjustment without mechanical wear.
Technical Context
The X9313WSIZT1 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 = 5 V.
Control logic responds to negative-edge-triggered INC input under active CS (LOW), with U/D determining direction. A HIGH-to-LOW CS transition while INC is HIGH initiates nonvolatile store; stored position is automatically recalled at power-up, ensuring repeatable startup behavior without host intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10 kΩ - defines full-scale resistance for voltage divider or current-limiting configurations |
| Wiper taps | 32 positions - enables 3.125% resolution per step across full resistance range |
| VCC range | 4.5 V to 5.5 V - compatible with standard 5 V logic and supply rails |
| Temperature range | –40°C to +85°C - qualified for industrial environments without derating |
| Terminal voltage range | –VCC to +VCC - supports bipolar signal handling (e.g., ±5 V analog paths) |
| Wiper resistance | 40 Ω typical at VCC = 5 V - minimizes insertion error in precision divider applications |

Pinout & Package
Package: 8-lead SOIC (Pb-free, RoHS compliant), footprint per JEDEC MS-012-AA, body width 3.9 mm, lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply voltage input | Provides power for internal logic 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 |
| 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 of resistor array; forms complete resistive path with RH/VH and RW/VW |
| RW/VW | Wiper terminal | Output node connected to selected tap; series resistance ≤100 Ω ensures minimal loading in feedback networks |
| CS | Chip select | Active-low enable; HIGH during store operation (with INC HIGH) triggers nonvolatile write |
| U/D | Direction control | Defines increment/decrement direction for wiper movement; may change dynamically during CS LOW |
| INC | Increment clock | Negative-edge-triggered; each valid edge moves wiper one position; timing tCYC ≥2 µs required |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, contact bounce, and vibration sensitivity inherent in electro-mechanical potentiometers |
| Nonvolatile wiper storage | Retains last-set position across power cycles, enabling deterministic startup without host reinitialization |
| Make-before-break switching | Prevents open-circuit transients during wiper movement, critical for stability in op-amp feedback loops |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift and ±20 ppm/°C ratiometric coefficient ensure consistent divider ratio over temperature |
| 3-wire serial interface | Requires only three GPIO lines (CS/U/D/INC), reducing MCU pin count versus I²C or SPI alternatives |
| Pb-free SOIC-8 package | RoHS-compliant, JEDEC-standard footprint compatible with automated SMT assembly and reflow profiles |

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, 2.7–5.5 V supply | Higher resolution and dual-channel capability but requires I²C bus resources and lacks ±VCC terminal rating | Select when multi-channel trimming or finer adjustment granularity is needed and I²C infrastructure exists |
| MCP41010-I/P | SPIM interface, single 10 kΩ channel, 257-tap resolution, 2.7–5.5 V supply, volatile wiper register | Higher resolution and SPI compatibility but no nonvolatile storage-requires host to reload position on power-up | Select when SPI is preferred and system firmware can manage wiper initialization; avoid where power-loss recovery is critical |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313WSIZT1 offers guaranteed power-up repeatability without host interaction, robust ±VCC analog terminal tolerance for bipolar signal paths, and minimal GPIO overhead-making it optimal for industrial trimming where reliability and simplicity outweigh resolution demands.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313WSIZT1?
The X9313WSIZT1 supports ΔV = |VH – VL| up to 10 V, as specified for X9313W-series devices. This allows use in ±5 V analog signal paths without risk of exceeding terminal voltage limits. Exceeding this differential voltage may cause irreversible damage to the internal resistor array or switches.
Does X9313WSIZT1 retain its wiper position after power cycling?
Yes, X9313WSIZT1 stores the wiper position in nonvolatile memory upon command (CS HIGH with INC HIGH) and automatically recalls it at power-up. This ensures repeatable startup behavior without host MCU involvement, supporting unattended operation in remote or embedded systems.
Can X9313WSIZT1 be used with a 3.3 V microcontroller interface?
No-X9313WSIZT1 is rated for VCC = 4.5 V to 5.5 V and requires CMOS-compatible logic levels referenced to that supply. Driving CS, U/D, or INC from a 3.3 V MCU without level translation risks unreliable operation or failure to meet VIH/VIL thresholds; a dedicated 5 V supply or level shifter is required.
What is the wiper resistance specification for X9313WSIZT1 and why does it matter?
X9313WSIZT1 has a typical wiper resistance of 40 Ω at VCC = 5 V (max 100 Ω). This low value minimizes insertion error in precision voltage divider configurations-especially critical in op-amp feedback networks where added series resistance degrades gain accuracy and stability.
Is X9313WSIZT1 compatible with reflow soldering processes?
Yes, X9313WSIZT1 is supplied in Pb-free SOIC-8 packaging qualified for standard lead-free reflow profiles per IPC/JEDEC J-STD-020. The device meets MSL Level 1 requirements and does not require moisture-sensitive handling-enabling direct placement into high-volume SMT assembly lines.
