Product details
Overview
X9313WS-3T1 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 ±VCC terminal voltage capability. It functions as a solid-state replacement for mechanical potentiometers in precision analog trimming, bias adjustment, and programmable gain control circuits operating from 3V to 5.5V supply.
For engineers reviewing the X9313WS-3T1 datasheet, X9313WS-3T1 pinout, X9313WS-3T1 application, or X9313WS-3T1 equivalent, key selection criteria include its 10kΩ end-to-end resistance, industrial temperature range (–40°C to +85°C), SOIC-8 package, 3-wire interface timing compliance, and nonvolatile recall behavior on power-up.
Technical Context
The X9313WS-3T1 implements a 31-element resistor array with electronically switched wiper access at 32 discrete taps. Wiper position is controlled by an up/down counter decoded to select one of thirty-two analog output points, with make-before-break switching during transitions.
Its nonvolatile memory stores the last wiper setting via CS↑ while INC is HIGH, enabling automatic restoration on subsequent power cycles. The device operates in active mode (≤3mA) when CS is LOW and enters standby (≤500µA) when deselected, supporting low-power system-level trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 10kΩ ±20% - defines full-scale analog range and current-handling capability in voltage divider or variable resistor configurations |
| Wiper resolution | 32 taps - provides 3.125% step resolution across total resistance, enabling fine-grained analog parameter control |
| Supply voltage range | 3V to 5.5V - supports dual-rail compatibility with 3.3V and 5V logic systems without level-shifting |
| Terminal voltage range | –VCC to +VCC - allows bidirectional signal handling (e.g., ±5V rails) without external clamping diodes |
| Nonvolatile store time | 10ms - ensures reliable wiper position retention after CS↑/INC↑ event, critical for deterministic power-up behavior |
| Wiper resistance | 40Ω typical at VCC = 5V - minimizes insertion error in precision voltage divider applications |
| Operating temperature | –40°C to +85°C - validated for industrial-grade embedded systems requiring thermal stability |
Pinout & Package
Package: 8-lead SOIC (Pb-free, RoHS compliant), 3.9mm × 4.9mm body, 1.27mm pitch, JEDEC MS-012-AA compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Power source for internal logic and resistor array; must be stable before applying control signals |
| VSS | Ground reference | Common return path for supply, logic, and analog terminals; requires low-impedance PCB connection |
| RH/VH | High terminal | Fixed end of resistor array; voltage polarity relative to wiper depends on U/D direction, not absolute potential |
| RL/VL | Low terminal | Fixed opposite end of resistor array; forms complete resistive path with RH/VH and RW/VW |
| RW/VW | Wiper terminal | Movable contact point; delivers analog output proportional to stored tap position; series resistance ≤100Ω |
| CS | Chip select | Active-low enable; initiates wiper movement when LOW; triggers nonvolatile store on rising edge if INC is HIGH |
| U/D | Direction control | Logic level determines whether INC toggles wiper up (HIGH) or down (LOW); state may change dynamically during CS LOW |
| INC | Increment clock | Negative-edge triggered; each falling edge moves wiper one tap in U/D-defined direction; timing min. 2µs cycle |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last position for ≥100 years; eliminates need for external EEPROM or MCU initialization code on boot |
| 3-wire serial interface | Requires only CS, U/D, and INC lines - reduces GPIO count vs. SPI/I²C, simplifies microcontroller integration |
| Make-before-break switching | Prevents open-circuit transients during wiper movement; avoids signal dropout in sensitive analog paths |
| Temperature-compensated array | ±300 ppm/°C end-to-end drift - maintains ratio accuracy across industrial temperature range |
| ±VCC terminal rating | Supports rail-to-rail analog signals up to ±5.5V - enables direct use in bipolar op-amp feedback networks |

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, 10kΩ RTOTAL, 2.7–5.5V supply | Requires I²C host; higher resolution but no native nonvolatile store on power-up (requires external command) | Choose for systems with I²C infrastructure and need for finer adjustment granularity |
| MCP41010-I/P | SPITM interface, 257-tap resolution, 10kΩ RTOTAL, 2.7–5.5V supply, volatile wiper register | No nonvolatile memory; wiper resets to mid-scale on power-up unless MCU reinitializes | Choose when high-resolution trimming is prioritized over autonomous power-up behavior |
Compared with AD5171BRMZ-10 and MCP41010-I/P, the X9313WS-3T1 offers deterministic power-up behavior without host intervention, minimal GPIO usage (3-wire), and proven industrial temperature reliability-making it optimal for maintenance-free analog calibration in embedded systems.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313WS-3T1?
The X9313WS-3T1 supports a maximum differential voltage of 10V between RH/VH and RL/VL terminals, as specified for X9313W-series devices. This rating applies across the full –40°C to +85°C operating range and enables use in ±5V analog signal paths without external protection circuitry.
Does X9313WS-3T1 retain its wiper position after power removal?
Yes, X9313WS-3T1 stores the wiper position in nonvolatile memory with guaranteed data retention for 100 years. Upon power-up, the device automatically recalls the last stored position, eliminating the need for MCU initialization or external memory writes during system boot.
Can X9313WS-3T1 operate from a 3.3V supply?
Yes, X9313WS-3T1 is rated for 3V to 5.5V operation, making it fully compatible with standard 3.3V logic systems. Its 3-wire interface inputs (CS, U/D, INC) meet TTL/CMOS thresholds across this supply range, and active current remains ≤3mA at 3.3V.
What is the wiper resistance specification for X9313WS-3T1?
The wiper resistance for X9313WS-3T1 is 40Ω typical at VCC = 5V, with a maximum of 100Ω. This low on-resistance minimizes gain error in precision voltage divider configurations and ensures predictable loading effects in feedback networks.
