Product details
Overview
X9313ZPZ-3 from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 1kΩ 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 functions as a three-terminal voltage divider or two-terminal variable resistor in precision analog trimming applications.
For engineers reviewing the X9313ZPZ-3 datasheet, X9313ZPZ-3 pinout, X9313ZPZ-3 application, or X9313ZPZ-3 equivalent, key selection criteria include its 1kΩ RTOTAL tolerance (±20%), wiper resistance (40Ω typ. at 5V), 100k-cycle endurance, 100-year data retention, and compatibility with industrial temperature range (–40°C to +85°C) in SOIC-8 packaging.
Technical Context
The X9313ZPZ-3 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 while CS is low.
Wiper position is stored in nonvolatile memory when CS rises while INC is high, ensuring automatic recall at power-up. Terminal voltage range spans –VCC to +VCC, supporting bipolar signal conditioning, and the device draws ≤3mA active current and ≤500µA standby current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 1kΩ ±20% - defines full-scale resistance for gain/offset calibration circuits |
| Wiper Resolution | 32 taps (31 segments) - provides ~3% step resolution for fine analog adjustment |
| VCC Range | 3V to 5.5V - supports dual-supply systems and legacy 3.3V/5V mixed-rail designs |
| Terminal Voltage Range | –VCC to +VCC - enables use in AC-coupled or bipolar op-amp feedback networks |
| Wiper Resistance | 40Ω typical at VCC = 5V - minimizes loading error in high-impedance voltage divider configurations |
| Endurance | 100,000 data changes per bit - ensures long-term reliability in field-adjustable calibration systems |
| Data Retention | 100 years - guarantees factory-set or user-trimmed values persist across product lifetime |
Pinout & Package
Package: 8-lead SOIC (Pb-free, RoHS compliant), 3.9mm × 4.9mm body, 1.27mm lead pitch, M8.15 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Power source for internal logic and resistor array; must be applied before control signals during power-up |
| VSS | Ground reference | Return path for supply and signal currents; forms common reference for RH/VH, RL/VL, and VW |
| 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 opposite end of resistor array; used with RH/VH to define total resistance path |
| RW/VW | Wiper output | Movable tap point; delivers divided voltage or variable resistance; series resistance ≈40Ω affects accuracy in low-R load conditions |
| CS | Chip select | Active-low enable; stores wiper position on rising edge when INC is high; places device in standby when high and inactive |
| U/D | Direction control | Logic level sets increment/decrement direction of wiper movement; may be changed dynamically during CS low |
| INC | Increment clock | Negative-edge-triggered step command; toggling moves wiper one position; timing critical (tCYC ≥2µs) |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, contact bounce, and vibration sensitivity-ideal for embedded recalibration loops |
| Nonvolatile wiper storage | Retains last-set position across power cycles without external EEPROM or backup power |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift and ±20 ppm/°C ratiometric stability preserve gain accuracy over industrial temperature range |
| Make-before-break switching | Prevents open-circuit glitches during wiper transitions-critical for stable feedback in closed-loop amplifiers |
| Bipolar terminal voltage support | Accepts –VCC to +VCC at RH/VH and RL/VL-enables direct integration into ±5V or ±3.3V signal chains |

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, 10kΩ RTOTAL, 256-tap resolution, no nonvolatile storage | Requires external EEPROM or MCU firmware to retain settings; higher resolution but less robust for unattended recalibration | Choose when I²C bus availability and finer adjustment granularity outweigh need for autonomous power-up recall |
| MCP41010-I/P | SPI interface, 10kΩ RTOTAL, volatile wiper register, 128-tap resolution | No inherent power-on default; relies on host MCU to reinitialize wiper at startup | Prefer when SPI is already used in system and calibration is always performed under host control |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313ZPZ-3 uniquely combines nonvolatile storage, bipolar terminal voltage support, and 1kΩ low-RTOTAL in a 3-wire interface-making it optimal for self-contained, recalibratable analog front-ends where MCU intervention is minimal or unavailable.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313ZPZ-3?
The X9313ZPZ-3 specifies ΔV = |VH − VL| ≤ 4V for the X9313Z variant. This limit ensures safe operation of the internal resistor array and switching network. Exceeding 4V risks irreversible damage to the 1kΩ element structure, even if individual terminal voltages remain within –VCC to +VCC bounds. Always verify voltage differential in circuit simulation or bench testing before deployment.
Does X9313ZPZ-3 require an external pull-up resistor on the INC line?
No, the X9313ZPZ-3 does not require an external pull-up on the INC line. Its INC input has CMOS-compatible thresholds (VIL ≤ 0.8V, VIH ≥ 2V) and ≤10µA leakage, allowing direct connection to microcontroller GPIO pins configured as push-pull outputs. Internal design ensures reliable negative-edge detection without external biasing-reducing BOM count and layout complexity.
Can X9313ZPZ-3 be used in a bipolar ±5V op-amp circuit?
Yes, the X9313ZPZ-3 supports terminal voltages from –VCC to +VCC. With VCC = 5V, RH/VH and RL/VL accept –5V to +5V, enabling direct use in ±5V op-amp feedback networks. However, ensure VW remains within –5V to +5V and that wiper current stays within ±4.4mA limits. The 1kΩ RTOTAL and 40Ω wiper resistance maintain accuracy in such configurations without additional level-shifting circuitry.
How is wiper position stored and recalled in X9313ZPZ-3?
Wiper position is stored in nonvolatile memory when CS transitions HIGH while INC is held HIGH. Upon subsequent power-up, the stored value is automatically loaded into the wiper counter, positioning RW/VW at the last saved tap. This occurs within 10µs after VCC stabilizes, requiring no host initialization. The X9313ZPZ-3 retains this value for 100 years, making it ideal for factory-trimmed or field-calibrated systems.
Is X9313ZPZ-3 pin-compatible with other X9313 variants in SOIC-8 package?
Yes, all X9313 variants-including X9313ZPZ-3, X9313WSZ-3, and X9313USZ-3-share identical SOIC-8 pinout (M8.15 outline), pin functions, and electrical interface. Differences lie only in RTOTAL (1kΩ vs. 10kΩ vs. 50kΩ), temperature grade (–40°C to +85°C), and VCC range (3V–5.5V). This allows drop-in substitution when resistance value and operating range align with design requirements.
