Product details
Overview
X9313ZM-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 1kΩ end-to-end resistance. It operates from 3V to 5.5V, supports terminal voltages from –VCC to +VCC, and delivers ±4.4mA wiper current for precision analog trimming in embedded control systems.
For engineers reviewing the X9313ZM-3T1 datasheet, X9313ZM-3T1 pinout, X9313ZM-3T1 application, or X9313ZM-3T1 equivalent, key selection criteria include its 1kΩ RTOTAL tolerance (±20%), 31-resistor array architecture, make-before-break switching, and industrial-grade temperature range (–40°C to +85°C) in an 8-lead MSOP package.
Technical Context
The X9313ZM-3T1 implements a solid-state resistor ladder of 31 elements with electronically switched wiper access at 32 discrete points. Its 5-bit up/down counter drives a decoder that selects one wiper tap per increment/decrement cycle, with store-on-CS↑+INC↑ enabling nonvolatile retention of the last position across power cycles.
Control logic uses negative-edge-triggered INC input, level-sensitive U/D direction control, and active-low CS for device selection and memory write initiation. The wiper terminal (RW/VW) exhibits 40Ω typical series resistance at VCC = 5V, and all terminals support rail-to-rail voltage swing (–VCC to +VCC), enabling bidirectional signal conditioning in both three-terminal potentiometer and two-terminal variable resistor configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 1kΩ ±20% - defines full-scale resistance range for gain/offset calibration accuracy and thermal drift impact. |
| VCC Range | 3V to 5.5V - enables direct compatibility with 3.3V and 5V logic systems without level-shifting. |
| Wiper Current | ±4.4mA max - sets maximum allowable load current before nonlinear wiper resistance dominates output behavior. |
| Resolution | 3% - corresponds to 1/31 step size (≈32.3Ω per tap at 1kΩ), determining minimum adjustable voltage division granularity. |
| Endurance | 100,000 data changes per bit - guarantees long-term reliability in field-adjustable calibration loops. |
| Data Retention | 100 years - ensures factory-set or user-trimmed values persist over product lifetime without battery backup. |
| Temp Range | –40°C to +85°C - qualifies for industrial ambient operation without derating or external compensation. |
| Package | 8-lead MSOP (M8.118) - 3.0mm × 3.0mm footprint with 0.65mm pitch, suitable for space-constrained PCB layouts. |
Pinout & Package
Package: 8-lead MSOP (Mo-187-AA compliant, M8.118 drawing), 3.0mm × 3.0mm body, 0.65mm lead pitch, Pb-free matte tin termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 3V–5.5V; powers internal logic, memory, and resistor array; must be stable before CS/INC activation. |
| VSS | Ground reference | Common return for all signals and resistor array; requires low-impedance connection to minimize noise coupling. |
| 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; forms complete resistive path with RH/VH; supports bidirectional voltage swing. |
| RW/VW | Wiper output | Movable tap point; 40Ω typical series resistance at 5V; connects to analog signal path requiring precise voltage division. |
| CS | Chip select | Active-low enable; stores wiper position when transitioned HIGH while INC is HIGH; places device in standby when HIGH and INC LOW. |
| U/D | Direction control | Level-sensitive input; determines whether INC edge increments (U/D = HIGH) or decrements (U/D = LOW) wiper position. |
| INC | Increment clock | Negative-edge-triggered; each falling edge moves wiper one tap; timing requires tIL ≥ 1µs and tIH ≥ 1µs per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last position across power cycles without external EEPROM or battery; eliminates startup recalibration. |
| Make-before-break switching | Prevents open-circuit transients during wiper movement; avoids signal dropout in critical feedback paths. |
| Rail-to-rail terminal voltage support | Allows VH and VL to swing from –VCC to +VCC; enables bipolar signal conditioning in op-amp interfaces. |
| Temperature-compensated resistor array | ±300 ppm/°C RTOTAL drift and ±20 ppm/°C ratiometric tracking ensure stable voltage division over temperature. |
| Low-power CMOS operation | 3mA max active current and 500µA max standby current reduce system-level power budget impact. |
| Industrial-grade reliability | 100-year data retention and 100,000-cycle endurance validated per JEDEC standards for long-life deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5170BRMZ-10 | I²C interface, 256 taps, 10kΩ RTOTAL, 2.7–5.5V supply; no native nonvolatile store-requires external EEPROM or MCU-initiated restore. | Better resolution (0.4% vs 3%) but lacks automatic power-up recall; suited for high-precision, MCU-managed trimming. | Select when higher tap count and I²C integration outweigh need for autonomous power-up behavior. |
| MCP41HV51-103 | 10kΩ RTOTAL, SPI interface, 256 taps, 4.5–20V operation; volatile wiper register only-no nonvolatile memory. | Supports higher voltage rails (up to 20V) but requires continuous MCU supervision; unsuitable for unattended recalibration. | Choose for high-voltage analog front-ends where 3-wire simplicity and nonvolatility are secondary to voltage range. |
Compared with AD5170BRMZ-10 and MCP41HV51-103, the X9313ZM-3T1 uniquely combines 3-wire simplicity, true autonomous power-up recall, and 1kΩ low-R value ideal for current-sensing and low-impedance feedback paths-without demanding additional MCU firmware or external memory.

FAQ
What is the maximum voltage that can be applied across RH/VH and RL/VL terminals of the X9313ZM-3T1?
The X9313ZM-3T1 supports terminal voltages from –VCC to +VCC, and its absolute maximum ∆V = |VH – VL| is specified as 4V for the Z-series (1kΩ variant). This limit ensures safe operation of the internal resistor array and switching elements without degradation or latch-up, even when VCC = 3V or 5.5V.
Does the X9313ZM-3T1 require external pull-up or pull-down resistors on its control pins?
No, the X9313ZM-3T1 does not require external biasing on CS, U/D, or INC inputs. Its input leakage current is ±10µA max, and VIH/VIL thresholds (2.0V/0.8V at VCC = 5V) are compatible with standard CMOS logic outputs. Internal design ensures reliable operation with direct GPIO or microcontroller drive.
How is wiper position stored and recalled in the X9313ZM-3T1?
Wiper position is stored in nonvolatile memory when CS transitions HIGH while INC is held HIGH; the stored value is automatically loaded to the wiper counter on power-up. This recall occurs within 10µs after VCC stabilizes, ensuring deterministic startup behavior without MCU intervention for X9313ZM-3T1.
Can the X9313ZM-3T1 be used in a two-terminal variable resistor configuration?
Yes, the X9313ZM-3T1 supports two-terminal operation by connecting either RH/VH or RL/VL to the wiper (RW/VW) and using the remaining fixed terminal with the other side of the circuit. This configuration provides digitally adjustable resistance from 0Ω to RTOTAL (1kΩ), with wiper resistance (40Ω typ.) contributing minimally at mid-scale.
What is the significance of the "-3" suffix in X9313ZM-3T1?
The "-3" suffix in X9313ZM-3T1 denotes extended VCC operating range (3V to 5.5V), distinguishing it from the standard 5V-only variants (e.g., X9313ZM). This allows direct use with 3.3V systems and mixed-voltage designs without level translation, while maintaining full functionality including nonvolatile store and rail-to-rail terminal voltage capability.
