NCN26010XMNTXG

Controllers Overview

The NCN26010XMNTXG is a 10BASE-T1S compliant Ethernet transceiver integrating a Media Access Controller (MAC), PLCA Reconciliation Sublayer, and physical layer. It operates on a single 3.3 V supply with a recommended range of 2.97 V to 3.63 V. The device supports a data rate of 10 Mb/s over a single unshielded twisted pair cable. Communication with host microcontrollers occurs via an Open Alliance compatible SPI interface with a maximum clock frequency of 25 MHz. It functions within an ambient temperature range of -40 °C to +125 °C and utilizes a 4 mm x 4 mm QFN-32 package.

Controllers Feature Summary

• Integrates MAC, PLCA RS, and 10BASE-T1S PHY for industrial multi-drop networks
• Supports Physical Layer Collision Avoidance (PLCA) for collision-free operation on shared media
• Features Enhanced Noise Immunity Mode for communication in high-noise environments
• Includes configurable digital outputs capable of driving low current LEDs

Controllers Applications

• Industrial Automation
• Sensor Interfacing
• Home and Building Control
• Security and Field Instrumentation

Controllers Procurement Notes

Verify the component against official datasheet specifications before integration. Confirm that the QFN-32 package dimensions and pinout match the design requirements. Ensure the host system provides the necessary 3.3 V power supply and SPI interface timing constraints. Check for any specific ordering suffixes or environmental certifications required by the application standards.

Controllers Selection Notes

Select this component for applications requiring IEEE 802.3cg compliance on a single twisted pair. It is suitable for systems needing integrated MAC and PHY functionality without external controllers. Consider the thermal characteristics and operating temperature range when designing the PCB layout. Verify that the host MCU supports the required SPI protocol and voltage levels for reliable communication.

Controllers Part Context

This part belongs to the NCN26010 series of industrial Ethernet transceivers from onsemi. It is designed specifically for multi-drop segments using a single unshielded twisted pair. The series includes variants with different packaging options, such as TQFP-32, while maintaining identical electrical and functional specifications across the family.

Controllers Replacement Considerations

Direct replacements must maintain IEEE 802.3cg compliance and similar pin configurations. Evaluate alternative packages like TQFP-32 if form factor changes are acceptable. Ensure substitute components support PLCA and have comparable noise immunity features for industrial environments.
