NCN26000XMNTBG

Controllers Overview

The NCN26000XMNTBG is a 10BASE-T1S Ethernet transceiver compliant with IEEE 802.3cg, designed for industrial multi-drop networks. It operates at a data rate of 10 Mb/s in half-duplex mode over a single unshielded twisted pair. The device connects to MAC controllers via a standard MII interface and supports Physical Layer Collision Avoidance (PLCA) for collision-free operation on shared media. It functions on a 3.3 V supply voltage ranging from 2.97 V to 3.63 V. Operating temperatures range from -40 °C to +125 °C. The component is housed in a 5 mm x 5 mm QFN-32 package.

Controllers Feature Summary

• Supports Physical Layer Collision Avoidance (PLCA) for multi-drop segments
• Integrates Enhanced Noise Immunity Mode for high-noise environments
• Provides bootstrap configuration via dedicated strap pins during boot
• Features an Isolated Mode where interface pins remain high impedance until enabled

Controllers Applications

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

Controllers Procurement Notes

Verify the ordering suffix against the manufacturer's current documentation to confirm specific package variants or tape-and-reel specifications. Ensure that the required operating temperature range and supply voltage tolerances align with the target system design constraints before finalizing procurement.

Controllers Selection Notes

Select this component when designing systems requiring IEEE 802.3cg compliance for single-pair Ethernet. It is suitable for applications needing PLCA-based arbitration on shared media. Verify that the host MAC controller supports the standard MII interface and can manage Clause 22 and Clause 45 MDIO registers for proper configuration.

Controllers Part Context

This part belongs to the NCN26000 series of industrial Ethernet PHYs. It is specifically engineered for 10BASE-T1S applications, distinguishing itself from standard copper PHYs by supporting multi-drop topologies. The series integrates the PLCA reconciliation sublayer directly into the silicon to simplify network architecture.

Controllers Replacement Considerations

Check for other NCN26000 variants with different suffixes if alternative packaging or boot configurations are required. No direct cross-brand substitutes are documented in the official datasheet.
