LAN9252TI/ML

Controllers Overview

The LAN9252TI/ML is a 2/3-port EtherCAT slave controller manufactured by Microchip Technology, housed in a 64-pin QFN (9x9 mm) package. It integrates dual full-duplex 100BASE-TX Ethernet PHYs supporting 100 Mbps operation and HP Auto-MDIX. The device features an EtherCAT slave controller with 4K bytes of Dual Port RAM (DPRAM), three Fieldbus Memory Management Units (FMMUs), and four SyncManagers. Host interfaces include SPI/SQI, HBI, and Digital I/O modes. Operating voltage ranges from 1.8V to 3.3V with an integrated 1.2V regulator for single-supply operation. The industrial temperature range is -40°C to +85°C.

Controllers Procurement Notes

Verify the specific suffix 'TI' corresponds to the industrial temperature grade (-40°C to +85°C) and QFN-64 packaging as documented in the official datasheet. Confirm that the ordering information matches the exact part number required for your design specifications before procurement.

Controllers Selection Notes

Select this component when a robust EtherCAT slave solution with integrated PHYs is required. Ensure the host system supports one of the available interfaces: SPI/SQI, HBI, or Digital I/O. Verify that the application environment falls within the specified industrial temperature range and voltage requirements.

Controllers Part Context

The LAN9252 series serves as a high-performance EtherCAT slave controller designed for industrial automation. The LAN9252TI/ML variant specifically targets industrial environments with its extended temperature rating. It simplifies system design by integrating MAC, PHY, and EtherCAT logic into a single chip, reducing component count and board space compared to discrete solutions.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult Microchip Technology directly for qualified alternatives or cross-reference options compatible with the LAN9252 family.
