Overview

Description

The LAN9252I/ML is a highly integrated 2/3-port Ethernet controller from Microchip, designed for industrial Ethernet applications. It supports 10/100 Mbps Ethernet and features an integrated dual-port switch, making it ideal for real-time communication in automation and motion control systems.
Key features include:
- SPI or parallel host interface for flexible microcontroller connectivity.
- Hardware-based IEEE 1588 Precision Time Protocol (PTP) for accurate synchronization.
- Industrial temperature range (-40°C to +85°C) for harsh environments.
- Integrated PHYs, reducing external component count.
It is commonly used in EtherCAT, PROFINET, and EtherNet/IP applications, offering low-latency communication and deterministic performance. The LAN9252I/ML simplifies design while ensuring robust, high-speed industrial networking.

Equivalent

The LAN9252I/ML is a 2/3-port EtherCAT slave controller. Equivalent or similar products include:
- Microchip LAN9253 (3-port variant)
- Beckhoff ET1100/ET1200 (EtherCAT slave controllers)
- Renesas RZ/N2L (EtherCAT-enabled MCUs)
- Texas Instruments AMIC110 (Sitara processor with EtherCAT support)
These alternatives offer comparable EtherCAT functionality, though pin compatibility and features may vary. Always check datasheets for exact replacements.

Package

The LAN9252I/ML is available in a 48-pin QFN (Quad Flat No-Lead) package. This compact, surface-mount package measures 7x7mm with a 0.5mm pitch, making it suitable for space-constrained designs. The QFN package offers good thermal performance and electrical characteristics, ideal for Ethernet controller applications.
