Microchip 64-Pin QFN Ethernet Controller 3.3 V 100 Mbps Host Bus Full Duplex/Half Duplex LAN9252I/ML

Microchip LAN9252I/ML is a high-performance 64-Pin QFN Ethernet controller designed for robust industrial communication applications. Operating at a supply voltage of 3.3 V, it supports a maximum data rate of 100 Mbps over host bus interface and allows full duplex and half duplex communication modes.

This device integrates a 2/3-port EtherCAT slave controller with dual Ethernet PHYs featuring HP Auto MDI-X capability, enabling flexible cable connection options. The internal architecture includes 4K bytes of Dual Port RAM, 4 SyncManagers, and 3 Fieldbus Memory Management Units (FMMUs), facilitating efficient real-time data exchange over EtherCAT networks.

The LAN9252I/ML supports multiple process data interfaces including SPI, SQI, Host Bus Interface, and 16-bit Digital IO, allowing compatibility with a wide range of 8-bit, 16-bit, and 32-bit embedded controllers. The integrated 1.2V voltage regulator simplifies board design with single 3.3V power supply operation.

With an operating temperature range from -40°C to 85°C, this Ethernet controller is well suited for industrial, automation, and manufacturing environments requiring reliable communication links. Its compact 9mm x 9mm footprint and 1mm height make it ideal for space-constrained surface mount PCB assemblies.

Supports 2/3-port EtherCAT slave controller architecture with multiple memory management units. Dual integrated Ethernet PHYs with HP Auto-MDI-X cable diagnostics. Compatible with multiple embedded controller interfaces including SPI and HBI.

Internal 1.2V regulator for simplified power management. Wide operating temperature ensures industrial durability. Compact 64-pin QFN package for surface mount technology. Supports 100BASE-FX via external fiber optic transceiver.
