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

Microchip LAN9252I/ML is a 64-Pin QFN Ethernet Controller designed for industrial and embedded applications operating at 3.3 V. It supports a maximum data rate of 100 Mbps and provides full duplex and half duplex communication modes. This Ethernet controller is suitable for high-performance network interfacing with low power consumption and compact packaging.

The device features dual integrated Ethernet PHYs, each with an HP Auto-MDI-X capability, enabling use of direct connect or crossover LAN cables without manual intervention. It supports internal loopback mode facilitating diagnostics and maintenance in industrial environments. Packaged in a surface mount QFN (Quad Flat No-lead) with 64 pins, it offers ease of mounting and minimal PCB space usage.

Operating temperature range from -40°C to 85°C ensures reliable performance in harsh industrial conditions. Supported standards include ANSI X3.263, IEEE 802.3u, and IEEE 802.3, making it compliant with established Ethernet protocols.

The LAN9252I/ML integrates a 3-port EtherCAT slave controller with four SyncManagers, three Fieldbus Memory Management Units (FMMUs), and a 64-bit Distributed Clock. It also provides 4K bytes of dual port memory (DPRAM) to facilitate efficient data transfers. The controller interfaces with multiple bus options including SPI/SQI, HBI, and 16-bit digital IO, offering flexible integration with various embedded controllers.

Additional features include cable diagnostic support and 100BASE-FX support through an external fiber transceiver, expanding its networking capabilities. It also includes a 1.8V to 3.3V variable voltage I/O and an integrated 1.2V regulator to support single 3.3V power operation, ensuring power efficiency.
