Full-featured single-chip 10/100 industrial Ethernet controller and PHY

Now available from Mouser stock, Microchip's LAN9250 10/100 industrial Ethernet controller and PHY is a full-featured, single-chip solution for embedded applications. The LAN9250 provides performance, flexibility, ease of integration and system cost control. It has been specifically designed to provide high performance and throughput for 16-bit applications. The LAN9250 complies with IEEE 802.3 (full/half-duplex 10BASE-T and 100BASE-TX) Ethernet protocols, IEEE 802.3az Energy Efficient Ethernet (EEE) (100Mbps only), and the IEEE 1588v2 precision time protocol. 100BASE-FX is supported via an external fibre transceiver. The LAN9250 includes an integrated Ethernet MAC and PHY with a high-performance SRAM-like slave interface. The integrated checksum offload engines enable the automatic generation of the 16-bit checksum for received and transmitted Ethernet frames, offloading the task from the CPU. The LAN9250 also includes large transmit and receive data FIFOs to accommodate high latency applications. In addition, the LAN9250 memory buffer architecture allows highly efficient use of memory resources by optimizing packet granularity. Applications include cable, satellite, and IP set-top boxes, digital televisions / video recorders, VoIP/Video phone systems, home gateways, test / measurement equipment, and industrial automation systems.
