    10Base-T/100Base-TX Ethernet Controller with 16 bit/MII interface

     

    产品信息

    The LAN9217 is a full-featured, single-chip 10/100 Ethernet controller designed for embedded applications where performance, flexibility, ease of integration and system cost control are required. The LAN9217 has been specifically architected to provide the highest performance possible for any 16-bit application. The LAN9217 is fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant, and supports HP Auto-MDIX.

    The LAN9217 includes an integrated Ethernet MAC and PHY with a high-performance SRAM-like slave interface. The simple, yet highly functional host bus interface provides a glue-less connection to most common 16-bit microprocessors and microcontrollers as well as 32-bit microprocessors with a 16-bit external bus. The LAN9217 includes large transmit and receive data FIFOs to accommodate high latency applications. In addition, the LAN9217 memory buffer architecture allows the most efficient use of memory resources by optimizing packet granularity.

    The  EEPROM device from Microchip comes with a factory programmed, globally unique EUI-48™ MAC Address. This Ethernet controller will automatically detect and load the EUI-48™ node address from the EEPROM at start-up or reset.
