    Hello Sir,
    I want to interface Ethernet controller with microcontroller. I see some Ethernet controller in which SPI interface there. I have doubt, Is there different microcontroller have different Ethernet controller. Currently I have 89s52 microcontroller.
    Can you suggest me which Ethernet controller is useful for me ?..

    Thanking you...

    With Regards,

    An 8051 class machine is unlikely to have a reasonable choice for an ethernet controller. Since a maximum length packet can be over 1500 bytes long buffer space can be problematical. The lack of effective DMA capability is also an impediment. If it is possible at all then I would look into chips by Realtek and SMS (Scientific Micro Systems). I'm not hopeful you will find success.

    On the other hand an AVR32UC3A0512 comes with ethernet and USB support on board. At the price of an 8-bit AVR it is a hard bargain to pass up.
