PIC to ethernet - is it possible?
zalzon - 01:02 26-07-04
Hi,
My research into my embedded webserver project is going in
circles. I need to find some way to connect the PIC to an ethernet
controller before I attempt to write a working TCP/IP stack.
I have a 32bit 5volt PCI ethernet card. Is it possible to connect the
PIC chip to just a few o...
Microcontroller with integrated ethernet?
Mike V. - 20:10 04-03-04
Hi, I was wondering on anyone's experiences with the new low end (i.e.
8 bit) microcontrollers with integrated ethernet.
All I can think of are the following:
1. eZ80 Acclaim from Zilog.
2. DS80C400 (an 8051 core) with integrated ethernet.

Hello there,
I wonder whether somebody provide non-PCI gigabit Ethernet controller.
I mean a Ethernet transceiver with PHY and MAC that can interface a
DSP, or a microcontroller to Ethernet communication.
It seems most gigabit Ethernet controller are communicating to PCI bus.
