8051 controller with ethernet

[Markus Falkensteiner]

Hi NG,

i'm searching for a microcontroller from the 8051 family (core should be
compatible to 8051core from original Intel)
that has an ethernet controller included. is such kind of microcontroller
available.
and if not, can someone give me a hind which mikrocontroller would be best
for developing ethernetapplication.
i just want to do that for self-study.

PS: also a 16-bit controller would be ok for me, but for the recommended
controller should be developing software-tools available.

thx in advance

try DALLAS or how they are called MAXIM-DALLAS

Check out the Dallas DS80C400, a 75MHz 8051 with ethernet MAC, TCP
stack, CAN2B etc. Although they call it a "microcontroller", its
internal ROM is for the pre-programmed network functions and you'll
have to add external code memory.

A friend of mine has begun working with a 'rabbit'. I have no other
info except that it has TCPIP/ethernet capability

If you don't need high speed but want a way of hooking up a device to a LAN,
I am using these... http://www.lantronix.com/products/eds/xport/index.html
which provide an Ethernet to 3.3v level UART interface. You can also
reprogram the device to do other functions. They are about $35 for one off
quantities. The dev kit is about $110.

I interface from 5V to 3.3V them to PICs using a simple potential divider
(4.7k+8.2k), and for 3.3V to 5V simply wire the pins together: this is
within spec for a PIC (logic 1 is 2V or higher). I use a 3.3V low dropout
regulator to power it (LM3940IT-3.3) with no heatsink required when powered
from 5V.

First time I tried the XPORT, I converted a serial device to an Ethernet
device in under an hour.

(I have no connection with Lantronix other than being a user of their XPORT
product.)
