Hi,i am dong a project with a lpc2368 and DP83848 for ethernet
communication.
i want to do the layout with two layer PCBA,but NXP application note
recommend do it with at least four layer, if anyone done the similar
project with two layer PCB? please comment it, thanks in advance

Hi, could you please let me know what is the price about such device?
I've just finish to develop a Ethernet interface by using the EM200
Tibbo module
around a existent application with a LPC2106. I've just 1 week to
develop it and I've no more choiche other
than use a embedded module such this one. Now I've some time and I'd
like to develop a low cost
interface then the reason for my request.

Thanks in advance

Regards

Fabio Filippa

DP83848 just a ethernet PHY transceiver chip, and LPC2368 has a MAC
controller inside it.
i think EM200 is a module ethernet to RS232 convertor. no on-board
design. right?
you can check the price in www.digikey.com or national website, i
just got several samples by free.

EM200 has Wiznet IC W5100 (or so). These devices are Ethernet with built in
TCP/IP stack, and talk to micro by SPI port.
We are regularly using these. W5100 and 8052 make an excellent web server
with CGI scripts. With ARM + MMC probably you can make one of the best
embedded server.

Dear Steven,
EM200 is a embedded solution, MAC and PHY are inside the module you have
just to add the external magnetics to get all working.
Also the module is able to manage by yourself the ICMP (ECHO command)
and severla other protocol.
>From external system point of view you can access the module trough a
configurable serial port then simply attach the serial port to our
microcontroller serial port.

yes, i got it. thanks
but i still decide to use national's PHY transceiver and lpc2368(MAC
on-chip) for our design. thanks any way

Dear Deshmukh,
thanks for the info about the W5100 chip.
I've taked a look at the datasheet and seems very good.
At now I've added Ethernet feature to a old design based on LPC2106 by
using the TIBBO module,
I've no more time to make the upgrade with low cost solution and in a 1
wk all is done, but with this W5100
chip I can do more cost saving than simply use the TIBBO module.
Well could you please let me know a little bit about the chip usage? I
think I've to add some code to my LPC2106
in oder to manage the info exchange with the W5100, to do this I can
work with interrupt to signal our micro that some has to be processed,
>From a first lecture I don't have to take care about TCP/IP stack
because this should be implemented inside the W5100 with
also some various protocol (TCP, UDP, ICMP, IPv4 ARP, IGMP, PPPoE,
Ethernet) then I've just to wait for incoming data
and read it from the ASIC isn't it?
Also I need to add the magnetics before the Ethernet plug.

Thanks in advance
Fabio Filippa

Yes, its very simple, cheap (w5100+magjack cost around $10), you have 100
Mb Ethernet connection, and a simple PCB design.
On the flip side, the Tx/Rx buffers are small (2-8Kb), and fragmented
packets are not supported.

You need SPI, INT, and reset lines from micro, in software you have to
initialize few registers, and then open a socket (TCP / UDP) and listen,
and reply. You also have option of raw sockets.
