Hi,
I'm currently working on a project using the enc424j600.

So I've done the board, initialized enc424j600, the LEDs are showing link status properly, and I can read the state of the link with the mcu (no TCP/IP stack yet), but the chip gets pretty hot. Is it normal?

I checked and double-checked all connections and everything seems to be fine.

P.S. I'm using AMPHENOL - RJMG163118101NR as jack + magnetics.

Thank you very much!

Thank you very much for you answer Jorge. Unfortunately I have two more :) I´m currently in my project´s specification phase. I´m thinking on trying PIC24FJ64GA004 interfacing with ENC424J600. This is a 16Mips MCU. I noticed that you have chosen a 40 MIPS micro for your purpose. Since I haven´t tried TCP/IP stack yet, I would really appreciate if you can tell me if I could suffer from severe performance penalty using this 16MIPS MCU.
Another design issue is web page external storage in a serial flash SPI memory. I wonder if I can share the SPI bus with ENC624J600 or my second SPI interface (wich will be listening to a MRF24J40MA module). That´s because my app. will be using all available MCU I/Os including the 2d SPI hw interface. I think this memory will be accesed JUST ONCE from web browser, but I want to make sure because my app. would probably be quite compute-intensive.
It can be very difficult to cope with too many read accesses to this memory from the web browser.
I was thinking also in using a 1Mbit I2C eeprom as an alternative although its lower data-rate.
Thank you vey much in advance. Regards.

Hi Fede,
yes the Microchip TCP/IP Stack supports the ENC424J600 and ENC624J600 using SPI and various parallel modes.
You can find the stack as part of the Microchip Application Library at http://www.microchip.com/mal
Cheers

Hello, I´m involved in a similar project. I wonder if Microchip TCP/IP stack does include drivers for the ENC24J600. Does it?
Thnak you very much.

Thanks Jorge :) good to know for the future..
