Microchip Ethernet controllers

[Philip]

For anyone interested in the Microchip ENC28J60 standalone ethernet controller and the new PIC micros that will have built in ethernet capability.

[Philip]

here is another PPT document with and overview of the standalone and the micros with ethernet. I have the data sheet for the standalone but it is too big to post, sorry :-(.

Has anyone been able to acquire Microchip's new ENC28J60 Ethernet Controller? There have been many press releases over the last few months and Microcontroller.com states:

"Limited sampling for the ENC28J60 Ethernet controller is available now, and volume production is expected in May. Options include 28-pin SPDIP, SOIC, SSOP and QFN packages. For additional information, contact any Microchip sales representative or authorized worldwide distributor, or visit Microchip’s Web site."

It doesn't seem that we can order or sample these online yet. Still working out the bugs...?

At this time it's still listed as a future product.

When it appears at www.buymicrochip.com then it's available.

I am checking the status of the ENC28J60 Ethernet Controller. What is on their website is not always current. If I find out more I will post here.

[Philip]

Current status (not withstanding Microchip changing their mind or having errata) the device is sampling mid july and full production end of july. This from my Microchip rep.

Cheers,
Philip

I found a pretty cool board from EDTP Electronics that will be sold as soon as Microchip releases the ENC28J60. This board includes all of the necessary passive and magnetic components in order to add ethernet to a microcontroller project.

Has anyone tried these yet?
Pity I'm out of microchip sample orders till next month.

Hi,

Ok, the last info of the master 2005:

Silicon Errata ECN28J60 B1 Silicon
=============================
TO: Worldwide Distributor/Rep Partners
DT: August 15th, 2005
RE: Silicon Errata for the ENC28J60

Dear Valued Distribution Partner,

This memo is to inform you of the latest updates and silicon errata regarding the ENC28J60 Ethernet controller. Revision B1 is currently undergoing
engineering evaluation including characterization and qualification testing internal to Microchip. This revision is expected to release to production
very soon.

One important point to note is that the original expectation was that an industrial temperature range could be achieved. However, after extensive
testing, it became evident that a more conservative temperature rating of 0 to 70C was required to meet the required yield levels. (See Errata item
number 3.) All existing orders for industrial temperature devices will
automatically be changed to the commercial temperature equivalent beginning
August 22nd, unless we hear otherwise from you between now and then.

I have more documents, and will post this later.

We still testing a few samples / applications of the ENC28J60/SO and the software will by writing in ... yes ...PBP. When finish I will post some here.

Beste regards,

I spoke to Microchip in Calif today and also to Arrow, a main distributor. The word today is the chip won't be out until the end of the year so maybe samples will be available in January sometime. Even though the wait seems to never end on this one, at about $5 it will be a real deal!

The Microchip ENC28J60 is now available for purchase and sampling! I just received mine last week. Can't wait to get an Ethernet project going...

[IanLowe]

Samples arrived this morning!

Now to see if we can make this baby fly :D

The datasheet is a bit of a beast, so hopefully everything should be in there to get a sample app working. I see as well that Fred at EDTP has a couple of circuits up already.

nice.

I.

Fred Eady has published C code for ENC28J60 drivers. See Eady-191.zip at...

I just received one the other day and WoW it works. A little power hungry but it did take some time to debug the C to PICBasic routines.

Any chance you'll be that "resource for others" and share the conversion?

Can we start a section both in schematics and PicBasicPro in the forum to deal with the ENC28J60 chip?

I've read through the monster datasheet from microchip and am wondering if we can start discussion on various (many) details regarding using this chip with PICBASIC.


As I understand it the microcontroller will communicate via SPI with the ENC28J60, is it possible for us to develop PICBASIC commands to help setup and initialize the ENC chip and also send and receive data?

Maybe we can call them NICOUT and NICIN?

anyone else getting started with these that might want to work together?

[toddc]

Hi. I'd like to learn about Ethernet applications. I'm a rank-beginner to PICs, but would like to participate in the discussion. :)

[RYTECH]

This is a great tutorial for using Bascom-AVR code to drive the ENC28J60

http://members.home.nl/bzijlstra/software/examples/enc28j60.htm

Anyone have similar PICBASIC code?

[RYTECH]

I'm a beginner / noob so please excuse me ahead of time for being a goof.

I found this work done by Gabi MIHAILA ... it seem's to contain a good start to working in PICBASIC with the ENC28J60...

http://download.collem.nl/enc28j60.zip

The include file (the driver?) looks especially good as it seems to include everything to at least get us to an initialized setup.

I'm expecting to receive my ENC28J60's shortly.. i've also ordered some MAGJACK RJ45 jacks (they have integrated magnetics) and am hoping to have the initial circuit on my breadboard soon as I'm eager to get more farmiliarized with network capable microcontroller applications.

The main areas right now (before I've really done anything - but after a fair amount of reading) of concern are:

A) Clock source (PIC has seperate crystal? PIC is Clock from ENC28J60? how does this all effect SPI etc.)

B) 3.3v levels of the ENC28J60 and 5v PIC... Can I run at 3.3v all around or should i expect to be implementing some kind of level shifting? (not to many sources describe the particulars in this area.)

C) Debugging interface

Is there a more appropriate area to be posting all this?

[dhouston]

Have you seen the ongoing threads about programming the PIC18F67J60 (in essence a PIC married to the ENC28J60) in the PicBasicPro forum?

http://www.picbasic.co.uk/forum/showthread.php?t=7000&highlight=PIC18F67J60

[RYTECH]

I have reveiwed that thread but when I looked up that part microchip didn't seem to offer a DIP version so I stuck to trying to get going with the ENC28J60.

[dhouston]

My point was that you might find the PBP code for the 18F67J60 is transferable to the ENC28J60. I haven't really looked at it in depth but Fred has C code for both and has ported the 18F67J60 C code to PBP.

BTW, for anyone finding it hard to source the Magjack Fred used with both the Frame Thrower and Ethernet Mini, the Pulse JP011821U (Mouser 673-JP011821U) is equivalent.

[RYTECH]

Thanks for posting the other link, i'll check it out the other thread again. After solving early problems I had with the USB 18F4550 chip (breadboard,doh!) by moving my setup to a (very crappily built) PCB (under exposed-developed / over soldered). If the code for the "All in one" requires much modification I might have trouble - I'm not the most capable programmer (yet).

I'm sure I'll post any updates to keep other's informed... which is when i'll zap you with all my brainless self answering questions.
