Hi, I recently posted asking about ethernet on eZ80 microprocessor. Is there a better processor to use? I spoke with an engineer at Zilog, and it appears that working with the MAC layer directly is going to be extremely difficult. Are there any microcontrollers that are better suited for this task? I need to run it in promiscuous mode, which is also a problem with the eZ80 because it can actually only support upto 4 Mbps, and I most likely need upto 10. Any suggestions of boards with easy access to the MAC layer, high data rates, and just good boards would be highly appreciated. Thanks. -Greg

AMCC is now responsible for this line now but the part is fast, has a built in MAC which you could set to receive all frames, and can use cheap PC133 SDRAM chips or SRAM if you don't need much memory. -- - Mark -> --

Take a look at our dev boards....www.netburner.com If you are looking for a CPU, try the Motorola Coldfire parts at the low end of the product line 10/100 MAC and 32 bit processor can be had for < $9.00 Paul On 21 May 2004 12:19:41 -0700, gkuperman@yahoo.com (Greg) wrote:>Hi, I recently posted asking about ethernet on eZ80 microprocessor.

They have what you are looking for, in many flavors. Look around, you'll find boards, perhaps even reasonably priced.

Thanks. >-GregThere are plenty of ARMs with integrated Ethernet controllers, and the Samsung S3C4510B is one we have used. This chip is used in many of the cheap four port routers. It can be had for less than US$7.50 in volume. As for boards, contact me by email (remove XXX and INVALID.) and I'll see if our client can supply you.

We got the dev board from WBC (???) in the UK, so I expect they have proto quantities as well.
