ethernet controller microcontroller
Hi to all
I need to build a Hardware which could receive 1 MByte/s from a ethernet line and then process it. I want to select a suitable microcontroller with built in ethernrt controller.
Searching products of Maxim,Motorola, Atmel, ... I have found several devices. Now I want to select one of them and begin my design. The important parameters are:
speed: Fast ethernet (100 Base)
ease of use: simple programmer, availabe libraries,...
ease of PCB design: 2-layer, and not to require special requirments in PCB design
and cost.
If you are experienced with such products please give me your guidelines to choose the best product.
thanks.

microcontroller with eternet connection
if u r interested in mcu without having built in ethernet controller, u can connect microchip's pic to RTL8019AS ethernet controller ( also available in old isa nic's )
there is a rich library written in c complier for that, at

microcontroller with inbuilt ethernet controller
Dear ful babu
Thank you for your help and attention.
It is'nt very important for me to use a micro with Built in LAN controller or a micro plus a stand alone LAN controller chip. I have already some options such as connecting an Atmel's Atmega128 micro to a SMSC's LAN91c111 LAN controller or using micros with built in LAN controller such as Freescale's MC9S12NE64 or Maxim's DS80C400. my question is about comparrision between different choises and the parameteres as I have mentioned are speed, cost, ease of use, ease of PCB design and ease of programming. I 'm afraid if your advised device, RTL8019AS, which is a 10 Base LAN controller, could manage such speed about 1MByte/s(=8Mbit/s) because of network stack overhead. I think I have a point to 100 Base LAN in my question.
thanks

microcontroller with inbuilt ethernet
1Mbyte/sec is quite high speed for any 8-bit controller. First of all, you are right that you need at least a 100baseT LAN. You will have to find a suitable MAC. Unless the controller is only streaming data sequentially from RAM, you need quite a powerfull controller, maybe a 32-bit controller.

sorry mr. layaghi i cant compare atmel zilog and others caz i only work with MICROCHIP and RENESAS, but i think i hav somthing in which u might be interested in, RENESAS SH-ETHER family, hav a look

best 9s12ne64 rabbit
Try Rabbit semi. They have high speed CPU boards and also ethernet boards to go with these. YOu can also try controllers from Z-world. They also have these.

An alternate would be to try embedded PCs. They are full fledge PCs for industrial environment. Search for PC104 and embedded PC. You will find many links.

Hi glenjoy
What is the maximum rate the eZ80 can transmit data via the eternet connection?
Thanks

Re: microcontroller with ethernet controller
Dear cdcll
The maximum Throughput of the 9S12NE64 is 10Mbit/s which hasn' t enough margin
needed for my project that needs about 8Mbit/s Throughput.
thanks

Re: microcontroller with ethernet controller
Sorry. I'm interested in the Microchip's TCP/IP stack but yet to look at it...

You might want to check it out yourself:

Re: microcontroller with ethernet controller
Dear hill
Thank you for your kind help.
But I find this sentence:" The software is ideal for applications that do not require high data throughput over the Internet connection such as in alarm systems, air conditioning systems, home appliances and vending machines" in this link of the microchip site:
http://ww1.microchip.com/downloads/en/Market_Communication/031102a.doc
I need a throughput of about 8Mbit/s. Do you still recamand the "Microchip's TCP/IP stack together with its micro-controller"? if so please give more explanations.
thank you very much

microcontroller with ethernet controller
I have not used the rabbit myslef. But I guess it can give the performance of 1Mb/s if used right. It also depends on what you intend to transmit on top of ethernet. For example, TCP/IP is quite a heavy protocol for 8-bit controllers. Bit if you want to use your own protocol on top of ethernet, you may want to keep it simple to speed up the transfer.

Ethernet controller
(EtherC)
• MAC (Media Access Control) functions
 Data frame assembly/disassembly (IEEE802.3-compliant frames)
 CSMA/CD link management (collision avoidance, processing in case
of collision)
 CRC processing
 Built-in FIFOs (512 bytes each for transmission and reception)
 Supports full-duplex transmission/reception
 Transmitting and receiving short and long packets
• Compatible with MII (Media Independent Interface) standard
 Converts 8-bit stream data from MAC level to MII nibble stream (4 bits)
 Station management (STA) functions
 18 TTL-level signals
 Variable transfer rate: 10/100 Mbps
• Magic Packet™* (with WOL (Wake On LAN) output)

Re: microcontroller with ethernet controller
Dear ful babu
Thank you for your attention
I want to know the maximum throughput of your suggested chips not the 10 or 100 LAN.
excuse me if my question wasn't so clear.

Dear techie as I said I need 8Mbit/s = 1 Mbyte/s throughput. And I find this sentence from RCM3200 FAQ:
"The current maximum transmit end-to-end throughput with TCP is roughly 4 Mbits on the 44MHz RCM3200. Receiving with TCP is about 3 Mbits/sec.

With UDP you have the opportunity to go faster. Transmits using either UDP without checksums or using the low level packet driver pd_sendpacket routine run over 10Mbits/second. With checksums that number drops to 7.8Mbits because of the extra work processing the data." form this link:
http://69.93.17.252/support/bb/messages/14/4894.html?1039545174

And you know there is a need for some margins also.
However thank you very much.

Yes it can transmit data of course.
You can use a "Magnetics" between the Rj45 connector and ethernet controller.
magnetics is ie. Halo tg110 series. for coupling and signal levels.

i have a little experience about them but, of course you must have run a software (like TCP/IP server) in the microcontroller.

i am sure that there are lots of guys known well this issue.

microcontroller with ethernet controller
There are quite a few processor available which does the same. 32 Bit Env will be most suitable.. Power PC ARM are quite standard ..
