w5100 cortex 3

Hi,
I want to do interafcing between microcontroller and ethernet.
Can anybody tell me which controllers support ethernet.
please give the manufacturer names and controller model numbers.

Thanks,
viswanath.

check this link from NXP

w5100 interface slow cpu

You can also check Luminary micro's Cortex-M3-based microcontrollers.

w5100 udp atmel

Take a look at the W5100 from Wiznet. Allows you to link any cpu to Ethernet

Ceck out with ATMEL 90 series AT MEGA, and ATTiny..
one of them will be suitable for your application..

HI,

ST micro electronics has STR9 with inbuilt ethernet driver. If you are too comfortable with 8051 try silicon laboratories(www.silabs.com) which has a large collection of 8051 compatible controllers which can be interfaced with external ethernet IC such as CP2201. The TCP/IP stack needed for ethernet application is supplied by silicon labs itself.

inbilt ethernet 8051 controller

yah! H_R_D is right!^^

the ATMEL products such as AT90xx, ATmegaxx and ATTinyxx series can used it to interface to Ethernet!^^

Hi,
Thanx to everyone for replying...

i am choosing atmel 89s8252 and ENC28J60 ethernet controller from MICROCHIP.
Both has SPI interface compatibility.

does the above will be best?
how to implement tcp/ip stack? does the ethernet controller will have inbuilt tcp/ip stack r i have to implement on my own?
i have gone through the datasheets,but i dint get the information to start

i am little bit confused with tcpip.
can any one of u please tell me how to start tcpip programming r what i need to kinow before starting this interface using spi protocol.

thanks & Sincerely,
viswanath

hi

I worked with PIC18f97j60
and a development board:
PICDEM .NET 2

You can also visit www.nxp.com to have a look at their ARM7 chips

 

[nguyenngochuan]

you can use PIC ENC28J60 of microchip.

Hello,

The chip of your choice 89s8252 is quite a slow chip.
Not as fast as a PIC18F or a AVR ATmega micro. If you require only UDP , IRP, ARP kind of things then its okay to go ahead. But if you application require web service etc then you require a faster micro.

Still if you want the continue with your micro then you should look for W5100. Its quite easy and also available easily in INDIA. There is another chip which is a memory based one RTL8019AS which has been used by many to implement the Enternet interfacing with 8051.

Actually your choice will probably depend on which family of µControllers you're familiar with. If you're familiar with ARM you can check the NXP's LPC2300/2400
Some 8051 chips support Ethernet. PIC, AVR, etc are other options.

Hi,
Please go through LPC2364/66/68 from NXP which has ethernet,USB, CAN, SPI,SSP,UART etc, with ARM Core. which works fine with my project.
