 There is any plans to make some PSoC5 family with Ethernet?

 No as of now. May be in Q2, 2011.

The ethernet support is confirmed to be out con Q2 2011? It will be just ethernet hardware support or will also add IP stack?

The MDIO protocol defined for Ethernet can be implemented in the PSoC5 UDB. There has been proposals for implementation of this protocol.

Is there any application note or code example for adding ethernet to Psoc 5?

Thank you in advance

I am not aware of any way of implementing TCP/IP in PSoC 5 natively. I am not aware of any TCP/IP Stack having been ported to PSoC 5 either.

I have, however, successfully integrated TCP/IP, UDP and a web browser into PSoC 5 products by using external devices.

As far as I am aware the PSoC 5 does not have a MAC or a PHY, both of which are physically required to implement ethernet.

My soultion was to use a PIC18F67J60, which has both MAC and PHY and runs the free microchip TCP/IP stack  and connect it to the PSoC using I2C. This means that there is no need to develope your own TCP/IP Stack and it frees the PSoC core for doing other tasks. You will need to add a PHY and MAC anyway, so this method does not increase the component count. The only other components required are an RJ45 Jack with built-in magnetics, a 25 Mhz crystal or oscillator and a few passive components.

There are other ways to implement ethernet - you could just choose your own MAC and PHY chip(s) and code your own stack - but it is a big task. I don't think there is any need to re-invent the wheel.

You mat want to consider a very fast and reliable Ubicom IP2022 Network Processor made by Qualcomm (Ubicom was purchased).

Last stable tool attached as exe  use the Jtag debugger, you need to make a simple parallel port Jtag adapter a few wires.

Micrel offers a number of low cost MAC/PHY controllers -
