Hello all,
I am looking for an ARM processor with integrated Ethernet MAC _and_ PHY. Appreciate any suggetsions.
Thanks, Abdul
ARM with Ethernet MAC+PHY?

The AT91SAM7X could be a good choice.
Nice processor, but no PHY.
Regards, Richard.

*Now for ARM CORTEX M3!*
Has it to be an ARM, if not => ColdFire 5223x

Use @monlynx.de instead !
AT76C910 will do , but wont be available in low volume. You will not gain any board size, since you will need external memory. You will not gain any power consumption benefits (see above) You will not gain any price advantage, since the 910 is more expensive than the SAM7X.
So why do you need the integration?

Is it the correct partnumber ? Can't find it on

Or do I have to be a first tier customer ? :-)

Yes, it is an ASSP and they are normally not on the web site. You need large volume to get it (50ku).

No, That is a VoIP chip with WLAN.

I have to second that idea:

Thanks for all suggestions.
CF5223x looks like a good chip. Reason for preferring ARM is GCC support and prior experience with the architecture. An integrated PHY has the obvious advantages of lower chip count, smaller PCB, and fewer failure points. Does GCC support ColdFire?
Regards, Abdul
of course simply google for coldfire+gcc you will be surprised. Heinz
He shouldn't be too surprised - after all, the original gcc target was the 68k family. The ColdFire is also the original target for ucLinux (although it is not suitable for small integrated devices like the CF5223x), even though the Arm port is probably more popular these days.
