Today that game is sort of different. While still more in sampling than in volume production, the SAM7 devices (at least the S32) do exist and are definitely interesting for many applications. > I also designed a demo board (mainly for USB use) but project is > collecting dust on my desk: no samples.

While I am a LPC-fan, the presentations I saw from Philips announce the USB device LPC2148 late in Q2, don't think that Atmel will take that long but on the other hand the LPC2138 with an external USB would do the job today if you need more than the 64k Flash (e.g. 512k flash). > > What I don't like about SAM7 is how it handles SPI communication.
