I am developing a new product and still very much in the research phase. It is RF based and rightly or wrongly I have decided to go for the native USB option (one of the AT90USBxxx line).
I've looked at the RAVEN USB Stick which uses an AT90USB1287 which of course has 128kb of flash which is very generous but also quite expensive. At the other end of the market I could go for the AT90USB162 which is quite cheap.
However, I don't know whether the Zigbee protocol stack will fit on this processor and even if it does whether there is enough room for the application as well as a USB stack.
Frankly, I have only just reconsidered ZibBee. The data is simple and up until now I have been considering Nordic's nRF2401L
So does anyone have any experience or thoughts on this.
