When searching, I came across several pages on the net indicating that the AVR32 chips had a very fast SPI speed. The datasheets seem to indicate that SPI output can be up to master clock frequency, but it seems that every other Atmel MPU only works at up to [Master Clock / 2] which would be 30 or 33 MHz for the UC3A and B chips. Has anyone ever tried running the SPI on one of these chips at top speed and found out what happens? Strange how you can get 66 MHz SPI memory chips, but yet hardly any MPU seems to support that speed.
