Interesting looking Peripheral mix.
x4 mode for SD is nice to see, as is the fast SPI/SSC and
uarts with a SYNC mode is also an emerging feature.
HS USB joins their AVR32, so now Atmel have two FLASH
families with HS USB.
Timers look a little light, at just 16 bits and only 3 ?!
There is a Quadrature mode, hidden in the fine print
Even the 99c NXP device has 2 x 32 bit and 2 x 16b Timer/counters.
