from the document:
"The fundamental innovation of the ultra-high-speed flash microcontroller is the use of only one clock per instruction cycle In addition to improved efficiency, it can operate at a maximum clock rate of 33MHz."

high - Ok, ultra - no way. This is one third of the speed of a SILabs F120-F123 and F130-f133.

BTW re "fundamental innovation" Cygnal (now SILabs) had one clockers first.

So, it is not ultra and it is not an innovation except an innovation in hyperbole.

Erik

So, apparently there were grand plans for a device in this family that would match or exceed the performance of the SILabs devices you mention, thus perhaps justifying the "ultra" designation. See The Fast Microcontroller: A Decade of Growth and Innovation. See figure 5 on page 9 for what apparently never happened.
