Same thing for the 'RC16 - max clock is 16.7MHz (actually the minimum clock period is 60ns....) Seriously, watch out for the minimum frequency too - it's 8MHz for both the '12 and the '16. Good luck finding a cheap co-processor - supply/demand/production volume/ yield/etc. isn't on the consumer's side at this point. -- Neal Sedell
