Hello, NXP.I really love your products, especially MC56F8346.I used to use MC56F8346, but its calibration arithmetic is trouble.This time come here to have a consult whether there is a DSP/DSC product support fractional arithmetic, especially can compatible with MC56F8346?

In addition, I heard that MC56F84xx have a good preformance, and support fractional arithmetic. Is there  a big difference between  MC56F8346 and MC56F84xx in pin relationship?Can be compatible?Which one of them is more popular?
