Purpose of this Document
To meet the increasing demands for higher performance and lower power consumption, an advanced DSP56302 has been designed; it is was formerly known as DSP302A; it is now designated DSP56309. The new part is designed to be a functional replacement for the DSP56302. This document summarizes the differences between the DSP56302 and the DSP56309.
