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.

Differences Overview
The primary functional differences between the DSP56302 and
the DSP56309 are due to inherent differences between the two
design technologies.
