Functional Differences Between
DSP56302 and DSP56309 (formerly
DSP56302A)
1 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.
2 Differences Overview
The primary functional differences between the DSP56302 and
the DSP56309 are due to inherent differences between the two
design technologies. Table 1. compares the two chips.
