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.
