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. © Motorola, Inc. 1996, 2001 For More Information On This Product, Go to: www.freescale.com Functional Differences between DSP56302 and DSP56309 (formerly DSP56302A) Freescale Semiconductor, Inc.
