表1-1 MCF532x系列主要配置

Freescale Semiconductor proudly introduces an addition to the 68K/ColdFire family of
embedded controllers, a complete hardware and software solution for commercial VoIP
applications based on the popular MCF532x products. The solution is designed to help
embedded developers reduce time-tomarket by providing a complete hardware and software solution that can function as a reference design or a take-to-market product
platform. This flexibility gives developers the option to integrate fully developed module
boards or design their own application.

The system includes all required software components to develop a feature-rich product
and does not require an NRE, lowing overall system cost. The solution is supported by
a stand-alone development kit that is ready to demo out-of-the-box. This easy to use,
cost-effective solution will help simplify development and allow designers to enable
more applications with VoIP capability.
