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-to-market 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.
The MCF532x/7x Embedded VoIP Solution is a complete hardware and software platform based on Freescale ColdFire® microcontrollers for commercial VoIP applications. It includes reference designs, development kits, and middleware that enable rapid integration into devices such as gas pumps, vending machines, ATMs, medical equipment, and VoIP telephones.
The solution ships with the M53281KIT development system, featuring a host board, M53281MOD module, audio, Ethernet, CAN, USB, and an integrated SVGA LCD controller. The kit includes an open‑source uClinux BSP, SIP telephony stack, device‑management middleware, and all necessary licenses, allowing developers to prototype and certify products quickly.
