Freescale M53281KIT Reference Platform for Embedded VoIP

Freescale and Arcturus Networks developed an embedded voice-over-IP (VoIP) reference platform to speed time to market for industrial embedded voice applications using VoIP technology. The solution is available as an evaluation and development kit, a ready-to-use module, or a microcontroller (MCU) and software combination for integration into a hardware and software product.

Freescale’s M53281KIT features a host board, VoIP module based on the ColdFire® MCF53281 MCU family, VoIP voice processing software, and a Middleware stack from Arcturus Networks. The comprehensive hardware and software solution is ideal for residential, industrial, and commercial embedded voice using VoIP applications, such as intercom systems used in residential, commercial, and industrial settings.

Incorporating highly optimized management and media middleware from Arcturus, the VoIP reference platform supports a wide range of system configurations, form factors, performance/cost points and target applications in the industrial and consumer markets. The platform’s key features include media signaling that is interoperability certified with leading infrastructure equipment as well as open source PBX implementations, a comprehensive device management system with Web UI, SSL based remote management and simple APIs for application integration. The kit also provides a comprehensive open source uClinux BSP.

Voice processing software developed by Encore Software supports popular voice compression codecs, such as G.711, G729ab, G723 and G.726, and other audio-related functions including echo cancellation, gain control and call progress tones.

The VoIP reference platform demonstrates how the control, performance, and connectivity capabilities of Freescale’s 32-bit MCF53281 and MCF53721 ColdFire MCUs enable embedded designers to add voice functionality to a wide range of applications. The ColdFire platform also can be used to replace existing analog intercom systems while providing improved quality and many additional features. These may include the choice of call routing, various wired and wireless network options, centralized voice-based customer support in multiple languages and access to the public telephone network.

The M53281KIT VoIP reference platform is available for a suggested resale price of $749. The M53281MOD VoIP module is available for a suggested resale price of $99 in 1K quantities.
