Freescale Rolls Out Reference Platform for Embedded VoIP

Freescale has introduced an embedded voice-over-IP (VoIP) reference platform solution designed to speed time to market for industrial embedded voice applications using VoIP technology. Developed in collaboration with Arcturus Networks Inc., 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 customer’s hardware and software product.

Freescale’s M53281KIT is a VoIP reference platform, evaluation and development kit featuring a host board, VoIP module based on the ColdFire® MCF53281 MCU family, VoIP voice processing software and a Middleware stack from Arcturus. 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.

“As VoIP technology has matured and entered the mainstream of the communications market, system developers look for highly integrated, market-ready solutions optimized for performance and cost effectiveness,” said Jeff Bock, global product marketing manager of Freescale’s Consumer and Industrial Microcontroller Division. “The VoIP reference platform co-developed by Freescale and Arcturus is designed to enable ‘out-of-the-box’ productivity for developing innovative embedded-voice applications.”

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.

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 combination of Freescale’s highly integrated ColdFire MCUs, our board design capabilities and middleware software has resulted in a VoIP reference platform that allows product developers to integrate VoIP without needing to become media, signaling or endpoint management experts,” said Michael Durrant, vice president engineering, at Arcturus Networks Inc. “The comprehensive reference platform includes all system components and software needed to build industrial and residential VoIP systems, quickly, easily and at cost-effective price points.”
