Freescale Kinetis based VoIP MCU design from Arcturus

Arcturus has announced the availability of a microcontroller (MCU) based solution for the creation of VoIP and distributed IP audio end-points. The solution specifically targets two-way, full duplex voice communication, hands-free intercoms, speakerphones, public address (PA) systems, mass notification and IP speakers. The solution, developed in collaboration with Freescale Semiconductor and Consilient Technologies, consists of a Freescale Kinetis K60 microcontroller based on ARM Cortex M4 technology combined with an audio subsystem specifically designed for voice communication. The microcontroller is preloaded with VoIP and Mbarx-M2M (machine-to-machine) middleware which runs on the MCU’s internal flash and SRAM with no need for a co-processor or additional memory components. The solution is available as development kit, a production board, a module or a pre-programmed MCU. “An MCU-based solution achieves a simpler overall design, better system integration, a lower cost bill-of-materials and reduces boot time,” said David Steele, product manager. “By enhancing the VoIP capability with our Mbarx-M2M stack we can voice-enable ‘Internet of Things’ applications including home control and multi-service intercoms, two-way voice security applications and healthcare devices for assisted living.” The voice middleware includes a full SIP/RTP VoIP stack using peer-to-peer or PBX...
