LONDON NXP Semiconductors and Phonak have jointly developed a single chip ultra low power radio for use in hearing systems that is being integrated into Phonak's forthcoming range of hearing aids and wireless accessories.
Phonak (Zurich, Switzerland) is one of the oldest and largest global suppliers of hearing systems.
Medical electronics is one of the fastest growing areas of semiconductor development and becoming increasingly important for NXP (Eindhoven, the Netherlands).
The company says advances in magnetic induction radio technology and the CoolFlux DSP were the cornerstones for this collaborative project.
The chip supports data rates of up to 298 kbits/second and bi-directional communication, enabling novel applications such as stereo audio streaming and binaural processing.
"Within this particular project, miniaturization was a key requirement and we worked closely with Phonakís engineers to develop a highly integrated solution, utilizing embedded non-volatile memory and supporting direct operation from a single battery," commented Antoine Delaruelle, senior director and manager of ultra low power solutions at NXP.
