Audio platform integrates microcontrollers and firmware IP

Atmel has announced a DAP (digital audio platform) for consumer, automotive, and industrial applications. The DAP provides audio equipment and mobile accessory OEMs, a hardware and firmware solution that simplifies the task of designing digital audio equipment, claims the company. The DAP is implemented with the company’s AVR UC3 microcontrollers tailored for audio applications such as smartphone and media player docking stations. It integrates dedicated microcontrollers, evaluation kits and firmware IP. The firmware IP includes control and streaming interfaces for a selection of smartphones and portable media players as well as MP3, windows media audio and advanced audio coding decoders to decode compressed music files; USB protocol stacks; and a file system to navigate through mass storage devices such as USB Flash disks or SD (secure digital) cards. The DAP is suitable for docking stations, USB mass storage, SD card playback, car stereos, USB speakers, microphones, and voice and music equipment. Other applications include mobile accessories which are connected to smartphones or tablets that use the same underlying technology, claims the company. The microcontrollers also support the Atmel QTouch library for easy implementation of differentiating user interfaces for capacitive touch buttons, sliders and wheels, according to the company.
