Add crystal clear audio to microcontroller-based applications with TI’s new Audio Capacitive Touch BoosterPack for ultra-low-power MSP430 microcontrollers

It is the first solution from TI where a DSP is solely controlled by a microcontroller which allows designers to add audio and other real-time features to their system without DSP programming experience. The BoosterPack is ideal for low-power applications that use record and playback audio functions such as MP3 players, home automation and industrial applications.

“TI is making it possible to achieve rock-bottom power consumption for audio applications by combining the industry’s lowest active power DSPs and ultra-low-power microcontrollers,” said Jon Beall, marketing director, single-core processors, TI. “In addition to the low power advantage, the real-time DSP performance added to the already-popular Capacitive Touch BoosterPack means the possibilities are endless for microcontroller developers wanting to take full advantage of sophisticated DSP technology without programming on the DSP.”

Featuring a C553x ultra-low-power DSP and an MSP430 Value Line device, the Audio Capacitive Touch BoosterPack combines the industry’s leading ultra-low-power microcontroller and DSP platforms. This allows developers to add DSP functionality to their microcontroller applications while ensuring the low power consumption. Developers can easily control the DSP through simple commands using the UART by leveraging the pre-programmed DSP functions.

Key features and benefits of Audio Capacitive Touch BoosterPack

• C553x ultra-low-power DSP, the industry’s lowest total power DSPs with total active core power < 0.15 mW/MHz at 1.05V, enables crystal clear audio/voice MP3 encode and decode.
• MSP430G2452 microcontroller offers standby power of 0.5uA and <1μs wake-up time for a wide range of low-power applications.
• MSP430 microcontroller capacitive touch interface allows users to control volume, select song titles and record and playback audio files.
• Integrated LED display, high-speed USB 2.0 and SD/MMC interfaces offer an enhanced user experience.
• Free capacitive touch library enables capacitive touch buttons, sliders, wheels and proximity sensors on all MSP430 microcontrollers, eliminating the need for developers to create complex touch-sensing algorithms.
• Supported by a complete OLED user interface and MP3 record/playback software library, easing development.
