Provides clear audio capabilities to microcontroller-based applications with the new ultra-low-power MSP430™ microcontroller audio capacitive touch booster pack.
Published2012.04.02 13:50TI Korea (CEO Kent Jeon, www.ti.com/ww/kr ) April 2, 2012 – TI announced the C5000™ ultra-low-power digital signal processor (DSP)-based audio capacitive touch booster pack, which adds crisp audio performance for playback and recording functions to microcontroller applications. The new audio capacitive touch booster pack (430Boost-C55audio1) is a plug-in board for use with the $4.30 MSP430™ LaunchPad development kit. As the first TI solution to enable DSP control using only the microcontroller, it allows designers to add audio and other real-time functions to systems without prior DSP programming experience. The booster pack is suitable for low-power applications that utilize recording and playback audio functions, such as MP3 players, home automation, and industrial applications.
Jon Beall, Marketing Director for Single Core Processors at TI, said, “TI has enabled the lowest power consumption for audio applications by combining the industry’s lowest active power DSP with an ultra-low power microcontroller. In addition to low-power benefits, by adding real-time DSP performance to the already widely used capacitive touch booster pack products, microcontroller developers can realize a wide range of possibilities by fully utilizing sophisticated DSP technology without the need for DSP programming.”
The audio capacitive touch booster pack, featuring the C553x ultra-low power DSP and MSP430 value line device, combines the industry's most advanced ultra-low power microcontroller and DSP platform. This allows developers to add DSP capabilities to their microcontroller applications and achieve low power consumption. Developers can easily control the DSP with simple commands via UART by utilizing pre-programmed DSP functions.
Key Features and Benefits of the Audio Capacitive Touch Booster Pack
• The C553x ultra-low power DSP core has a total active power of less than 0.15mW/MHz at 1.05V, the lowest total power in the industry, and enables clear audio/voice MP3 encoding and decoding.
• The MSP430G2452 microcontroller provides 0.5 μA standby power and a wake-up time of less than 1 μs, making it suitable for various low-power applications.
• Users can control volume, select song titles, and record and play audio files through the MSP430 microcontroller's capacitive touch interface
• Provides an enhanced user experience by integrating an LED display, high-speed USB 2.0, and SD/MMC interfaces
• A free capacitive touch library is provided, enabling the implementation of capacitive touch buttons, sliders, wheels, and proximity sensors on all MSP430 microcontrollers, eliminating the need for developers to write complex touch sensing algorithms.
• Easy development work with support for a complete OLED user interface and MP3 recording/playback software library
