Enable new functionalities in microcontroller applications, including crystal clear audio with playback and recording capabilities with the C5000™ ultra-low-power digital signal process (DSP)-based Audio Capacitive Touch BoosterPack. This new Audio Capacitive Touch BoosterPack is a plug-in board for the MSP430™ microcontroller LaunchPad, where the DSP is solely controlled by the microcontroller. The BoosterPack is ideal for low-power applications that use record and playback audio functions such as MP3 players, home automation and industrial applications.

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 new development tool will allow you to add DSP functionality to your microcontroller applications while ensuring low power consumption. You will be able to easily control the DSP through simple commands using the UART by leveraging the pre-programmed DSP functions.

• C553x ultra-low-power DPS, 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.
• MSP430 microcontroller offers five power modes with the industry’s lowest standby power options of 0.4uA and < 1us wake-up time for a wide range of low-power applications.
• MSP430 microcontroller capacitive touch interface allows you 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 you to create complex touch-sensing algorithms.
• Supported by a complete OLED user interface and MP3 record/playback software library, easy your development cycle and time to market.
