Design files

Overview

TI's Bluetooth + MSP430 Audio sink reference design can be used by customers to create a variety of applications for low end, low power audio solutions. Some application possibilities - toys, low end bluetooth speakers, audio streaming accessories. This reference design is a cost effective audio implementation and with full design files provided allows you to focus your efforts on application and end product development. Software supported on this reference design includes the TI Bluetooth Stack.

Please note that the MSP430 memory size does not allow any additional application space, so the use case should be audio sink only as described For additional application space please consider using higher flash device, for example MSP430F5438.

Features
  • Enables Bluetooth audio (SBC encode/decode) with low cost, low power MSP430F5229
  • Design offloads audio processing from MCU to the Bluetooth device which enables low power audio
  • Cost effective low end wireless audio solution for under with a 4 layer layout and QFN packages
  • Core of the solution is TI's CC2564 which is best in class Bluetooth performance (+12dBm output power)
  • Design also uses TI's  low power digital input speaker amplifier (TAS2505) & USB charge management device ( BQ24055)
  • CC256x and TI Bluetooth Stack both have Bluetooth Subsystem QDIDs allowing you to only need a Bluetooth End Product Listing

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
