New modules and audio reference designs added to Texas Instruments’ SimpleLink Bluetooth CC256x family help accelerate prototyping, development, and production of audio solutions. The Bluetooth 4.1-certified modules/reference designs include updates such as on-chip audio encoding and decoding, as well as new Bluetooth low-energy capabilities. On-chip audio processing allows for subband coding (SBC) encode and decode to be offloaded from the external host. Keeping the audio path external to the host microcontrollers (MCUs) enables a greater range of suitable host MCUs. Modules are based on the CC2564 dual-mode solution, and include all components to meet FCC/IC and CE certifications. Reference designs include the audio sink reference design, which uses the CC256x device, a low-power MSP430F5229 MCU with 1.8-V glueless interface to the CC256x, a TAS2505 digital input class-D speaker amplifier, and bq24055 single-cell, Li-ion battery charger. All are supported with a Bluetooth stack, profiles, and sample app. The Bluetooth audio source reference design (expected later in the second quarter) features the CC256x device, MSP430F5229 MCU, TLV320AD3101 stereo analog-to-digital converter, and bq24055 battery charger.
