Bluetooth 4.1 Modules Enrich Audio Experience

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.
