Expanding the company's SimpleLink Bluetooth CC256x portfolio, Texas Instruments has announced Bluetooth 4.1 certified modules and audio reference designs for rapid prototyping, development and production. The solutions include updates such as on-chip audio encoding and decoding as well as new Bluetooth low energy capabilities.
Now the SimpleLink Bluetooth dual mode portfolio will allow customers to create a range of innovative audio solutions for applications such as toys, Bluetooth speakers, audio streaming accessories, sports/heath fitness and more.
Based on the CC2564 dual mode solution, the SimpleLink Bluetooth modules include all components that allow it to be FCC/IC and CE certifications. Furthermore the CC256x family has been updated with new on-chip audio processing allowing for subband coding encode and decode to be offloaded from the external host. By keeping the audio path external to the host microcontroller, the solution allows a greater range of suitable host MCUs, driving down system cost and power consumption.
The TI reference designs for low cost speakers and toy applications include the Bluetooth audio sink reference design. This utilises the SimpleLink CC256x device, an ultra-low power MSP430F5229 MCU with 1.8V glueless interface to 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, which enable developers to quickly add audio streaming capabilities from a phone or tablet to their products.
Additionally, TI’s Bluetooth audio source reference design, expected later 2Q, enables the sourcing of Bluetooth audio. It features the SimpleLink CC256x device, an ultra-low power MSP430F5229 MCU, a TLV320ADC3101 stereo ADC converter and bq24055 single cell Li-ion battery charger.
SimpleLink CC256x Bluetooth solutions are available now. The CC2560 is priced from $1.86 (USD) in 1,000 unit quantities; the CC2564 is priced from $2.14 (USD) in 1,000 unit quantities; and the CC2564MODN is priced from $4.97 (USD) in 1,000 unit quantities (available in Q2).
