Create Bluetooth Speakers With New Dual-mode Bluetooth Modules


Microchip announced the next generation of dual-mode Bluetooth audio chips and modules specially designed for speakers, headsets and gaming headphones. The solution allows audio manufacturers to easily incorporate wireless connectivity in streaming music and voice command applications.

“In addition to expecting high-quality sound, consumers are increasingly demanding a rich user experience that streamlines their communication and interaction with their audio equipment. Our IS206x family is designed to combine the convenience of wireless, portable speakers with a simplistic interface to easily connect and control multiple end devices,” said Steve Caldwell, vice president of Microchip’s Wireless Solutions Group.

The IS206X series is based on a high-performance 32-bit DSP core which allows developers to build sophisticated algorithms for advanced audio and voice processing. The 24-bit digital audio provides high-resolution audio for a richer listening experience.

For sound systems with multiple Bluetooth speakers, the solutions’ ultra-low latency audio streaming will result in tightly synchronized audio playback amongst each speaker.

High definition voice obtained from the solution is ideal for professional headsets. This is achieved with a robust implementation of 16 kHz wideband voice with noise suppression and echo cancellation. There is also a firmware update feature for product software and configuration enhancements over time.

Qualified for Bluetooth v4.2, the IS206X family supports Enhanced Data Rate (EDR) links and the standard audio profiles. The powerful combination of BLE and Advanced Audio Distribution Profile (A2DP) enables smartphone-to-speaker communication via a mobile app. Customized apps enrich the consumer’s experience by providing creative control features such as pairing, remote control and real-time audio effect adjustments.

The IS206X family is available in several offerings, allowing customers to tailor their wireless needs. For designs that require a turn-key solution for fast time-to-market, customers can take advantage of the chip’s powerful features by choosing a module configuration with either a Class 1 or a Class 2 device.

All modules are fully certified with the following regulatory bodies: United States (FCC) and Canada (IC), European Economic Area (CE), Korea (KCC), Taiwan (NCC) and Japan (MIC).

Microchip also introduced three Evaluation Boards for the IS206x family in order to enable easy development – the BM-62-EVB , BM-63-EVB, BM-64-EVB-C2, and BM-64-EVB-C1.
