Building on the company’s IS202X portfolio of highly integrated SoC devices and modules, Microchip announces its next-gen dual-mode Bluetooth audio products. Uniquely engineered for speakers, headsets and gaming headphones, this flash-based platform offers ample flexibility and powerful design features, allowing audio manufacturers to easily incorporate wireless connectivity in streaming music and voice-command applications.

A high-performance 32-bit DSP core provides the framework to develop sophisticated algorithms for advanced audio and voice processing. The 24-bit digital audio support delivers high-resolution audio to consumers for a richer listening experience. Sound systems comprised of multiple Bluetooth speakers benefit from ultra-low latency audio streaming, resulting in tightly synchronised audio playback amongst each speaker. Applications such as professional headsets benefit from high-definition voice, achieved with a robust implementation of 16kHz wideband voice with noise suppression and echo cancellation. The added firmware update capability allows for product software and configuration features enhancements over time.

Qualified for Bluetooth v4.2, the IS206X family supports enhanced data rate 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. Customised 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, priced at $99.99; BM-63-EVB at $124.99; BM-64-EVB-C2 at $124.99; and BM-64-EVB-C1 at $124.99 are all available now.

In production are a total of 10 devices, three IS206X devices in volume production in 7x7 LGA or 8x8 LGA packages and a total of seven unshielded or shielded, Class 1 or Class 2, modules are also in volume production.
