WAAS-based MCU amps performance of wireless earbuds and hearables

September 18, 2018 By Aimee Kalnoskas Leave a Comment

WAAS-based MCUCypress Semiconductor Corp. introduced a Bluetooth audio offering that brings leading-edge performance to wireless earbuds and hearables. Based on the new Wireless Audio Stereo Synchronization (WASS) application and the CYW20721 Bluetooth and Bluetooth Low Energy (BLE) Audio microcontroller (MCU), the solution provides robust connections for differentiated performance in wireless earbuds. The MCU features a link budget that is 6 dB better than competing chips, resulting in up to twice the range. The extended range and the WASS application combine to enable superior cross-body performance, giving users uninterrupted audio on their earbuds with their smart device in their back-pocket or on their wrist. The MCU also operates at nearly 50% lower power consumption than competing chips, enabling twice the playback time or the use of smaller batteries in sleeker form-factors.

The novel WASS application is available in Cypress’ WICED Pro software development kit (SDK), the latest version of its all-inclusive WICED SDK that provides developers with a turnkey solution to get products to market quickly.

“Stereo synchronization has proven to be a difficult challenge in Bluetooth earbuds, as even the slightest connection loss can result in a frustrating user experience,” said Brian Bedrosian, vice president of marketing for the IoT Business Unit at Cypress. “Cypress has solved this problem with our WASS solution, which uses the industry’s best connectivity scheme to deliver a flawless user experience. Our lead customers are ecstatic about the performance they’re getting and we believe consumers will be too when their earbuds deliver a wire-free and high-fidelity audio experience this holiday season.”

The highly-integrated CYW20721 chip employs WASS software that leverages 15 years of innovation and development experience with headsets, mobile devices and virtual reality products. The multi-mode Bluetooth/BLE MCU also includes essential consumer features such as voice commands and cloud-based voice services.

Cypress’ WICED Pro development platform supports an ecosystem that includes multiple audio codec partners, allowing for price and performance differentiation, including echo and noise cancellation. The WASS software further benefits from advanced wireless error correction algorithms in WICED Pro, offering high-fidelity connections.
