Edge-AI Audio MCU for Intelligent Voice & Sound Processing
AI-Enabled Microcontrollers Series Astra™ SR80
SYNAPTICS expands its portfolio of AI-enabled microcontrollers with the new Astra™ SR80 series, an Edge-AI audio MCU platform designed for high-quality voice and audio experiences in IoT and embedded applications. The series is built for energy-efficient, privacy-friendly “always-on” intelligence and combines multimodal sensor fusion, continuous context awareness, and intelligent signal processing across multiple power states.
Highly Integrated Architecture for Advanced Audio Processing
The Astra SR80 series features a highly integrated architecture with a programmable Arm® Cortex®-M33 core, integrated audio codec, High-Speed USB, SDIO, and a comprehensive set of audio interfaces. It is further enhanced by dedicated NPU and DSP accelerators, enabling natural and responsive voice-based human-machine interaction. This delivers high audio quality, personalization, and on-device security even in compact form factors.
AI-Powered Audio Features and Faster Time to Market
The SR80 series supports rapid development through turnkey software stacks for advanced audio algorithms such as AI-based noise suppression, along with developer-friendly audio tuning tools. This significantly reduces development time and simplifies the implementation of complex audio features in end products.
Target Applications for Modern Audio and Edge-AI Devices
The Astra SR80 series is ideally suited as a frontend solution for agentic AI headsets, enterprise conferencing systems, soundbars, earbuds, AR (augmented reality) devices, and other audio-centric applications. Together with the Astra SR100 series for vision applications, SYNAPTICS offers a comprehensive portfolio for energy-efficient streaming, audio, and AI edge solutions.
Evaluation Support for Developers
Evaluation kits are available for developers through CODICO, enabling a fast start in development and testing of the SR80 platform.
