The SR80 series accelerates time-to-market, with turnkey support for advanced algorithms such as AI-based Noise Reduction and developer-friendly audio tuning software kits. This powerful combination makes the Astra™ SR80 series ideal as front ends for Agentic AI headsets, enterprise conferencing systems, soundbars, earbuds, augmented reality devices, and other audio-centric applications. Together with the AI-native Astra™ SR100 series, which brings vision processing to the Edge, Synaptics offers a rich portfolio of solutions for high-quality, low-power, streaming vision and audio at the Edge.
The SRW1500 extends the Synaptics Astra™ MCU portfolio by pairing AI-native compute with next-generation wireless connectivity. The Astra™ SRW1500 series is among the industry’s first single-chip AI MCU platforms with integrated Wi-Fi® 7 connectivity, powered by open, developer-friendly software to enable continuous AI, starting at the far Edge of the IoT network.
The SRW1500 features the Arm® Cortex®-M52 with Helium™ DSP, which is a highly area- and energy-efficient implementation of the Armv8.1-M architecture, running at 200 MHz, alongside a 200 MHz, 50 GOPS Arm® U55 NPU for efficient on-device inferencing. With 1 MB of on-chip SRAM, the SRW1500 SoCs are designed to support pre-processing and accelerating sensor-fusion and signal processing workloads such as noise cancellation, beamforming, feature extraction and Wi-Fi sensing. With PSA Level 3 certified Root-of-Trust security and advanced power management features, the Astra™ SRW1500 AI MCUs deliver a robust processing platform for embedded applications that bring together multimodal sensing and intelligent connectivity.
“Extending AI-native compute across every tier of the Edge portfolio is critical to scaling our platform,” said Vikram Gupta, SVP & GM, Edge Compute & Connectivity Division, Synaptics. “Our new Astra™ SR-Series Audio MCUs and SRW Series integrated Wireless MCUs bring premium features such as multimodal sensing and secure connectivity to the value end of the market, enabling customers to standardize on a single, production-proven architecture.”
