Product Overview
The Synaptics Astra SR200 Series of AI-native MCUs delivers high-performance, low-power multimodal compute for wearables, connected cameras, and industrial vision and voice systems. Powered by the Synaptics Torq™ AI engine with Google Research’s Coral NPU™, the series provides 400 GOPS of AI inference alongside Arm® Cortex®-M85 and Cortex®-M52 cores. Its integrated vision, display, and audio pipelines support applications such as camera processing, rich user interfaces, wake-word detection, and voice processing. A multi-die system-in-package design combines compute, power management, and high-capacity memory to improve design efficiency and reduce system power and cost. With advanced security, broad connectivity, Zephyr RTOS support, and an open-source NPU compiler, SR200 MCUs enable a new class of Edge and physical AI devices.
