The rise of AI-driven IoT devices is outpacing the capabilities of existing microcontroller units (MCUs).Current 32-bit MCUs struggle to handle AI workloads effectively, leading to a fragmented ecosystem.Existing AI-enabled devices are often repurposed from other applications, not optimized for IoT's power requirements.Traditional AI MCUs have rigid architectures that compromise energy efficiency in IoT environments.To address these challenges, a new class of MCUs blending sensing and AI compute is necessary.Synaptics introduced the Astra SR-Series AI MCU platform for IoT, featuring a multi-gear architecture.The SR100 Series MCUs have three domains for different power levels: ULP Always-On, Efficiency, and Performance.The domains balance energy efficiency with AI processing capabilities, optimizing power consumption.The SR100 series employs intelligent gearing algorithms for context-aware AI computing, improving scalability and efficiency.Standardized development practices ensure compatibility with existing IoT ecosystems.
