Synaptics Launches the xMCU™ Era with the Astra® SR200 Series of Multimodal Edge AI Processors

SYNA
  • Synaptics Incorporated launched the xMCU class of microcontrollers, featuring the new Astra SR200 Series designed for multimodal Edge AI workloads.
  • The SR200 Series combines heterogeneous AI-native compute with integrated custom DRAM scalable to hundreds of megabytes to support larger models on-device.
  • The platform targets next-generation AI wearables, battery-powered sensing, connected cameras, streamers, & industrial vision & voice systems.
  • Core architecture utilizes the Synaptics Torq AI engine, integrating the Google Coral NPU with the first pairing of Arm Cortex-M85 & Cortex-M52 processors.
  • Three pin-compatible product lines are introduced: SR210 (200 GOPS), SR230 (300 GOPS), & SR250 (400 GOPS) to offer scalable performance across different device tiers.
  • Memory architecture pairs up to 8MB of SRAM with extensible high-bandwidth custom DRAM, operating at one-third the power of typical system DRAM.
  • The system includes high-performance & efficiency cores, an optional Cadence Tensilica HiFi 5 DSP for audio, & an always-on domain for sensor fusion.
  • Security features conform to PSA Level 3 & CC EAL4+ targets, offering hardware isolation, cryptographic acceleration, & secure boot capabilities.
  • Connectivity options include high-speed storage interfaces, USB 2.0, industrial Ethernet with IEEE 1588 TSN, & dual CAN-FD interfaces for robotics.
  • The ecosystem supports Zephyr RTOS, open-source MLIR/IREE compilers, & a shared SDK to ensure developer flexibility & software investment preservation.
  • Partnerships with Google Research, Arm, Sonos, Verisure, Jorjin Technologies, & Accton Technology validate the platform for AI wearables, audio, security, & industrial IoT.
