Synaptics launches Astra SR200 with Google's Coral NPU for multimodal AI on wearables and edge devices

Synaptics announced on October 20, 2026 the Astra SR200 series, described by the company as the start of the “xMCU” era — microcontrollers capable of running multimodal AI workloads entirely on-device. The platform combines Synaptics' Torq engine with Google Research's open-source Coral NPU, released in 2025.

What happened?

The three pin-compatible models are:

  • SR210: up to 200 GOPS, optimized for always-on voice and sensing.
  • SR230: 300 GOPS, with vision, display, and optional audio support.
  • SR250: 400 GOPS, with dual vision and display paths for more demanding applications.

The architecture integrates Arm Cortex-M85 and Cortex-M52 cores (the first such combination), up to 8 MB of SRAM, and custom DRAM expandable to hundreds of megabytes, with power consumption reported by the company as roughly one-third that of conventional system DRAM on comparable workloads. The open-source MLIR/IREE-based compiler supports frameworks such as PyTorch, JAX, and LiteRT. Security targets PSA Level 3 and CC EAL4+ certifications.

Yossi Matias, Vice President and Head of Google Research, highlighted the partnership as a way to make edge AI more accessible. Partners mentioned include Sonos, Verisure, and Jorjin Technologies (industrial AR wearables).

Why it matters

Most AI workloads today still rely on the cloud or heavier application processors. Chips like the SR200 aim to allow compact models (examples cited: Gemma 3 270M, YOLO models, and LFM) to run locally on devices constrained by battery, cost, and privacy — from smart glasses and factory cameras to industrial sensors.

The Coralboard SL (based on a previous chip) is already available via DigiKey for about US$99.79. The Coralboard SR with the new silicon is described as forthcoming. The SR200 chips are in the sampling stage; unit prices and volume production schedules have not been disclosed.

Synaptics is in the process of a proposed acquisition by onsemi (approximately US$5.7 billion, estimated close by mid-2027), which could influence the trajectory of the Astra line.

What has not yet been confirmed

There are no independent public benchmarks comparing the SR200 with competitors such as the STM32N6 (STMicro) or RA8P1 (Renesas). Customer statements describe existing work or potential, not confirmed shipments of SR200-powered products. Real-world performance will depend on memory, specific model, and optimization.
