Synaptics unveils Astra SR200 processors with Google's open-source Coral NPU

On October 20, Synaptics launched the Astra SR200 family of three processors, integrating Google's open-source Coral NPU technology for devices such as smart glasses, cameras and industrial sensors. The companies also announced broader availability of the Coralboard platform, enabling local experimentation with models including Google's Gemma.

The SR200 family comprises the SR210, SR230 and SR250, delivering 200, 300 and 400 GOPS of AI performance respectively. The chips pair Arm Cortex-M85 and Cortex-M52 cores with Google's Coral NPU, and integrate up to 8MB of SRAM plus custom DRAM configurations reaching hundreds of megabytes; the upcoming Coralboard SR board supports up to 256MB. Synaptics says its custom memory architecture consumes about one-third the power of conventional system DRAM in comparable workloads, though independent benchmarks are not yet available.

Google Research open-sourced the Coral NPU architecture in October 2025, using the RISC-V instruction set and an Apache 2.0 license. Synaptics is Google's first commercial silicon partner. The company's Torq compiler, built on MLIR and IREE, supports models from frameworks such as PyTorch, JAX and LiteRT. Targeted workloads include Gemma 3 270M, Liquid AI's LFM2.5 family and Ultralytics' YOLO vision models.

The Coralboard SL developer board, based on the Astra SL2619 processor, is now available through DigiKey for $99.79. The Coralboard SR board with the SR250 is described as forthcoming. The SR200 family is currently in the sampling stage; pricing and volume production schedules have not been disclosed.
