Featuring three power levels, the SR-Series MCUs scale Astra AI-Native hardware and open-source software to accelerate the development of low-power, cognitive IoT devices.
Intended to accelerate the development of low-power, cognitive IoT devices, Synaptics extended its Astra AI-Native platform with the SR-Series high-performance adaptive microcontrollers for scalable context-aware edge AI. The deliver 100-GOPS performance with a high level of power efficiency that leverages ultra-low-power, always-on technology to deliver intelligence at every power level.
Features include an Arm Cortex-M55 core and the Arm Ethos-U55 neural processing unit. The SR-Series is supported by the Astra Machina Micro development kit and open-source SDK.
The MCUs are optimized for multimodal consumer, enterprise, and industrial IoT workloads with accelerators and adaptive vision, audio, and voice algorithms They offer a range of peripherals that include multiple camera interfaces to help minimize system cost while enabling integration into a wide range of devices. The Synaptics Astra AI-Native compute platform for the IoT combines scalable, low-power compute silicon for the device edge with open-source software, tools, and Veros wireless connectivity.
The SR-Series consists of three MCUs—the SR110, SR105, and SR102—each able to serve a range of multimodal application requirements, with a Cortex-M55 core and Arm Helium technology running up to 400 MHz. Furthermore, the SR110 has a Cortex-M4 core and Arm Ethos-U55 NPU (it's sampling now); the SR105 has an Ethos-U55 NPU; and the SR102 is a single Cortex-M55 device.
Also in the mix are up to 4 MB of system memory, including ULP AON memory; streaming vision and audio processing; MIPI-CSI camera input and passthrough; low-power image signal processing; and secure OTP, TRNG, AES-256, RSA-4096, and SHA-512.
An Army veteran, Alix Paultre was a signals intelligence soldier on the East/West German border in the early ‘80s, and eventually wound up helping launch and run a publication on consumer electronics for the U.S. military stationed in Europe. Alix first began in this industry in 1998 at Electronic Products magazine, and since then has worked for a variety of publications, most recently as Editor-in-Chief of Power Systems Design.
