Eta Compute is a California-based technology company involved in providing AI edge vision, sensing solutions. They create energy-efficient AI endpoint solutions that enable sensing devices to make autonomous decisions in energy-constrained environments.
The company has released Low Power AI Vision Board for easy evaluation of their technology which is based on Low Power ARM-Cortex-M3 MCU which consumes only ~5uA/Mhz.
I am aware of only one more microcontroller which could compete with it from a low power consumption point of view, which is Ambiq Micro Apollo 4, it consumes 4uA/Mhz.
