ONiO develops ultra-low-power microcontrollers designed to operate from ambient energy, with its flagship product ONiO.zero cold-starting from under 1µW and running at about 22µW/MHz. The company integrates a RISC-V CPU, radios, power management, security, memory and other functions on a single die, replacing dozens of discrete components. ONiO.zero has been tested in solar keyboards, electronic shelf labels, air quality sensors, asset trackers and soil sensors. The startup aims to eliminate batteries from many IoT devices and enable more sustainable, minimalist power designs. To support commercialisation it is scaling volume production and shipping developer kits and reference designs so engineers can build applications. Founded in 2016, ONiO says the technology works in real-world applications and is moving to mass production.
