Microcomputer chip `` ONiO.zero '' perfect for `` batteryless IoT '' that produces electricity by itself appears
ONiO.zero Offers Up to 24MHz of RISC-V Microcontroller Performance on Nothing But Harvested Energy-Hackster.io
ONiO.zero is a battery-less microcomputer chip developed by ONiO . It has very low power consumption and can generate its own power, so it does not require batteries such as coin-type batteries or lithium-ion batteries. Battery-based devices require battery replacement maintenance, but ONiO.zero can power sensors and devices for years without having to worry about such maintenance. In addition, small batteries do not need a battery that occupies most of the capacity, and high affinity with clothes, watches, and medical devices is attracting attention.
The architecture employed is RISC-V, where the clock frequency varies with the available input voltage, 24 MHz at 1.8 V, 6 MHz at 1.0 V, and 1 MHz at 0.8 V.
Bluetooth low energy is adopted as the wireless communication standard, and industry standard communication standards such as I2C , SPI , and UART can be used for communication with peripheral devices.
The key energy source is the high-frequency rectifier inside the chip, which corresponds to the frequency band of 800/900/1800/1900 / 2400MHz. In Japan, bands 8, 18, and 19, which are the frequency bands of mobile phones, are compatible, so it can be operated without batteries by energy harvesting unless it is in a very mountainous area.
