Microcomputer chip “ ONiO.zero '' perfect for “ batteryless IoT '' that produces electricity by itself appears

2020 will be the next generation communication standard5GStarts in Japan and Things Connect to the InternetIoTHowever, it is thought that IoT devices will need more power supply, and the fact that devices can be placed only in places where power can be secured is one of the factors that reduces the possibility of IoT.

A battery-less microcomputer chip developed by ONiOONiO.zero"is. 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 adopted isRISC-VThe clock frequency varies depending on the available input voltage, and is 24MHz at 1.8V, 6MHz at 1.0V, and 1MHz at 0.8V.

Wireless communication standards includeBluetooth Low EnergyIs used for communication with peripheral devices.I2CAndSPI,UARTYou can use industry standard communication standards such as.

The key energy source is the high-frequency rectifier inside the chip, which corresponds to the 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.
