Renesas RE Family
The RE Family of SOTB™ process-based energy harvesting embedded controllers realizes intelligent and battery maintenance-free IoT devices.
The RE Family based on Renesas' innovative SOTB™ process technology realizes ultra-low current consumption in both active and standby mode and fast operation at low operation voltage, which is impossible to achieve with a conventional bulk transistor. The energy harvesting controller and 32-bit CPU also enable the development of intelligent and battery maintenance-free energy harvesting IoT devices.

RE01
The first product based on SOTB™ process technology realizes intelligent and battery maintenance-free IoT devices
The RE01 Group uses Renesas' innovative SOTB™ process technology and realizes both ultra-low active current and ultra-low standby current, and high-speed operation (maximum 64MHz) at low voltage (1.62V), which is impossible with a conventional bulk transistor, and is an embedded controller that can operate by energy harvesting. It is equipped with an energy harvesting control circuit, ultra-low power consumption 14-bit ADC (approx. 4uA), flash (rewrite at less than 1mA), parallel MIP-LCD interface, 2D graphics, UI for clock movement, and security functions such as a trusted secure IP. It also has large-capacity 1.5MB flash and 256KB SRAM that can handle data logging and firmware updates. Therefore, the RE01 Group is suitable for wearable devices, home appliances, building automation, industrial sensor devices, smart locks, asset trackers, and other applications.
