RE Family, The World’s Most Energy Efficient MCUs with Arm® Cortex® M Core Implemented on Silicon on Thin Buried Oxide (SOTB)

705 ULPMark-CP score certified by EEMBC ULPMark™ benchmark

REファミリ

The RE Family based on the Silicon on Thin Buried Oxide (SOTB™ ) process technology realizes both ultra-low current consumption in both active and standby mode and high speed CPU operation (64MHz) at low voltage (1.62V) , which is impossible to achieve with conventional bulk silicon processes. The RE01 has been certified by EEMBC to have the highest score of 705 for the ULPMark-CP by the EEMBC ULPMark™ benchmark, which has been developed to provide a standard method to compare the energy efficiency of ultra-low power MCUs. In addition, the built-in energy harvesting control circuit enables the equipment to operate from energy harvesting power sources with only weak ambient energy.

The RE Family can significantly extend battery life and deliver high performance even for small batteries and energy harvesting power supplies that can supply only a small amount of current. The RE Family is suitable for many IoT applications such as hybrid watch, smart home/building, healthcare, smart agriculture, structure monitoring, and trackers
