Renesas Electronics Corporation has introduced the RE01B MCU with Bluetooth 5.0 support, extending its RE Family of 32-bit ultra-low-power consumption MCUs. Developed using its SOTB process technology, the new Bluetooth-capable MCU is excellent for energy harvesting systems and intelligent IoT devices that need to perform constantly at very low power levels with no need to replace or recharge batteries. The MCU makes it simpler to implement regular data management and firmware updates over Bluetooth while keeping ultra-low power consumption and prolonging the battery life.

“Managing battery maintenance and replacement is one crucial hurdle ahead of the widespread adoption of ultra-low-power IoT devices that are expected to run for long periods with limited or no maintenance,” said Shigeki Kato, vice president of the Enterprise Infrastructure Business Division at Renesas. “I am excited that the addition of the new Bluetooth-capable RE MCU will remove the needs for battery maintenance in a broader range of systems and meet the needs of IoT system manufacturers.”

Applications incorporate compact healthcare devices, including pulse oximeters and biomedical sensor patches; remote controls with voice recognition capabilities, and smart meter modules. Also, the device is ideal for IoT devices that need constant operation, period data collection and updates, such as devices for monitoring the elderly, children or assets in transit.
