Small, low power microcontrollers (MCUs) in the RL78/G11 group will enable users to easily and more quickly prototype and develop systems that support low-power sensor hubs and sensor application systems, says Renesas Electronics. Sensor hubs are designed to connect to multiple sensors and convert the sensor output signals to digital data, and are used in computer operating environment monitoring for data centre thermocouples in the industrial area, wearable health management devices in the healthcare field, and environmental sensing in greenhouses and factory farms in the agricultural industry.

Contactless wireless charging brings convenience to wearables
To charge low power applications, such as hearing aids and other wearable devices that require resistance to water and dust, Renesas has developed the RAA457100 power receiver IC and a power transmitter IC (the RAA458100). Each includes all the functions needed for wireless charging on a single chip. An evaluation kit is also available.
PMIC uses proprietary technique for energy harvesting
Using proprietary energy management technology, the AEM10940 PMIC comprises a low power boost converter (at 94 per cent efficiency levels), voltage reference, energy management and LDO regulator elements. Its cold-start circuitry enables it to be brought into active operation even when there is minimal energy left, says e-peas. An input voltage of 380mV and just 11microW of power are more than sufficient, it adds.
Small MEMS oscillators boast lowest power operation
MEMS oscillators from Microchip, the DSC6000 family, are claimed to be the smallest in the industry and with the lowest power consumption over 2.0kHz to 100MHz.
