Description
The RL78/G1H microcontroller supports IEEE 802.15.4e/g and has the industry’s lowest power consumption - min. 5.8 mA (3.3 V) at stand-by mode in RF receipt. The balun circuit and filter circuit make the antenna circuit design easy. It enables fewer external parts to be used, reducing costs. The built-in hardware functions for IEEE 802.15.4e/g compliance and especially Wi-SUN can reduce CPU load and ease development. We also offer the RAA604S00 transceiver conforming to IEEE 802.15.4e/g that can be used in combination with a microcontroller.
