Achieving long battery life in IEEE 802.15.4g applications is a challenge for system designers. Renesas has developed a solution for IoT edge devices that can operate for up to 10 years off of a primary battery. The ultra-low power RL78/G1H MCU supports the IEEE 802.15.4g Sub-Gigahertz communications standard and interfaces easily to a variety of sensors. This reference design can shorten the time to prototype for gas metering, logistic tracking or other edge sensing applications.

System Benefits​:

  • Time to market shortens by approximately 1 year.
  • Up to 10 years of battery life for edge device communications using Renesas’ world-class RL78/G1H, due to its wide voltage range and low current drain.
  • Supports Renesas’ RF switch, RF transceiver and MCU for applications including gas metering, logistics tracking and more.
