Renesas' RL78/H1D, RL78/L1x Series, and RL78/G1x Series of MCUs are famous for low power consumption. They also incorporate a highly reliable watchdog timer (WDT) and on-chip oscillator circuits with minimal susceptibility to oscillation errors, in order to increase the fail-safe functionality of the MCU. These MCUs are suitable for the development of gas meters demanding stable operation with a high level of reliability.
