RL78/G13 Group microcontrollers employ the RL78 core which realizes high processing performance while delivering the lowest power consumption in their class.
A high-precision (±1%) on-chip oscillator makes 32 MHz CPU operation possible, and built-in features such as a reset circuit, a low voltage detection circuit, a watchdog timer, and data flash with background operation function help to lower the total cost of building a system and contribute to more compact size and lower power consumption.
In addition, abundant functions for supporting functional safety, such as an A/D converter testing function, are also on-chip.
