These microcontrollers employ the RL78 core which realizes high processing performance while delivering the lowest power consumption in their class, and have an enhanced A/D conversion circuit and D/A conversion circuit.
In addition to a high-precision (±2%) on-chip oscillator enabling 32 MHz CPU operation and other standard on-chip functions from the RL78/G13, these microcontrollers have a built-in A/D conversion circuit with 12-bit precision accuracy enabling fine-grained control and support up to 8 channels of analog input and built-in D/A conversion circuit with 10-bit precision accuracy enabling fine-grained control and support up to 2 channels of analog output, allowing them to be used for a wide range of system control applications, for example sensor systems.
In addition, abundant functions for supporting functional safety, such as an A/D converter testing function, are also on-chip. With ultra-small packages such as 24-pin QFN (4 x 4 mm) and 32-pin LQFP (7 x 7 mm) ideal for compact devices, these products are suitable for devices having a sensor, such as industrial equipment, office equipment, home appliances, mobile devices, healthcare devices, and other consumer electronics.
