The successors to the 78K0R and R8C, with the industry's lowest level of consumption current. Due to high reliability and built-in motor control functions, these automotive general-purpose low-end microcontrollers can be used not only for automotive applications but also industrial applications.


RL78/F14 microcontrollers are positioned as the upper level product to the RL78/F13, are available in a 30 to 100-pin, 48 to 256 KB flash memory lineup, and realize the industry's lowest level of consumption current. They have a built-in CAN module and LIN module for automotive interfaces, and also support BLDC motor control using the RL78/F13's functional safety features, timer RD, comparator, and D/A converter. Since a highly reliable system can be built, these microcontrollers can be used for industrial applications and of course automotive applications.
