RL78/F13 microcontrollers are successors to the 78K0R and R8C, are available in a 20 to 80-pin, 16KB to 128KB 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 in addition to the functional safety features, a RAM ECC function, PLL lock function, port output state monitoring, stack overflow detection, dedicated WDT oscillator and more have also been added. Since a more highly reliable system can be built, these microcontrollers can be used for industrial applications and of course automotive applications.
