RL78/F14 microcontrollers are positioned as the upper level product to the RL78/F13, are available in a 30 to 100-pin, 48 to 256KB 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 and automotive applications.
