Description
RL78/F14 microcontrollers are positioned as the upper-level product of the RL78 series, 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/F14'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.
