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.

Title Description
e² studio This integrated development environment (IDE) is based on the popular combination of the open-source Eclipse IDE and its CDT plug-in that enables C/C++ language development.
CS+ This integrated development environment (IDE) can be used for coding, assembly, compiling, and simulation. CS+ is also included with starter kits.
E2 emulator Lite This entry-level on-chip debugging emulator provides functionality equivalent to that of the E1 emulator at a low price.
E2 emulator This on-chip debugging emulator has advanced features that improve the efficiency of development. In addition to the basic functions from debugging to flash programming, this emulator supports hot plug-in and external triggers as standard items. This emulator also helps to reduce development time by downloading at high speeds (compared to the E1 emulator) and the ability to work in combination with various solutions such as the tuning of current drawn by systems under development.
E1 emulator This on-chip debugging emulator is a standard model which provides basic debugging functions (production is to be discontinued at the end of December 2019).
