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. Design resources are available here to help you get your design to market as quickly as possible.

Hardware Tools
In the Hardware Tools section, we provide links to the MCU starter kits. The starter kit is a fully self-contained hardware and software tool for evaluating microcontroller features and performance and can be used to start development. It includes the Renesas E1 on-chip debugger, access to all I/O pins and serial interfaces such as RS-232, LIN, and CAN. The starter kit is the fastest way to get the hardware and software needed to begin development right away. We provide links to the user's manual and quick start guide as well as a link to purchase.

Software Libraries
The Flash Libraries are provided to easily rewrite the RL78 code and the data flash memory. The Flash Self-programming Library (FSL) can be used to rewrite the code flash. The Data Flash Access Library (FDL) allows simple access to the data flash. By the use of the EEPROM Emulation Library (EEL) the data flash performs in an EEPROM-like manner. The EEL also contains the FDL.
