RL78/F15 automotive microcontrollers employ the RL78 core, which realizes high processing performance while delivering the lowest power consumption in its class. A high-speed on-chip oscillator provides 32MHz CPU operation. An enhanced motor control functionality is offered by the motor control timer (Timer RD). For easy migration RL78/F15 is pin- and software upwards compatible to RL78/F14. The RL78/F15 Group even supports 125 ℃ (target) operation, whereby a CPU clock of 24 MHz can be reached. In addition, an abundance of functions to support functional safety, like ECC on RAM and a stack pointer monitor as well as an A/D converter testing function are available. With packages from 48 to 144-pin, a memory range from 128KB to 512KB flash, and advanced IPs for LIN and 2 channels of CAN communication and IEBus, these products are very well suited for a broad range of cost-sensitive automotive applications like DC- and BLDC motor control, HVAC, lighting and many kinds of body ECUs.

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.
