We have a lineup of high-end automotive microcontrollers which are ideal for body applications and can support a wide variety of systems.

 

The RH850/F1K is one group of single-chip microcontrollers in the RH850/F1x series which is designed for automotive electrical body applications. While it achieves low power consumption, the internal flash memory ranges from 768KB to 2MB and the package covers a wide range from 100 to 176 pins. Also, a CAN FD interface has been added (premium products only) and the CPU operating frequency has been improved to 120MHz.
