The RH850/F1KH-D8 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 6MB to 8MB and the package covers a wide range from 176 to 324 pins. Also, CAN FD and Ethernet interfaces, along with a hardware security module have been added to all products, and the CPU operating frequency has been improved to 240MHz and is equipped with a dual CPU.
