1 / 422 page  R01DS0442EJ0100 Rev.1.00 Page 1 of 422 Sep 15, 2023 Section 1A Overview of RH850/F1KH-D8 1A.1 RH850/F1KH Outline This RH850/F1KH-D8 is a 32-bit single-chip microcontroller with dual core CPUs, Code Flash, Data Flash, RAM modules, DMA controllers, A/D converters, timer units and many communication interfaces that are used in the automotive applications. This microcontroller has been developed as a Safety Element out of Context (SEooC) in accordance with ISO26262. RH850/F1KH-D8 main features are as follows: (1) RH850 dual core CPU This microcontroller contains dual RH850G3KH2.0 cores support RISC-type instruction sets and have significantly improved the instruction execution speed with basic instructions (one clock cycle per instruction) and the optimized 5- stage pipeline configurations. Furthermore, this product also supports bit manipulation instructions as instructions best suited for various fields. Two-byte basic instructions and high-level language instructions improve object code efficiency for the C compiler and reduce the program size. Furthermore, this product is suited for advanced real-time control applications by offering a high-speed response time including the processing time of the on-chip interrupt controller. (2) On-Chip Code Flash and Data Flash This microcontroller has high-speed Code Flash from which CPU can fetch the instructions and the constant data. Code Flash with a capacity of up to 8 MB can be reprogrammed when the chip is implemented in the application system. This chip also has Data Flash with a capacity of 256 KB. (3) Rich peripheral functionality This microcontroller supports common communication interfaces such as CSI as well as automotive-oriented communication interfaces such as Ethernet, FlexRay, CAN-FD, LIN and SENT. As internal peripheral modules, this microcontroller incorporates A/D Converter and Timer module. (4) Low power consumption This microcontroller provides some function for low power consumption. Low Power Sampler (LPS) polls signal inputs without CPU core interaction. DeepSTOP mode disables power to select circuits within the chip. (5) Functional Safety support This microcontroller includes several dedicated functionalities such as the memory protection with ECC on data and clock monitors to support the functional safety standard (ISO26262) required in the automotive applications.
