RH850/F1KH-D8

Description

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.

How to use IAR Systems compiler in e² studio
PDF 666 KB R20AN0733EJ0200 Rev.2.00 日本語 Sep 13, 2024
AI-generated Summary: The document explains how to integrate and use IAR Systems compilers within the e² studio development environment for Renesas microcontrollers. It details the installation of IAR Embedded Workbench and IAR Eclipse plugins, project creation, build configuration, and build execution using IAR compilers. The guide focuses on the RA family with the IAR ARM compiler but applies similarly to other Renesas devices. It also recommends using standalone Flexible Software Package configurators for RA and RZ families to enhance development. The environment setup assumes Windows 10 64-bit, e² studio 2024-07, and IAR tools installed.

RH850 Family SENT Emulation Application Note
PDF 907 KB R01AN7195ED0100 Rev.1.00 Dec 05, 2023
AI-generated Summary: The document explains how to emulate a SENT transmitter to interface with RSENT receiver modules in Renesas RH850 MCUs. SENT (Single Edge Nibble Transmission) is a unidirectional protocol transmitting sensor data to engine control units, offering a low-cost alternative to CAN or LIN. It details SENT’s fast and slow channel message structures, including synchronization pulses, data nibble encoding, and CRC checks. The document covers the RH850/F1KM-S1 MCU and related families with Timer Array Unit D (TAUD), providing essential information for developing SENT-based software without requiring physical SENT sensors or PCB designs.

GreenPAK Configuration and Programming with RH850
PDF 1.29 MB R00ZZ0017EE0100 Rev.1.00 Oct 11, 2023
AI-generated Summary: GreenPAK devices integrate cost-effective, non-volatile memory programmable logic with RH850 32-bit automotive microcontrollers via I2C communication. The SLG46827-A model offers 2,048 bits of non-volatile configuration memory and volatile RAM, enabling flexible reconfiguration of macrocells and IOs. The I2C interface supports various commands for reading, writing, erasing, and protecting memory areas. RH850 devices with RIIC interfaces manage communication and control, allowing remote programming and real-time monitoring of GreenPAK configurations. The document details command structures, device addressing, memory protection, and hardware/software tools required for development and debugging.
