The RH850/F1KM-S4 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 3MB to 4MB and the package covers a wide range from 100 to 272 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. Design resources are available here to help you get your design to market as quickly as possible.
We have placed all related primary documentation on this page such as user's guides, application notes and collateral. In addition, there are links to Functional Safety and Security documentation requests which can be released under NDA.

In the Hardware Tools section, we provide links to the MCU starter kits. The starter kit is a fully self-contained hardware and software tool for evaluating microcontroller features and performance and can be used to start development. It includes the Renesas E1 on-chip debugger, access to all I/O pins and serial interfaces such as RS-232, LIN, and CAN FD. The starter kit is the fastest way to get the hardware and software needed to begin development right away. We provide links to the user's manual and software as well as a link to purchase.

In the Software Tools section, we have many resources to assist with your MCU project.
For your compiler toolchain needs, we recommend Green Hills and IAR Systems. We provide links to these partner sites which allow you to start your design without delay.
In addition, we offer libraries for programming both the code flash and data flash memories of the RH850 F1Kx microcontroller. These libraries provide an interface to the code and data flash for memory operations such as erasing, programming, blank checking, and more.
And for designs that require AUTOSAR compliance, we offer AUTOSAR 4.2.2 MCAL (Microcontroller Abstraction Layer) software. It's absolutely free of charge and offered as-is. This package contains SPAL, COM and TEST driver software.
We also offer driver generation software called Smart Configurator. It's available for free download, and it provides support in generating device drivers for peripherals such as timers, UART, A/D, and more. The software and user manuals for Smart Configurator are provided for your convenience.
