Renesas RH850F1KM series microcontroller is based on the RH850G3KH core and designed for automotive electrical body applications. It achieves low power consumption with an internal flash memory range of 512KB to 1MB. In addition,the CAN FD interface has been added,and the CPU frequency is up to 120MHz. Renesas RH850F1KM series microcontrollers offer high safety and support for ISO26262 ASIL-D functional safety level applications.

As an important global partner of Renesas Semiconductor, Shanghai ZC provides a basic software platform for the RH850F1KM series of microcontrollers. Mainly includes: muti-core operating system, communication protocol stack (CAN/LIN), diagnostic protocol stack (UDS/J1939), network management (OSEK/AUTOSAR), calibration protocol stack (XCP/CCP), storage protocol stack, complex driver modules, etc., along with ZC's bootloader refresh program and upper machine tool, which can be configured and redeveloped according to different customer project requirements. While providing basic software products, ZC also offers development services for the implementation of control unit basic software functions.

ZC.MuNiu basic software platform for RH850F1KM

ZC.MuNiu Basic Software Platform can be applied to the development of automotive electronic control unit products using the Renesas RH850F1KM series chips. For example:

ØEngine Controller

ØSteer Controller

ØIntelligent Driving Controller

The AUTOSAR organization was established in 2003, mainly by European car manufacturers, component suppliers, and other electronics, semiconductor, and software system companies. It is committed to developing an open, standardized software architecture for the automotive industry. The goal is to "cooperate on standards and compete on applications", so can improve the stability of the basic platform, reducing costs, and enhancing the quality and speed of controller product development. The 2.1 version of the specification was released at the end of 2006, and the 3.1 version was released in 2008. Functional safety, Ethernet, and other contents are also added. Currently, the widely used versions are 4.2.1 and 4.2.2, as well as version 4.3.1.

In the major trends of electrification, connectivity, and intelligence, the number of automotive electronic and electrical components is increasing. The electrical structure is becoming more complex, and the development cycle of the vehicle is continuously shortening. Basic software plays an increasingly important role.

ZC provides development services comply with ASPICE Level 3 processes and functional safety requirements of ASIL-D. ZC also provides customized complex driver software for SBC (Safety Control Board) chips and BCCIC (Battery Cell Control IC) chips. By integrating ZC's functional safety product SafetyFrame, the requirements for functional safety can be satisfied.

ZC has the core technology of the AUTOSAR basic software and can provide on-site support with high quality, fast speed, and low cost.

Functional Safety

The MuNiu Functional Safety Platform provides development services compliant with ASPICE Level 3 process and ASIL-D functional safety requirements, implemented in accordance with ISO 26262 standard. Through the integration of multiple safety-related modules, the MuNiu platform offers comprehensive functional safety solutions:

Ø  Watchdog Management: Implements monitoring of system-critical tasks through WdgIf (Watchdog Interface) and WdgM (Watchdog Manager), supporting both internal and external watchdogs to ensure real-time monitoring of system operational status.

Ø  End-to-End Protection: Implements E2E communication protection mechanisms, ensuring data integrity and correctness during transmission through CRC verification, counters, and timestamps.

Ø  Memory Protection: Implements CRC verification and data redundancy backup for critical data through storage management modules including EA (EEPROM Abstraction), FEE (Flash EEPROM Emulation), and NVM (Non-Volatile Memory Manager), ensuring storage reliability.

Ø  OS SC4: Implements AUTOSAR OS with Scalability Class 4 (SC4) features, providing memory protection mechanisms, timing protection monitoring, and service protection for safety-critical applications.

ZC.MUNIU BASIC SOFTWARE PLATFORM ARCHITECTURE

To meet the diverse project requirements of customers and enhance the scalability of the basic software platform, the MuNiu basic software platform has implemented the configurability of each module and has also developed a configuration tool. Customers can complete the configuration of each module according to different needs on the configuration tool, generate configuration code files, and integrate the generated configuration files into the project.

ZC.MuNiu basic software platform configuration tool is based on the Eclipse platform and is built on the ARTOP architecture, which implements the parsing of the AUTOSAR model and ARXML. In addition to the modules defined by the AUTOSAR standard, it also supports OEM and Tie1 manufacturers to develop their own modules for secondary development. After the configuration is completed, the configuration code for each module can be generated.
