All-in one safety MCU for Low-end chassis system

 

The RH850/P1L-C microcontroller is suitable for low end chassis and safety systems and can support the ASIL D safety standard.

The P1L-C completes the MCU line up targeting the chassis and safety application space. First P1H-C and P1M-C were created targeting high and mid range chassis and safety systems and these achieved very high functional safety and security compliance; now P1L-C also achieves both high functional safety compliance and security for downsized chassis application with smaller feature set and small package such as 80 pin line up.

Software Design Support

Title Description
CS+ This integrated development environment (IDE) can be used for coding, assembly, compiling, and simulation.
e² studio This integrated development environment (IDE) is based on the popular combination of the open-source Eclipse IDE and its CDT plug-in that enables C/C++ language development.
E2 emulator This on-chip debugging emulator has advanced features that improve the efficiency of development. In addition to the basic functions from debugging to flash programming, this emulator supports hot plug-in and external triggers as standard items. This emulator also helps to reduce development time by downloading at high speeds (compared to the E1 emulator) and the ability to work in combination with various solutions such as the CAN communication time measurement solution by systems under development.
E1 emulator This on-chip debugging emulator is a standard model which provides basic debugging functions (production is to be discontinued at the end of December 2019).
