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.
