The RA9 family is a series of high performance MCU products for vehicles. This family integrates a high-performance microcontroller kernel with an information security kernel that supports high levels of performance. This line of products integrates multi-channel CAN, LIN and optional high speed Ethernet application network. The RA9 can support up to ASIL-B level of functional safety requirements for a variety of application scenarios such as car body control domain, entertainment domain and ADAS intelligent driving domain.

The RA9 family includes such sub-products as:

• RA9S series (single core), including: RA9S1, RA9S2 and RA9S3;

• RA9D series (dual core), which includes: RA9D1, RA9D2 and RA9D3;

• RA9T series (three cores), including: RA9T1;
