Automotive Microcontrollers for the Space Industry

Renesas' proven in-vehicle microcontrollers can be used in application fields that require higher performance and higher reliability, such as aircraft. Renesas' high-reliability microcontrollers R5F72544RKBGV#US and R5F72533KFPU#US have been developed in the automotive industry and applied to the aerospace field. Note, however, that these products are designed without consideration for space radiation. The product does not guarantee radiation resistance. We request the customers perform the radiation test before using the product.
