Introduction of System Basis Chip (SBC) FS45 and FS65 Series

NXP Semiconductors has newly introduced the FS45 and FS65 series, the latest system basis chips (SBC). These products provide functional safety with high system-level reliability while simultaneously reducing overall power consumption.

The newly introduced SBC products can be used in battery management systems, electronic steering systems, electric vehicles or hybrid vehicles, as well as advanced power train systems such as start/stop devices and transmission systems.

Both products feature a "Fail Silent" function, enabling predictable response even in the event of a fault, and can be configured during software development to meet the safety objectives of specific systems. With configurable fault handling functionality, they can address diverse system safety concepts and meet the criteria of ISO 26262 Automotive Safety Integrity Level (ASIL) Grade D.

The newly introduced FS45 and FS65 products are successors to NXP's MC33907/8 SBC. The predecessor successfully passed TÜV SÜD functional safety assessment in 2015. The new products have undergone optimization for efficiency, scalability, and reliability, and demonstrated superior performance during approval testing, achieving twice the reliability standards required by the AEC Q100 automotive standard.

All of NXP's SBC products undergo rigorous automotive mandatory safety processes and testing. These processes include defect elimination testing at the semiconductor level. Additionally, products are subjected to over 350 battery pulses to verify performance that maintains system reliability despite a wide range of challenging supply voltage characteristics.
