Robust and Flexible Functional Safety System Basis Chips

DETROIT, Michigan – October 5, 2016 – (NXP FTF Connects Forum-Detroit) – NXP Semiconductors introduces its latest generation of system basis chips (SBCs) with the new FS45 and FS65 products, engineered to support the creation of robust, system-level functional safety systems, while helping reduce overall energy consumption.


The new SBCs target automotive applications such as battery management systems, electric power steering, electric or hybrid electric vehicles and advanced power train systems such as start & stop, or transmission control. Both feature "Fail silent" functionality that helps to ensure predictive reaction after failure, as well as configurable device behavior that can be adapted by software designers to specific system safety goals. A configurable fail silent strategy supports a variety of system safety concepts and levels up to ISO 26262 Automotive Safety Integrity Level (ASIL) D.


The new FS45 and FS65 products are NXP's follow-on offerings to the popular MC33907/8 SBCs, which successfully completed TUV SUD functional safety assessment in 2015. The new devices offer optimized efficiency, scalability and reliability, and have successfully demonstrated high quality during qualification, doubling reliability performance compared to standard Automotive qualifications requirements from AEC Q100.


All NXP SBCs undergo stringent, automotive-grade safety critical processes and tests, including fault injection testing at silicon level, and more than 350 battery pulses applied to the product, validating system robustness for availability under a wide range of challenging supply voltage profiles.


Key features include:

NXP's new FS45 and FS65 chips feature

  • Flexibility – configurable fail silent strategy for car electrification (availability versus safety).
  • Scalability – supports 32-bit MCUs with dual DC/DC from 0.3 A up to 2.2 A and offers system scalability across the physical layer, the fail-safe output and the long duration timer.
  • Efficiency – ultra low-power modes, down to 30 μA with long duration timer for parking mode to save battery discharge.



FS45 and FS65 portfolio chips are automotive-qualified and now available.
