This white paper provides a detailed look at the SmartFusion2 SoC FPGA family and demonstrates the dramatic advantages SmartFusion2 SoC FPGAs make available to designers of advanced security, high reliability, and low power systems. Advanced security applications can count on the SmartFusion2 family to deliver unmatched design security, design protection and security key protection while employing the most advanced techniques for protecting application-level cryptographic keys from external attacks. The flash fabric coupled with SEU immune memory implementations produces the lowest FIT rate in the industry making SmartFusion2 devices a smart solution for high-reliability applications.
