Microchip has created IEC 61508 Safety Integrity Level 3 functional safety certification packages for two of its FPGA containing IC ranges: SmartFusion 2 and Igloo 2.

“Systems used in many high-reliability commercial aviation, space, defence, automotive and industrial applications require certification to the IEC 61508 SIL 3 functional safety specification,” according to the company.
Package deliverables include certification of Microchip’s Libero SoC design suite v11.8 service pack 4, associated development tools, and 28 of the company’s IP (intellectual property) cores, as well as safety manuals, documentation and device data sheets. Certification was through TÜV Rhineland, and a safety certificate from TÜV Rhineland is provided.
“Microchip commits to build devices used in a certified system as long as customers want to order and Microchip is able to obtain all sub-elements of a device,” according to the company. “This increases confidence that certification will not need to be repeated while also reducing the risk that a part will unexpectedly enter end-of-life and force redesign or tool flow changes.”
SmartFusion 2 devices have FPGA fabric, and Arm Cortex-M3 processor core and programmable analog circuitry, while Igloo 2 devices are general-purpose low-density FPGAs. The company claims that both use technology that is naturally resistant to ‘single-event upsets’.
