what makes the TI microcontroller safer?

Hello,

   What makes the microcontroller safer? e.g if i have a herculus safety mcu and on the other hand i have a tiva c series TM4C launchpad. Can i make TM4C mcu safer like it will also have safety features like herculus?

and Safety features are from hardware level or software? or both?

    A simple question with a complex answer. In truth, it is not the microcontroller that is safe, it is a system that is safe. The Hercules family of microcontrollers add hardware features to facilitate implementation of a safe system. A safe system must be able to detect and react to a failure. For example the Hercules family uses two CPUs operating in lock step and constantly compare the output. If there is a single fault in the logic on one CPU it will be detected and the system can react. The hardware features alone don't make the system safe. If the software does not properly use those features, it will not be a safe system. Is it possible to implement a safe system with TM4C? Yes, for example you could have a system with two TM4C constantly checking each other. For more information on functional safety visit: www.ti.com/SafeTI
