← TechnologyWhich risk increases when a microcontroller's clock frequency exceeds its maximum rated value?
A)Setup and hold time violations✓
B)Electromigration induced open circuits
C)Increased impedance matching quality
D)Reduced metastability in flip-flops
💡 Explanation
Setup and hold time violations increase because exceeding the clock frequency pushes the propagation delays above the rated values, generating race conditions. Therefore timing problems arise, rather than metal migration which is about current density.
