Frequently asked questions
What does 120MHz on a Cortex-M4 with an FPU mean for a real-time control design?
The 120MHz clock rate combined with the on-chip FPU removes the software floating-point penalty that Cortex-M0/M0+ cores pay for PID loops, digital filters, or sensor-fusion math — cycle-count budgets that would consume 40–60% of a 72MHz M0 core run at a fraction of that on this part at 120MHz with the FPU engaged.
