Measured at supply pins, including peripherals, ARM, and L2 cache supplies (QVCC, QVCC1, QVCC4, respectively).
Min voltage listed is for the lower frequency. See
Core voltage supply is considered “Overdrive” for 1.45–1.65 V range. Duty cycles in core overdrive—whether switching or
not—must be limited to a cumulative duration of 1.25 years or less (25% duty cycle for a 5-year rated part) to sustain a
maximum core VDD operating voltage of 1.65 V without significant device degradation.
The SR voltage (Quiet supplies QVCC, QVCC1, QVCC4), is applied after IC is put in SR mode. NOTE: Applying low voltage
point is dependent on noisy (NVCC) supplies being less than or equal to 1.95 V.
The range—1.9 V to 2.7 V—is a valid voltage range; however, the voltage ranges given in this table align to more common
industry voltage ranges.
