1. The number of wait states can be reduced by reducing the CPU frequency (see Figure 19).
2. If IRROFF is set to V_DD, this value can be lowered to 1.7 V when the device operates in the 0 to 70 °C temperature range.
3. Thanks to the ART accelerator and the 128-bit Flash memory, the number of wait states given here does not impact the
execution speed from Flash memory since the ART accelerator allows to achieve a performance equivalent to 0 wait state
program execution.
4. The voltage range for OTG USB FS can drop down to 2.7 V. However it is degraded between 2.7 and 3 V.
