1. The number of wait states can be reduced by reducing the CPU frequency.
2. If an inverted reset signal is applied to PDR_ON, this value can be lowered to 1.7 V when the device operates in a reduced
3. Prefetch is not available. Refer to AN3430 application note for details on how to adjust performance and power.
4. Thanks to the ART accelerator and the 128-bit Flash memory, the number of wait states given here does not impact the
5. The voltage range for OTG USB FS can drop down to 2.7 V. However it is degraded between 2.7 and 3 V.
