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
temperature range (0 to 70 °C).
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
execution speed from Flash memory since the ART accelerator allows to achieve a performance equivalent to 0 wait state
program execution.
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.
