Electrical characteristics
Table 46.
1. Based on characterization data, not tested in production.
2. The I/O speed is configured using the OSPEEDRy[1:0] bits. Refer to the STM32F20/21xxx reference manual for a
3. TBD stands for “to be defined”.
4. The maximum frequency is defined in
5. For maximum frequencies above 50 MHz, the compensation cell should be used.
