Vhys parameters for STM32F2xxx MCU I/O ports

What is the correct Vhys parameters for STM32F2xxx MCU I/O ports?

It looks like as wrong datasheet values here (DS6329 Rev 18):

https://www.st.com/resource/en/datasheet/stm32f207vg.pdf#page=102

0693W00000Suc2xQAB.pngThe published values are too big.

Please double check the chapter Table 46. I/O static characteristics for valid parameters and give me feedback asap.

Thank you in advance.

The 100V for sure

​

The 45%VDD + 0.3V perhaps less so
