Notes

PC0-NRST (Pin 1): Configurable as either PC0 or NRST/SWDIO via option bytes. When configured as NRST, it serves as the reset pin with internal pull-up.
PB6-SWDIO (Pin 5) and PA2-SWCLK (Pin 15): After reset, these pins are configured as SWDIO and SWCLK alternate functions (with internal pull-up and pull-down resistors respectively) depending on option byte configuration.
PA7 (Pin 20): Includes MCO and SWDIO multiplexing options.
All I/O ports are 5V-tolerant (COM type).

Absolute Maximum Ratings

If the applied voltage exceeds the absolute maximum value given in the table below, it may cause permanent damage to the chip. Only the strength ratings that can be tolerated are listed here, and it does not imply that the functional operation of the device is correct under these conditions. Operating under maximum conditions for a long time may affect the reliability of the chip.
