STM32H562 - 5V Tolerant Pins Derating Impact

[RajeshM]

Hello Community,

We are currently evaluating the STM32H562IGT6 microcontroller for our development project. During our review of the device’s pinout, we observed that several GPIO pins are designated as FT (5‑V tolerant). We would like to request clarification regarding the electrical behavior and long‑term reliability of these pins when subjected to a continuous 5 V digital input.

Specifically, we would like to understand whether applying a constant 5 V signal to the FT‑labeled pins may have any impact on product lifetime, derating considerations, or long‑term performance degradation.

The following pins are of particular interest for this inquiry:

PC0	FT_a
PC1	FT_ah
PA0	FT_at
PA6	FT_ah
PA7	FT_ah
PC4	FT_a
PC5	FT_ah
PB1	FT_ah

Thank you.

Regards,

Rajesh Matere

Hello @RajeshM and welcome to the community,

There is no impact on the product lifetime and nor degradation when continuously applying 5V to FT GPIOs.
