Can a voltage be applied to pin PC4 on the LSM32L476 chip

[KnarfB]

PC4 is a normal IO pin, not for power supply. If the chip is powered, and PC4 is configured as input, it will accept logic levels. For detailed electrical characteristics see STM32L476xx data sheet.

KnarfB, I did not ask the correct question. I have a mb1136 c-04 218430905 board with the L476 chip loaded and pin OC4 is initialized to read ADC input. I need to kno if there is a way to connect my voltage generator to the PC4 pin on the board to test my analog procssing. A schematic of the board would help. I there a User Guide?

[KnarfB]

Yes, UM1724 User manual STM32 Nucleo-64 boards (MB1136).

Schematics online: https://www.st.com/en/evaluation-tools/nucleo-l476rg.html#cad-resources

Ther AVDD and AGND pins are perfect to suppy test input, preferrably using a ~1k serial resistor.

Thanks. That is what I needed. Happy New Year
