Power 5V display and use FSMC pins

JBond.1 · ‎2020-05-19

Hi, I have STM32F407VE and this display which require 5V power:

Is it ok, to connect it to 5V and to FSMC pins? I wont demage FSMC pins?

The power supply on the STM32F4 chip must be 3.3V or lower. It looks like the signals for that display have level shifters on the lines, in which case connecting it to the FSMC pins might be okay. Check the device datasheet.
