STM32N647A0 pin mapping

[sakshi]

Hello All,

While working on a design i was stuck in a point where in i have to map PSRAM pins --> FMC_clk on a port of MCU(STM32N647A0) which is available on PC10 but it is conflicting with SPI3_SCK.Please anyone can suggest solution on this. My design required both SPI3 as well PSRAM.

Also, i tried for XSPIM_P1 Pins but in STM32N647A0 these pins are available on PO port which is not available in STM32N647A0 MCU.

Please guide in this.

Best Regards,

Sakshi

Hi,

If pin is needed, but you don't have it on this package - you have to use a bigger package with this chip.

It is easy to check it with Cube: just start a design with a package and see: will all pins be available or not. If not, change your design or try it with a bigger package.
