OCTA SPI PINs For STM32U575VIT6Q Controllers

[HA2375-]

Hi @Issamos 

Hope You doing well .

 we are started new design using STM32U575VIT6Q this controller, we have some doubts regarding the SPI line, we searched in the STM32cubemx in that we cannot able to find the octa spi pins, Can you pls share me the Standard SPI lines pins and Octa SPI pins ,

thanks

@Issamos waiting for your replay

thanks.

Hello @HA2375- 

Please refer to the product's STM32U575 datasheet in table 27 to be able to identify the pins assignment (for exact free/usable pins)

• SPI2_NSS: PD0, PI0..
• SPI2_SCK: PD1, PD3, PI1..
• SPI2_MISO: PD3, PI2..
• SPI2_MOSI: PD4..
• SPI3_NSS: PG12
• SPI3_SCK: PG9
• SPI3_MISO: PG10
• SPI3_MOSI: PG11
• ...

There are multiple SPI and OctoSPI pin options, with assignments and you can use STM32CubeMX to configure and remap the alternate functions as needed:
