Footprint and Symbol STM32N657B0H3Q & STM32647A0

[sakshi]

I was using the CAD resources files from ST for the symbol & footprints of STM32N657B0H3Q & STM32647A0 but could find some pins missing in symbols and footprints as given in the discovery kit. So can anyone check and guide on this..I'm attaching the screen shots of symbols from the discovery kit and the symbol downloaded from the CAD resources.

The symbol downloaded from the ST CAD resource for STM32N657B0H3Q (For instance PB1, PB2... pins are missing,) similar is the case for the STM32647A0 CAD files from ST CAD resource.

The below attached screenshot is of STM32N657B0H3Q discovery kit having all pins of MCU.

Hello @sakshi 

The STM32N6570-DK embed STM32N657X0H3Q. Which is VFBGA264 package.

The STM32N657B0 is VFBGA198 and STM32N657A0 is VFBGA169.   
They do not have the same number of GPIOs available compared to the VFBGA264. Refer to DS14791 Rev 3 Table 18. Pin description for all the details.

Note: PA4, PB1, PB2, PB8.... are only available on STM32N657L0 VFBGA223 and STM32N657X0 VFBGA264.
