How can i get a STM32F722xx reference schematic?

I'm trying to use the 64pin STM32F722 part for the first time this time.
I need EVM schematic and User's manual for reference circuit.
But I can't find the document.
Please tell me how I can get the documents.

(I could find the reference schematic for the BGA part of 100 pins but I need one for 64 pins.)

Where did you look?

The STM32F722RE Product Page suggests the NUCLEO-F722ZE:

You can get the schematics for that from its Product Page - on the 'CAD Resources' tab:

The NUCLEO-F722ZE has an LQFP144 part.

The number of pins is really immaterial for a reference schematic - just ignore the extras!

 

And, as @mƎALLEm already said, see AN4661.

Hello, 

You can refer to this application note: https://www.st.com/resource/en/application_note/an4661-getting-started-with-stm32f7-series-mcu-hardware-development-stmicroelectronics.pdf

there is no ref design for each package, the hw is almost the same.
