Refrence design for stm32f767zi

Hello I am trying to get design First pcb for stm32f7 but having a trouble understanding refrence design concept. https://www.st.com/resource/en/application_note/dm00164549-getting-started-with-stm32f7-series-mcu-hardware-development-stmicroelectronics.pdf

I searched a lot on the stm32 website and from reference manual to reference hardware manual. but i only find one figure which is mentioned in this pdf . but the problem is it is only for STM32F756NGH6 so the reference design is same for all the stm32f7 ? Will it work for stm32f767zi ? or there is another hardware manual i have to refer, if yes than please guide me through that reference manual.

You should have found it. It's under resources on the board page.

You just need to power it, all VDD/VDDA pins, and ensure BOOT0/NRST are wired correctly. Although for it to be useful, you'll need a way to program it as well, such as SWD.

The reference manual provides this information:

Doesn't Figure 6 explicitly cover the F767 supplies.

There's a F767ZI NUCLEO board design you could refer too.

Hello sir Thank you for the answer....But i could not find schematic for stm32f767zi is there any documentation i forgot to read since there are many. and f767zi nucleo board will only cover schematic for f767zi what about the f7 series which don't have nucleo board. how can one figure out that what are minimal the required components for mcu to just boot up..

Thank you for the support

Hello thank you sir,For an amazing answer. Can you please tell me which oscillator is best suitable for HSE For stm32. I have seen that it is getting clock from the stlink on the nucleoboard but i need to do it without stlink which component is best suitable for the HSE which can generate accurate results as stlink. ​

See:

https://www.st.com/resource/en/application_note/cd00221665-oscillator-design-guide-for-stm8afals-stm32-mcus-and-mpus-stmicroelectronics.pdf

Or just use one on an ST board somewhere.
