Minimum setup for STM32H730VBT6 board

[rbairos]

Hello.
I am very new to ST electronics, though I've spent several years working with chips from another popular manufacturer.

I would like to develop a board that prioritizes multiple high-speed gpio lines.

I do NOT need:
-sdcard, usb, external flash, etc.

I do need:
-maximum number of contiguous gpio lines.
-maximum clock speed (550MHz ?)
-in-circuit programming/debugging

Am I correct in thinking the STM32H730VBT6 can be run with internal flash and data memory only?
To achieve 550Mhz would require external oscillator setup and pll?

If so, can anyone point me to the minimum board setup to achieve this?


Thank you very much!
Rob.

Doesn't need external memories or clocks.

Does need power ALL including analogue. VCAP capacitors. BOOT0 pulled down.

Debug via PA13 PA14 SWDIO/SWCLK minimum.  NRST helps. Also PB3 SWO if available for trace or SWV support.

Awesome thanks so much.
I tried browsing the docs, but wasn't quite sure. Internal oscillators are just RC based?
or can I still achieve the higher clock speeds with them?
