Hello All,
I need to design a board that will carry an IS42S32400F-6BL SRAM ,STM32H750XB MCU,Flash MT25QL512ABB1EW9-0SIT and Couple of support components along with Power supply.
My questions-
1) MCU Power Supply Protection
2) High frequency filter placements (ferrite beads)
3)SPI /I2C Pin protection
4) Analog and Digital Layers placement
5) Optimal PCB Layer to be used
6)PCB Stack consideration

Hello @Caan
For some design tips on how to set your design using the STM32H750xB value line, you may want to start by refering to the Getting started with STM32H74xI/G and STM32H75xI/G MCU hardware development application note (AN4938). Also, you can refer to the design of the STM32H750B-DK since this board is based on the same MCU you will be using.
For a dedicated HW support, you may want to contact an HW expert to review your design and give you more advices dedicated for your case.
Best Regards.

Hello @Caan ,
There are no resistors between SDRAM data lines and the MCU. Only unused data lines are pulled low via pull down resistors:
This is because the SDRAM is used only in 16bit data width so the rest of the data lines D16 to D31 are unused.
