We will use chips with lower data witdh than 32 bits, by this we put multiple chip form the data bus.Could you help me?

Thank for your answer,We are thinking to use 2x1Gb of Microm (ref. MT25QL01GBBB8E12-0SIT). This is a TBGA24. it is not SOIC.Do you think we will have problem?

Thank you for your answer, I have addional questions:Could you say me what is the maximun number of devices SDRAM that they can connected to this interface? (1,2 or 4)Could you say me constreins and matched of these signals to access to external SDRA...

Thank you for your quiclky help, I saw this application note, but I need routing rules ( by example with is more recommended routing chain of star rouitng, maching rules between lines,...)Can you help me?Bye

Hello, I am Working with STM32H7 and I want to put in my board 2 QSPI as you put in your evaluation board stm32h745i-disco. Could you say me waht is the Interface signals layout guidelines?, by the example as router clk signal (star or daisy chain).

Hello, We are working with ref. STM32H745_755_tfbga240.ibis but when I select PF0 and PF3 signal in "available models" doesn´t appear "FMC_A0" model. I think is a mistake of STM32H745_755_tfbga240 ibis model? Could you help me Thank you in advance

Dear, We are new design of board with STM32H7 and we need to put external SDRAM using Flexible memory controller (FMC). Could you say me routing rules or routing guidelines ? Thank you in advance

What are the voltage regulator output in the reference STM32H755XIH3?
