MCU Selection High Speed SPI and QSPI

Hello Team,

We are Looking to select MCU Which has High Speed SPI and QSPI in a Single Device ,

High Speed SPI - 50 Mbps to 90 Mbps ( One channel ) to interface External Ethernet Controller

QSPI - ( One channel ) - to interface with External Motion Unit

Both above interface work Independently and simultaeneously.

Device from MCU Series U5 and H5 Would be preeferable.

However , Our application is not batttery powered , so no power saving Headache.

Hello Andrew,

Thanks for Update.

From the Tools , I found Two series which matches considering M-33 Secure core. I..e STM32H5 and STM32U5.

Since , application is for industrial Automation side , Not Battery Power , So STM32H5 would be fine.

Same time, I do not Higher Speed. Of Course , Cost is matter.

Also, not sure , Whose cummunity Support is better ?

What is your suggestion on this ?
