STM32H753 SPI data rate

[tariq]

Hello. Is the STM32H753 able to directly interface with a slave on the SPI bus, which continuously produces data at a rate of 40 Mbps for several hours? What would be the current consumption rate for such a case?

Thank you

Hi,

the 40M speed is no problem, see ds :

100M max , slave or master.

Same as if not use SPI , almost. You can check it in Cube -> Tools ...power consumption.

So this might be a problem : what you wanna do with these 50 GB on a cpu with 1MB RAM ??
