What is the maximum supported rate for SPI peripherals on stm32h503rbt6u chips in slave mode?

Associate II

I use spi1 as the slave to receive data, and if the speed of the spi master is set above 11M, the data received will be misaligned.I would like to know what is the maximum speed supported by the SPI peripheral on the stm32h503rbt6u chip in the slave mode?


see, here my connection H743 to a tft display, by SPI at 48Mhz clk , no errors !

but short wires, close together and 3x ground , port speed "medium" - and no other ground to somewhere...


you have more than one ground to the boards (by usb - to pc ), this can make also problems.
