SPI interface characteristics

[giwonKIM]

Hi.

 

I am selecting for chip upgrade.

In the database content of STM32H743ZG, the SPI interface characteristics section says that the VOS level should be set to VOS1 as shown in the picture, but I chose rev.V to use the main frequency 480 MHz.

So my VOS level is estimated to be VOS0.

can't I use spi properly?

 

Or, It means that VOS level is changed from VOS0 to VOS1?

Sorry for not speaking English well.

If you have any questions, please ask me.

Additinal, is there a lot of difference between rev.Y and rev.V other than the max main frequency?

Thank you.

Just buy rev. V if you can, and don't worry about rev. Y. The latter is obsolete, you just don't want it.

The quoted text does NOT mean that VOS1 must be used with SPI. It only describes condition of some test or measurement. You can of course use SPI at VOS0 and max. system clock. Select the SPI clock prescaler as needed for your SPI device.
