what/where is USB tSTARTUP of STM32H563 ?

[mete]

The ref manual (RM0481 page 2585) says: "This circuit has a defined startup time (tSTARTUP specified in the datasheet) during which the behavior of the USB transceiver is not defined.". I searched for USB and tSTARTUP but could not find anything in the datasheet (DS14258 Rev 1). Is it missing or mentioned differently ?

Hello @mete ,

Thank you for bringing this issue to our attention.

I will check internally and I will get back to you with more details as soon as possible.

Thank you.

Hello @mete ,

The USB tSTARTUP is missing in the datasheet.

I reported this issue internally.

Internal ticket number: 165751  (This is an internal tracking number and is not accessible or usable by customers).

Thank you.

Thanks. I have seen it is written in the datasheet of STM32H503, and it is 1us. Can I assume it is going to be the same for H563 as well ?

Hello @mete ,

Yes, the STM32H563 has the same USB tSTARTUP  "1µs" as STM32H503.

Thank you for your contribution in STCommunity.
