Maximum TRACECLK frequency of STM32H725

[BGo]

Hello,

I have not found the maximum TRACECLK frequency of the STM32H725 in the documentation. It looks like it is generated by PLL1 with flexible division ratios and thus can attain values that are not realistic for I/Os (100 to 220 MHz for Speed 11 and 2.7 V ≤ VDD ≤ 3.6 V as per p.165 of DS13311).

Is the maximum TRACECLK set by the maximum I/O output frequency or is it restricted to another value?

Regards,
Bernd

Hello @BGo and welcome to the ST community,

You can reach 170MHz with the IO when HSLV is ON / Speed = 11.

DS13311 Rev 5 / Table 59:

" as per p.165 of DS13311" is for HSLV OFF
