How many 32 bit timers does STM32H573 have? 2 or 4? Conflicting information in data sheet

Hello,

I'm refering to DS14121 Rev 1 of STM32H573xx. 

- "Figure 1. STM32H573xx block diagram" shows 4 32 bit timers (TIM2, TIM3, TIM4, TIM5)

- "Table 2. STM32H573xx features and peripheral counts" says there are only two.

Where can I find trustworthy information on the correct number?

Have a nice day,

F

    Yes indeed it's a typo and it will be fixed in coming revisions of the DS. Thank you for raising this up :).

    What does "typically" mean? Is there any STM32H573 that has four 32 bit timers?

    where are the missing 2 x 32 bit counters?

    tim2 + 5 are 32 bit:

    tim 3 + 4 are 16 bit:

    and where the other 32 bit counters ?

    OK. Now it's clear. It  will be fixed in coming revisions of the DS. It will be treated in the same ticket number: 168793.

    It is literally the first issue reported in the second sentence of the head post. But, of course, who could notice such a "hidden" text...
