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

F71334

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

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 ?

@F71334 ,

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

Was an answer to @AScha.3  regarding the FMAC RAM size. And there is no issue in our documentations regarding Timers. As shown in the reference manual in "TIM2/TIM3/TIM4/TIM5 introduction" section, it was said "16-bit or 32-bit". So there are two 16-bit timers and two 32-bit timers as shown in Table 397.

The best answer for your request is the first one I've already provided.

Thank you.

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...
