STM32N6 Datasheet Feature Summary - inaccurate

Hello ST,

The STM32N6 Datasheet (DS14791 Rev 2) claims that the device has 1 HR Timer and 4x 32-bit General Purpose Timers, yet the Functional Overview section does not support these claims.  Nor does the Reference Manual (RM0486 Rev 1).  Could you please cdis-ambiguate for us, and mark the incorrect documentation for revision?

Also, is it really true that the DP-FPU capability is not present:-(

Thank you!

Regards,

Dave

Plus:

  • Only 10 GP timers;
  • Those claims should be prefixed with, "up to...".
