Can anyone explain this footer note in the electirical characteristics sheet for the STM32F777xx STM32F778Ax
STM32F779xx. on page 110.

2. 216 MHz maximum frequency for 6 suffix version (200 MHz maximum frequency for 7 suffix version).

 

I am using the STM32F779NI. Is the suffix 7 or 9? I dont see it specificed anywhere.

 

Thanks!

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

In addition to the note from @Andrew Neil , there is also the information that usually not all theoretically possible combinations of the Ordering Information can be ordered. The STM32F779NI is currently only available in the Industrial Temperature version, which is identified by the order suffix 6.
