For my design i am already using STM32F429BI--LQFP208 package, Now i am looking to replace this with STM32F777BI-LQFP208, both are pin compatible..
The above one is STM32F777BI,
The above one is STM32F429BI,
BUT in the front page of the datasheet -product description its mentioned i/o's 168 in both of the data sheet
and also in the ST.COM its mentioned i/o's 168 I/O'S
So my question is what is this difference,and what are all the 9 pins in STM32F777BI which is not GPIO..
please answer this query....
