Hi, 

We are using STM32F303 in one of our project and find the CCM routine booster is of great help. Now, we are openning a new project using F4, but the CCM programming information is very limited on F4. My questions are:

1. F405 datasheet clearly said it has CCM, will the program running in CCM still 30% faster than program running in flash?

2. Where can I find the CCM programming guide for F4?

3. Do F446 also has CCM? The datasheet didn't mention this.

Thank you!

Frank
