Enhanced Embedded Flash Controller
Flash Speed
Refer to
Figure 8-3.
Erasing the memory can be performed as follows:
The Enhanced Embedded Flash Controller manages accesses performed by the masters of the
system. It enables reading the Flash and writing the write buffer. It also contains a User Inter-
face, mapped on the APB.
The Enhanced Embedded Flash Controller ensures the interface of the Flash block.
It manages the programming, erasing, locking and unlocking sequences of the Flash using a full
set of commands.
One of the commands returns the embedded Flash descriptor definition that informs the system
about the Flash organization, thus making the software generic.
The user needs to set the number of wait states depending on the frequency used:
For more details, refer to the “AC Characteristics” sub-section of the product “Electrical
Characteristics”.
