---help---
|

STM32F series parts numbering (sans the package type) ends with a number or letter

that designates the FLASH size.

This configuration option defaults to using the configuration based on that designator
|
||||
or the default smaller size if there is no last character designator is present in the
|
||||
STM32 Chip Selection.
|
||||
|
||||
Examples:
|
||||
If the STM32F407VE is chosen, the Flash configuration would be 'E', if a variant of
|
||||
the part with a 2048 KiB Flash is released in the future one could simply select
|
||||
the 'I' designator here.
|
||||
|
||||
If an STM32F42xxx or Series parts is chosen the default Flash configuration will be 'G'
|
||||
and can be set herein to 'I' to choose the larger FLASH part.
