Hello, regarding the way to view batch numbers, the program can also obtain batch numbers through the DBGMCU_GetCHIPID function, where the second to last digit of the value read by this function represents the batch number.

Для F203 в примерах есть такое (получается что буквой x они обозначили номер лота.
