Dear

ansari.navid

‌,

On these STM32 series we have only Flash pages of 1Kbytes or 2 Kbytes depending on the device. You can dedicate one or two pages to emulate an EEPROM and store bytes, On the flash defaut state is 0xFF {initially erased} and when you write a data you will store 0x 0 to erased bits. For more details on advanced techniques refer to our EEPROM emulation App notes. Latest published one is on L4 series very similar.

Cheers,
