I can't find the page size of STM32401RE nucleo flash memory in the reference manual. Does anyone have the information?

Thanks

The Nucleo board has no FLASH external to the 'F401, so you probably meant the internal FLASH in the 'F401.

Its page (here called "sector") size is varying, as the Reference Manual describes:

You will not find this information in the documentation for the NUCLEO, but in that of the target MCU, in this case the STM32F401RE. Specifically, the sectoring of the flash can be found in RM0368, section 3.3.

Hello @HABIJ.1 

for the STM32F401 the flash is organized on sectors and not pages.  For more details, refer to the table 5 of the  RM0368 rev5.
