How much flash memory is there in the microcontroller?

I have an STM32F303CBT6 microcontroller. On the ST site, the volume of the flush is 128 kB.

enter image description here

In reference manual flash up 256 kB.

In this case, register "Flash memory size data register" contains the value 128 [kB].

There is also 128 kb in the stlink utility.

But in the cleaning window, the page costs 128 pages of 2 kB. This amounts to 256 KB.

I didn't get it. What is the size of the flash?

Solution

  • The "B" in STM32F303CBT6 stands for "128KB" (see STM32 Part Number Decoding).

    The 256KB version would be STM32F303CCT6.

    I can't tell you what the cleaning window indicates.
