I have a product that needs to write parameters to Flash.

I saw on the website and datasheet all tell me STM32F100C8T6 is 64K Flash,

Flash 1K per page, total 64 page,the finnal page is page 63,however I made a fault I made a fault I write parameters to Flash of page 127,I found that 127 pages of Flash can save and store data.

Does this mean that Flash has 128k can be program?

Hi @cTomm​ ,

The STM32F100C8T6 has a 64 Kbytes of Flash memory as indicated on the datasheet and all access outside of this memory area is considered as "Out of specification": ST does not guarantee the flash behavior outside of the region specified in DS.

Depends on the die used, there should be a 16-bit word value in OTP describing the size in KB that was tested. ​
