the Flash of STM32F100C8T6 is 64K or 128K ?

[cTomm]

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?

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

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.
