Hi, I tried to read BluePill board MCU STM32F103C8T6 flash by STM32CUBE in Target information it shows Device ID 0x410 and flash memory size 128kb but by datasheet STM32F103C8T6 flash memory must be 64 kb Why is the difference?

Old chip is damaged, one pin is broken I have resoldered new chip to old pcb, so problem can be only with new chip or firmware.

Chip is not locked, and firmware is working but partially, indicator is blinking, but MODE button do not work.

May be this is Chinese chip and marked wrongly
