STM32F103C8T6 flash

STM32F103C8T6 is a microcontroller from STMicroelectronics based on the ARM Cortex-M3 core. It has 64KB flash memory that can be programmed and reprogrammed in-system, which means that you can write and update the program code while the microcontroller is still connected to the circuit. The flash memory is divided into sectors, with each sector being 2KB in size. The microcontroller uses the flash memory to store the firmware code, which is executed when the device is powered on. It is also used to store data that needs to be retained even when the power is turned off, such as configuration settings or user data. The flash memory can be programmed using a JTAG or SWD interface, and programming can be done using various software tools such as ST-LINK, Keil, or IAR.
