The STM32F103 family is categorized based on flash memory size and pin counts into low-density, medium-density, and high-density devices. The most ubiquitous variant, the , falls into the medium-density category and boasts: 64 KB to 128 KB of Flash memory (for program storage). 20 KB of SRAM (for runtime variables and stack operations).
Embedded systems rely heavily on robust data-sharing protocols. The STM32F103 natively supports: the stm32f103 arm microcontroller and embedded systems pdf
Active transistors pull the output directly to high (3.3V) or low (0V) levels, capable of sourcing or sinking up to 25mA. The STM32F103 family is categorized based on flash
