Highly portable across the entire STM32 ecosystem, safe, and fast to deploy.
While the Cortex-M4 and M7 offer DSP instructions and floating-point units (FPUs), the F103 remains the go-to for cost-sensitive, power-conscious, deterministic control tasks. You will find it in: the stm32f103 arm microcontroller and embedded systems pdf
// Enable clock for GPIOC (RM0008, Section 7.3.7) RCC->APB2ENR |= (1 << 4); Highly portable across the entire STM32 ecosystem, safe,
The CPU clock is stopped, but all internal peripherals and memory domains remain active. Any peripheral interrupt can instantly wake the core. Any peripheral interrupt can instantly wake the core

To demonstrate how the hardware abstractions map to concrete code, here is an implementation of a standard blinking LED using the modern STM32Cube HAL framework. In the standard "Blue Pill" development board, an LED is hardwired to port (Port C, Pin 13).
