Use the RTC (Real-Time Clock) in Stop mode to wake the MCU every second for low-duty-cycle data logging.

Unlike the CISC (Complex Instruction Set Computer) architecture of older 8-bit MCUs, the Cortex-M3 uses a 32-bit RISC (Reduced Instruction Set Computer) pipeline. This allows it to execute one instruction per clock cycle in most cases. The Stm32f103 Arm Microcontroller And Embedded Systems

The system memory bootloader supports USART1, USB (DFU), CAN, and I2C – a lifesaver for firmware updates without a programmer. Use the RTC (Real-Time Clock) in Stop mode
