Working Principles

The ST72F321R6T6 microcontroller operates based on an 8-bit architecture. It executes instructions stored in its flash memory, which is non-volatile and retains the program code even when power is removed. The CPU fetches instructions from memory, performs calculations, and controls the operation of peripherals.

The microcontroller communicates with external devices through its various communication interfaces such as UART, SPI, and I2C. These interfaces enable data exchange with sensors, actuators, and other microcontrollers or systems.

The analog-to-digital converter (ADC) allows the microcontroller to convert analog signals into digital values, enabling precise measurements of physical quantities such as temperature, pressure, or voltage.

Timers/counters provide accurate timing and event counting capabilities, which are essential for tasks such as generating precise delays or measuring the duration of events.

The watchdog timer monitors the system's operation and resets it if a fault or malfunction is detected. This ensures the reliability and stability of the microcontroller-based system.
