Working Principle

The basic operating principle of the STM065B44Q is quite similar to that of any other microcontroller. It consists of an 8-bit CPU, memory, and peripherals, along with a 16-bit timer, a 32-bit hardware monitor, and an external quartz oscillator. The system is powered by a voltage source, which can range from 3.3V to 5V. The voltage is then regulated by internal circuitry to the necessary value for operation.

The CPU is responsible for processing instructions and data stored in memory. The 16-bit timer is used to time-based operations and accurate clock counting. The integrated Hardware Monitor checks system states and performance, providing data to adjust settings accordingly. The external quartz oscillator provides a very accurate clock signal for control over timing aspects such as system responsiveness.
