Working Principles

The EGLXT973QEA3V-873108 microcontroller operates based on the principles of digital logic and integrated circuit technology. It consists of a central processing unit (CPU), memory units (flash memory and RAM), input/output ports (GPIO), communication interfaces (SPI, I2C, UART), and analog-to-digital converter (ADC) and pulse width modulation (PWM) modules. The CPU executes instructions stored in the flash memory, processes data from various sources, and controls the operation of connected devices through the GPIO pins and communication interfaces.
