Working Principles

The MB90F345ASPFR-GSE1 microcontroller operates based on the Von Neumann architecture. It consists of a central processing unit (CPU), memory units, I/O ports, timers/counters, and various peripherals. The CPU fetches instructions from the flash memory, executes them, and interacts with the peripherals and I/O devices as required by the program.

The microcontroller's clock generates timing signals that synchronize the execution of instructions and the operation of peripherals. The I/O ports allow the microcontroller to communicate with external devices, while the timers/counters provide accurate timing for time-sensitive operations. The analog-to-digital converter converts analog signals from sensors into digital values for processing by the microcontroller.
