Working Principle

The AT89C51RC-24PU microcontroller works in three main stages. These are the reset, run, and interrupt stages. During the reset stage, the microcontroller is initialized and the instruction set is loaded into the program memory. The second stage is the Run stage, in which the microcontroller is programmed to execute the instructions. The interrupt stage is the third stage and is the most important stage. In this stage, the microcontroller responds to the external interrupts by suspending the current execution of the program and transferring the control to the address stored in the interrupt vector register.

Once the interrupt has been serviced, the microcontroller returns to the program execution. The AT89C51RC-24PU also has an on-chip clock generator, which allows the microcontroller to run real-time applications without the need of an external clock. The microcontroller will continue to run until the power is removed or the reset button is pressed. The microcontroller also has a programmable watchdog timer, which helps to protect against system crash caused by software and hardware malfunction.

The AT89C51RC-24PU microcontroller is a powerful and cost-effective solution for many embedded applications. It provides excellent performance, low power consumption and high reliability. The device is easy to program and is suitable for low-cost and low-power applications.
