Embedded - Microcontrollers

The PIC18F23K20T-I/SS microcontroller is a compact, low-power and high-performance integrated device. It has an advanced architecture and enhanced I/O capabilities, making it ideal for a wide range of embedded applications. This article will discuss the application fields where this microcontroller can be used, as well as its working principle.

Working Principle

The basic architecture of the PIC18F23K20T-I/SS microcontroller consists of an internal memory, a CPU, I/O peripherals, an internal oscillator and an A/D converter. The internal memory is composed of RAM, ROM, EEPROM and Flash memory, allowing it to retain data and program code even when the power is off.

The CPU manages the internal and external peripherals, such as the I/O ports, A/D converter, timer, serial ports and interrupts. The I/O ports allow the microcontroller to interact with external devices such as sensors, relays, switches and LCD and LED displays. The timer can be used to generate periodic interrupts, which helps to schedule tasks within the system.

The internal oscillator provides the clock signals that the microcontroller needs to process its instructions. The A/D converter is used for analog to digital conversion, which is essential for applications such as data acquisition or control of actuators.
