PIC16LF873-04/SP Working Principle

The PIC16LF873-04/SP is based on a Harvard architecture, meaning that it has separate code and data memory which is executed separately. The code memory is the Flash memory and data memory is the RAM. The MCU has an 8-bit bus interface that connects to all of its internal peripherals. The internal peripherals include the A/D converter, comparator, timer/counter, external interrupt, Programmable Low-Voltage Detect (PLVD), and I/O ports. The A/D converter allows the MCU to convert analog signals to digital data. The timer/counter is used to track time and generate interrupts for timing events, such as delays and pulse width modulation (PWM). The external interrupt allows the MCU to wake up from sleep mode when an external event is detected. The PLVD monitors the system voltage and will generate a reset when the voltage drops below a predefined level. Finally, the I/O ports provide a way for the MCU to communicate with external devices. The PIC16LF873-04/SP can communicate with other devices using a variety of communication protocols such as USART, SPI, I2C, and CAN.

The PIC16LF873-04/SP also includes a set of instructions that allow programs to be written to perform tasks. The instructions are divided into three groups: arithmetic and logic instructions, data transfer instructions, and branching instructions. The arithmetic and logic instructions are used to perform calculations, while the data transfer instructions are used to move data around the memory. Finally, the branching instructions are used to control the program flow. Together, this set of instructions gives the PIC16LF873-04/SP the ability to perform complex tasks.

The PIC16LF873-04/SP is an extremely versatile and powerful microcontroller, making it an ideal choice for a wide variety of embedded applications. Its efficient design and flexible hardware make it a great choice for communication systems in different fields, such as industrial automation, building automation, motor control, power systems, and medical instruments.
