In consumer products, the microcontroller can be used to control home appliances and electronic devices like TVs and home theaters, remotely operated through a phone app.

Working Principle

The PIC16C716-20/SO is based on the PIC architecture, which enables the microcontroller to execute code sequentially and execute multiple asynchronous operations in the background. The microcontroller has a 16-bit instruction set, which provides support for arithmetic and logic operations, data movement and storage, program execution and interrupt handling, and communication with input and output devices. The instruction set architecture and instruction set are key components that govern the device\'s working principle and determine the operations that can be performed by the microcontroller.

Central Processing Unit (CPU)

At the core of the PIC16C716-20/SO is the Central Processing Unit (CPU), which controls the execution of instructions, performs arithmetic and logic operations, and controls the flow of data. The CPU is composed of two main components: the Arithmetic Logic Unit (ALU), which performs arithmetic and logic operations, and the Control Unit (CU), which stores and interprets the program itself, controls the flow of data, and manages interrupts and other external events. The PIC16C716-20/SO also features an on-chip oscillator, which is used to generate the internal clock signal required by the microcontroller to run its operations. The clock is generated by the oscillator and fed to the CPU, which can then use it to keep track of the program\'s progress and execute instructions at a specific frequency.

Memory

The PIC16C716-20/SO has 2KB of internal Flash memory, which is used to store the program instructions, data, and other information required for the microcontroller\'s operation. The program instructions are stored in the Flash memory address space, which is mapped to a register within the CPU. When an instruction is required by the CPU, the address of the instruction is obtained from the register and the instruction is retrieved from the Flash memory. In addition to the Flash memory, the PIC16C716-20/SO also contains 6KB of SRAM, which can be used to store program variables, data, and other temporary values.

Input/Output Ports

The PIC16C716-20/SO microcontroller also contains 16 I/O ports, which can be used to interface with external devices. Each I/O port is associated with a data register, which is used to store the current state of the I/O line. The data registers can be written to and read from, allowing the microcontroller to control the state of an external device. Output ports can be used to control the output of a device, while input ports can be used to read the state of a device. The I/O ports of the PIC16C716-20/SO can also be used for communications between the microcontroller and other devices, like a computer or mobile device.
