Embedded systems are a form of digital control system that are used to control various electronic devices, typically in industrial and consumer electronic applications. The PIC16F87-I/ML is an 8-bit microcontroller developed by Microchip Technology, Inc. for use in embedded system applications. It is designed for use in many applications, including remote monitoring, factory automation, consumer electronics, industrial control, and home automation. This article will discuss the application field and working principle of the PIC16F87-I/ML.

The PIC16F87-I/ML is an 8-bit microcontroller with a memory capacity of 2k bytes of program memory, 128 bytes of RAM, and 16 I/O lines. It is developed using Microchip\'s high-performance Core-Independent Peripherals (CIPs) technology and runs at speeds up to 20 MHz, making it ideal for applications that need high-speed operation. It features an on-chip voltage regulator and an integrated analog-to-digital converter, allowing users to access both digital and analog signals from the device. The PIC16F87-I/ML also has energy saving power-saving modes, allowing it to operate in extremely low power conditions for extended periods of time. In addition, it is equipped with a wide range of safety and security features, including a watchdog timer, a reset circuit for when unexpected conditions occur, and an on-chip encryption engine.

The PIC16F87-I/ML microcontroller has numerous applications. It can be used in factory automation systems to control complex processes, such as sorting and counting objects. It can also be used in home automation systems, where it can be used to control lighting, heating, ventilation, and other home appliances. It is also used in remote monitoring systems, where it can be used to monitor sensor data and alert users to any changes in environmental conditions. In addition, it can be used in industrial control systems, where it can be used to monitor and control processes in factories and other industrial settings.

The working principle of the PIC16F87-I/ML is simple. The microcontroller has an internal central processing unit (CPU) that is responsible for executing instructions stored in its program memory. The instructions are written in assembly language and can be programmed using a computer. The instructions control the operations of the device, such as reading and writing data, controlling digital pins, and interfacing with external peripherals.

When the microcontroller is powered on, the CPU executes the code stored in its program memory. This code is responsible for setting up the microcontroller and running the program. The program can then retrieve data from external devices, such as sensors, and manipulate the data according to the instructions given. The data can be used to control the operations of the device, such as turning on LEDs or controlling motor speed.

Overall, the PIC16F87-I/ML microcontroller is an excellent choice for embedded systems applications. It is designed for use in a wide range of applications, from home automation to factory automation. It is equipped with numerous features, such as voltage regulation and on-chip encryption, making it ideal for use in security systems. In addition, its powerful CPU and on-chip peripherals make it capable of executing complex operations in a short amount of time.
