PIC16F871-I/L devices, otherwise known as Peripheral Interface Controllers devices, are high performance, low pin count, low-speed, 8-bit microcontrollers with a wide range of applications. They are specifically designed to offer a wide range of features, from high performance interrupt handling to chip programming and data storage. As with other types of microcontrollers, PIC16F871-I/L devices have both application specific and generic applications.Application Specific ApplicationsPIC16F871-I/L devices are ideal for controlling and monitoring the operation of peripheral devices such as motors, relays, or sensors. These devices are often used in the industrial automation and robotics industries, as well as in embedded systems. Additionally, PIC16F871-I/L devices can be used in motor control applications such as motion recording, motion control, and speed monitoring.Furthermore, these devices are used in data acquisition and control systems, providing the user with the ability to monitor and alter the data as it is transmitted by the device. Additionally, PIC16F871-I/L devices are ideal for use in various display systems, including LED and LCD displays.Generic ApplicationsPIC16F871-I/L devices can be used for a variety of generic applications, including data logging and programming a microcontroller. Data logging can be used to store and manage data, while programming a microcontroller can be used to write and execute code on a microcontroller. Additionally, these devices can be used as an interface between a computer and an appliance or between two appliances.Additionally, PIC16F871-I/L devices can be used for remote control, including remote control of a motor or a sensor or of a system. They can also be used for security control, providing control over the level of access to the system or data stored on the device.Working PrincipleThe PIC16F871-I/L device is based on an 8-bit Harvard architecture and operates with a clock frequency of up to 10 MHz. The user must configure and upload the device’s program memory contents prior to its operation. The device’s program memory contents are stored in two blocks of volatileEEPROM and two blocks of non-volatile Flash memory.The device also comes with several advanced programming features, such as direct memory access (DMA) and interrupt handling. Additionally, PIC16F871-I/L devices can be programmed in either binary or assembler mode.In terms of architecture, PIC16F871-I/L devices contain two memory maps: the program memory and the data memory. The program memory is organized in separate banks, each bank contains a number of instructions. The data memory is used for registers and variables.To execute programs, PIC16F871-I/L devices use a Harvard architecture where the program is stored in the program memory and the data is stored in the data memory. The device also features a 16-bit wide memory bus and an instruction set with a long word length (18 bits).ConclusionPIC16F871-I/L devices offer a wide range of application specific and generic applications, which make them ideal for a variety of applications. They are low-speed, 8-bit microcontrollers with a wide range of features, including high performance interrupt handling, chip programming, data storage, data logging, programming, remote control, and security control. Furthermore, they are based on an 8-bit Harvard architecture and operate with a clock frequency of up to 10 MHz.
