The PIC16F877-20/L is a popular and powerful microcontroller from Microchip Technology. The device combines a high-speed 8-bit core with a robust set of peripherals, making it well-suited for a wide variety of embedded applications.

The device is based on an industrial 8-bit core and has 1024 words of on-chip program memory. It features parallel, synchronous, and cyclic I/O ports that can be configured for various communication formats, along with an 8-bit timer/counter registers, and 13-bit A/D converter.]

The PIC16F877-20/L also has a 10-bit PWM module, allowing a variety of waveforms to be generated and controlled. This allows the device to be used for a variety of closed-loop control applications. It also supports two levels of interrupt control, allowing the user to prioritize tasks according to their applications. This feature, combined with 8 programmable levels of security and an external reset, makes the PIC16F877-20/L a great choice for secure applications.

The 20/L version of the PIC16F877 is a low power, low pin count version of the popular PIC16F877 processor. It features an 8-bit core and an instruction set optimized for low power, low power consumption, and compatibility with technology already used in low power applications. The processor also has a low pin count of 20 pins, making it well-suited for applications where board space is at a premium.

The PIC16F877-20/L is designed to be used primarily in low-cost embedded applications, such as intelligent control systems, robotics, home appliances, and so on. It is well-suited for these types of applications due to its low power consumption and robust set of peripherals, which include UARTs, SPI, I2C and CAN bus controllers.

The low power consumption of the PIC16F877-20/L also makes it desirable for applications that require battery power or operate in a harsh environment. The processor can operate at temperatures from –40°C to +85°C, ensuring proper functionality in harsh conditions. The low cost of the device makes it a great choice for applications that require a low cost but powerful microcontroller.

The PIC16F877-20/L is designed to work in embedded applications on a low power, low pin count basis. To operate it, the user must first create a firmware program that is executed by the processor. This code is stored in ROM, and is read by the processor when it is running. The code can be written using any development platform that supports the PIC family of microcontrollers, such as C, BASIC, or even assembly language.

When the processor is started, it executes the code stored in its ROM, which includes the firmware program and various initialization functions. These initialization functions are unique to each device, and allow the user to configure the microcontroller for the specific application. Once the initialization is complete, the processor can begin executing the application code that was written in the firmware program.

The PIC16F877-20/L is a powerful and versatile microcontroller that is suitable for a wide range of embedded applications. The device combines a high-speed 8-bit core with a robust set of peripherals, as well as 10-bit PWM capabilities, and 8 programmable levels of security to make a great choice for low power, secure applications.
