The PIC16F876A-I/SO is a popular 8-bit microcontroller chip from Microchip Technology. It is a member of the PIC16F series, which is widely used in various embedded systems due to its low-cost, high-performance, and ease of use.
Here are some key features of the PIC16F876A-I/SO:
1. Microcontroller Architecture: The PIC16F876A-I/SO is based on the Harvard architecture, which allows it to fetch and execute instructions simultaneously, resulting in faster execution times. It features an 8-bit RISC CPU with a reduced instruction set, making it efficient and optimized for low power consumption.
2. Flash Program Memory: The chip contains a 14KB programmable Flash memory, which can store the user's program code. This memory is non-volatile, meaning the code remains stored even if power is lost. The Flash memory is also reprogrammable, allowing users to update the program easily.
3. Data Memory: The PIC16F876A-I/SO has 368 bytes of RAM, which is used for temporary data storage during program execution. Additionally, there is an additional 256 bytes of EEPROM (Electrically-Erasable Programmable Read-Only Memory) for storing non-volatile data such as calibration values or configuration settings.
4. I/O Interfaces: The microcontroller offers a variety of I/O options
