• Programmable internal timers
• Programmable capture and compare module (CCM)
• Wide range of serial communication protocols
• Advanced interrupt controller for event control
• Expanded operating temperature range

Working Principle

The PIC16F876-20/SO follows a Von Neumann architecture and uses a single bus for both instructions and data. All instructions are 16-bits in length and are generally single cycle instructions. The PIC16F876-20/SO is responsible for executing instructions, transferring data, and responding to interrupts. The data is transferred to and from memory and other peripherals using a set of 7 different registers.

The PIC16F876-20/SO has two timer/counters, one used as a timer and the other as an oscillator. Both these timer/counters are used to accurately control the period and pulse width of the output signals generated by the PIC16F876-20/SO. In addition, the PIC16F876-20/SO incorporates an advanced algorithm to calculate the timing of events triggered by internal or external sources like interrupts, timers, or overflows.

The device also includes a programmable interrupt controller (PIC) to monitor and control external interrupts. The PIC16F876-20/SO architecture allows for both simple and complex triggering events to be monitored, allowing for applications such as motor control, process control and communication protocols.

Conclusion

With its range of features and its performance in terms of operations per second and low power consumption, the PIC16F876-2O/SO microcontroller is suitable for many applications. It is one of the most widely used microcontrollers on the market today in a variety of applications.
