Working Principle

The PIC16C65AT-10I/PT microcontroller operates on the basis of the Harvard architecture, where instructions and data are on separate buses. In this architecture, instructions are stored in the program memory and data are stored in the data memory. The internal memory of the microcontroller consists of 8K words of program memory and 256 bytes of RAM, both of which are programmable.

The microcontroller has a total of twenty bidirectional ports. Each port can be configured as an input or output and all ports have built-in pull-up resistors, making them suitable for interfacing with external devices. These ports can be used for such tasks as controlling motors, LCDs, LED matrices, and more. The microcontroller also features eight 16-bit timers, which can be used for timing operations and events such as implementing software delays, detecting frequency and pulse width of various electronic signals, or measuring the duration of an event.

The microcontroller has an on-chip analog comparator that can be used to compare two analog signals. The comparator can detect the difference between the two signals and issue an output signal when the specified difference is reached. The microcontroller also has a watchdog timer that can be used to reset the microcontroller if it is stuck in an infinite loop.

The PIC16C65AT-10I/PT microcontroller also has an interrupt manager, which can be used to inform the system that an external event has occurred. Some common applications of interrupt include power saving, responding to keyboard inputs, controlling analog-to-digital conversion, capturing signals from sensors and communicating with other devices.

Finally, the microcontroller also features two serial communication interfaces that can be used for communicating with external devices such as PLCs, PCs, and other microcontrollers. These interfaces can be configured for either asynchronous or synchronous communication and can also be used for bootloading applications.

In conclusion, the PIC16C65AT-10I/PT is an affordable, low-power microcontroller that can handle a wide range of embedded system applications. Its relative adaptability, programmability and low power consumption make it a viable solution for many different kinds of applications.
