The PIC16F84A-20/P is a microcontroller manufactured by Microchip Technology Inc. It is a low-cost, high-performance programmable integrated circuit (IC) that is widely used in various electronic applications.
Here are some key features of the PIC16F84A-20/P:
1. Architecture: The PIC16F84A-20/P is based on a reduced instruction set computing (RISC) architecture, which allows for faster execution of instructions and reduces the number of clock cycles per instruction.
2. Memory: It has a program memory (flash memory) of 1K words (each word is 14 bits) and a data memory (RAM) of 68 bytes. The program memory is non-volatile, which means that the program code remains intact even after power is turned off.
3. Speed and Performance: The PIC16F84A-20/P operates at a maximum frequency of 20 MHz. It has an advanced Harvard architecture with a 33 single-word instruction set, resulting in high-speed execution and improved performance.
4. I/O Ports: It features 13 general-purpose input/output (I/O) pins that can be configured individually as inputs or outputs. These pins can be used to connect external devices, such as sensors, actuators, or other peripherals.
5. Timers: The microcontroller includes two 8-bit timers (Timer0 and Timer1) and one 16-bit timer (Timer2)
