MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The PIC16F877A is Microchip’s 8 bit microcontroller. It has 8K of program space, 33 IO line, 8 10-bit ADC pins. It has a maximum speed of 20 Mhz and can be programmed in circuit.

Detailed explanation-2: -The PIC16F877A-I/P is a 8-bit CMOS Flash-based Microcontroller.

Detailed explanation-3: -PIC16F877a is a 40-pin PIC Microcontroller, designed using RISC architecture, manufactured by Microchip and is used in Embedded Projects. It has five Ports on it, starting from Port A to Port E. It has three Timers in it, two of which are 8-bit Timers while 1 is of 16 Bit.

Detailed explanation-4: -The PIC16F877A is a 40-pin (DIP) microcontroller which Microchip describes as powerful based on having a 200 nanosecond instruction speed. It’s old and Microchip itself is not recommending it for new designs but its features and price make it still a popular microcontroller.

Detailed explanation-5: -The 8-bit PIC microcontroller uses a Reduced Instruction Set Computer (RISC) architecture that has a separate address and data bus. This means they can be separate in size as well. All 8-bit PIC microcontrollers have an 8-bit wide data bus but the program bus will vary in size depending on the family.
