What is PIC architecture?
The PIC architecture consists of two memories: Program memory and Data memory. Program Memory: This is a 4K*14 memory space. It is used to store 13-bit instructions or the program code. The program memory data is accessed by the program counter register that holds the address of the program memory.
Which is better PIC or Arduino?
The Arduino is best because it is user friendly as compared to the PIC microcontroller because if we want to load program in the Arduino we just click on the upload in the Arduino IDE while in case of PIC we will perform complex steps in order to upload the code in the controller also Arduino is helpful in complex …

What are the advantages of PIC?
Advantages of PIC Microcontroller:
PIC microcontrollers are consistent and faulty of PIC percentage is very less. The performance of the PIC microcontroller is very fast because of using RISC architecture. When comparing to other microcontrollers, power consumption is very less and programming is also very easy.
Which software is used for PIC microcontroller?
Program the PIC Microcontroller
The PIC microcontroller programming is performed through ‘MP-Lab’ software. First instal the MP-Lab software, then select and install the compiler like CCS, GCC compiler, etc. Here ‘CCS C compiler’ is used for building the program.
How many bits is PIC16F877A?

PIC16F877A is the most commonly used entry-level 8-bit PIC Microcontroller. It is a 40-pin 8-bit Microcontroller with 14kB of program memory.
What are the features of PIC?
PIC devices generally feature:
- Flash memory (program memory, programmed using MPLAB devices)
- SRAM (data memory)
- EEPROM memory (programmable at run-time)
- Sleep mode (power savings)
- Watchdog timer.
- Various crystal or RC oscillator configurations, or an external clock.
Is PIC microcontroller used in industry?
At present PIC microcontrollers are extensively used for industrial purpose due to low power consumption, high performance ability and easy of availability of its supporting hardware and software tools like compilers, debuggers and simulators.
What is the size of flash memory in PIC16F877A?
What is the real size of the Flash Memory? 8192 words of program memory. You don’t normally count the extra words in configuration space (there’s a couple more up there as well as the configuration word.)
Which IDE is used for PIC?
MPLAB is the best IDE for PIC compiler.
How many levels of stack is there in PIC microcontroller?
These devices feature a 14-bit wide code memory, and an improved 8-level deep call stack.
How do I program PIC16f877A?
MPLABx Setup Steps
Step1: Open the MPLABx software and select the New project from File Menu as shown below. Step2: Select the Standalone option for the project. Step3: Choose the Controller(PIC16f877A) from the device drop down. Step4: Select the required programmer.
What is the stack size in PIC?
The PIC Stack
12 bit: A PIC microcontroller with a 12 bit core (the first generation of PIC microcontrollers) ( including most PIC10, some PIC12, a few PIC16 ) only has 2 registers in its hardware stack. Subroutines in a 12-bit PIC program may only be nested 2 deep, before the stack overflows, and data is lost.
What is program memory size of PIC?
The datasheet says that the size of the Program Memory is 8 K (8192 Bytes) .. so, I understand that that means I have access to registers from 0x0000 to 0x1FFF .. And that makes sense since it is what the Program Memory Map tells you .. This is “program memory” not “registers”.
