hi frenz,

I have a doubt regarding the two most popular microcontrollers of this world, the AVR and PIC.

Is AVR better or PIC??? Though AVR is 4 times fast compared to PIC controllers in

most of the projects iv seen people use PIC especially PIC16F877A,Why? what so

special about PIC16F877A... I saw the datasheet of it and its similar to avr's atmega

8. I am very interested to work on PIC since one year but need to know the

advantages and its wide use in industries before getting into it. And i also found AVR

to be confusing becuz in AVR to clear a bit we need to WRITE 1 to that particular bit

and they have not given any explanation in datasheet. It works in opposite way to all

other microcontrollers. So pls guys i'll be waiting for a right explanation for this

question so that i can start to work with PIC ASAP!!! Thanks in advance.

The one reason I prefer PIC is its cheap with wide variety to choose from. Its easily available in Asian markets. Support for PIC microcontroller is excellent from microchip side. Which is another reason people prefer PIC over AVR when developing commercial projects.

I do not see much difference in using PIC/AVR. Both are single cycle executable. It depends on type of project you are working on. I feel budget and availability is main reason why PIC is preferred. Though if you want to go for technical differences, I suggest go though PIC and AVR architecture manual. Will give you detailed difference between both.

You can start with PIC18 series. Go to microchip website and select features you want in your controller. Microchip will give you filtered results. If you have specific requirements then let us know. If I had to select a controller I would go with PIC18F4550. It has got everything. From serial port to USB a great learning device.

Thanks a lot sir But one last question sir i'm in a dilemma whether to work with AVR or PIC. I have worked with AVR but not in depth...I want to build ma career in embedded systems so thought of working on a controller in depth so that i could do some nice projects and gain knwoledge. Now whats your suggestion sir whether AVR or PIC??

@ prajwalsnh
AVR is fast as compare to PIC
both has pros and cons
AVR is costly as compare to PIC
AVR has less derivatives as compare to PIC
AVR is in standard 28 ,40 and more than 40 pins but pic is available in each package and size
normally now PIC is used in professional circuits
on some places i see AVR also
here is a book on pic and avr
learn both

basically its your call I only had in depth of 8051 not even PIC/AVR when I came to industry. But Basics are same for all controller. Once you get a habit of reading datasheet and programming a controller. You wont find any difference working with any controller be it ARM, PIC, AVR or 8051. PIC is huge just like AVR. There is nothing that an AVR can do and PIC can't. So its only a matter of choice. Its your call now
