8051, FREESCALE, PIC, AVR. which is better ?

I am presently working on developing applications using 8051 and freescale 8 bit microcontrollers.

I wanted to know. in what terms terms the 8-bit series of microncontrollers namely. 8051, PIC, FREESCALE, AVR. are better from each other and why?

Actually now I have to learn PIC for the rest of the projects that i have two accomplish.


rishi says:
8051 ---- for learning n getting started in embedded systems

PIC ---- reach peripheral set and tremendous resources at every level

AVR ---- user friendly mainly for hobbyist

freescale ---- used in industry.

see PIC,AVR, FREESCALE all are used equally.the difference lies just in the application where they are used.

8051 is not used in industry.its modern derivative are used where they r almost equivalent 2 pic n avr in features like u can check high performance 8051 from silicon labs.i use them n they r monsters really.

it isnt like that. many products till this date use 8051
example
(1)the coin box phones use atmel's 8052 at89c52 series. at least the 1se used
in india
(2)many mp3 players use 8051. where quality isnt an issue ie fr industrial purposes.if u want quality go fr vs2001(arm7 core)
(3)8051 is still used in card readers(sd,mmc and stuff----yes....there are ranges
from atmel)
(4)8051 is used fr protocol convectors ie usb to serial convectors,etc.
so it depends on the application frankly.

pic,avr,arm are equally important. cause at the end of the day.when you design a product the 2 most important things in your mind should be cost and quality.
so we have to choose the controllers accordingly.
