The experience is huge, as well as the number of materials presented at elektroda, about this subject. Search at e-books download. If you need opinions, you'll have to be more specific. What is your project, what you are trying to realise?
Ajay said:We have done over 300 projects with the 8051 and have wealth of information and tools for this. Most of these projects were completed in the 90's.
However, we are NOT using the 8051 core for any NEW design anymore. The main reason for using 8051 in the past that it was at the right price for the right functionality. Now, you can get an ARM7 core with more on chip memory (Philips, Atmel, Oki to name a few) than the 8051. Even the soc available with the 8051 core still have to deal with the 64 kB code barrier (sure there are bank switching codes available but that is a bad fix for a problem which can be solved by using a better chip!!).
If you still want to use the 8051 core, please look at the uPSD chips from ST Microelectronics which come with 256 kB flash, 32 kB RAM and 2 serial ports. Nice design.
About the compilers, I believe the ke*il is the best (we have tried plenty of them) but when it comes to 8051, frankly coding in assembly works the best since you are always limited with memory (unless you are doing a small project, in which case, I would strongly recommend the Microchips!!).

Ajay said:NVP, if your application is small, consider the Microchip solutions. Very cheap (less than $1 for some chips!!) and have the right tools for small code. When the code size starts increasing, the debugging tools available on 8051 are simply too good. Look at Nohau emulators, simply great!

If you have access to Atmel AVR, you should also consider this MCU, they are sligthly cheaper than PIC and more powerful.nvp said:Ajay said:NVP, if your application is small, consider the Microchip solutions.

Hello Ajay,
I agree with you, But in our palce getting the micro chip IC is bit difficult. But I am getting 8051 with out any problem. Also 8051 is one of the good micro-controller. I will do this project in 8051. Later I go for micro-chip.
It is really great help from you....
Regards
NVP.
