 		 #160402 - So why didn't you say that in the first place?

I want to build such a Remote Control (Controlling by SMS)

So why didn't you say that in the first place - instead of just a virtually unanswerable, non-specific question like "What type of microcontroller has the biggest size of RAM in it?"

If you'd asked the real question in the first place, you would have had some useful suggestions by now!

Yes, SMS remote control is almost certain to need more than just the 128 bytes of "internal" RAM.

But it will certainly not require the microcontroller with the biggest RAM that you can possibly get!

I have an SMS-controlled project right here, right now that has been running successfully for many years on an 8051 derivative with 16K of MOVX RAM.

Another project included a TCP/IP stack and used an 8051 derivative with 32K of RAM.

So you don't even need a "super" 8051 with huge amounts of RAM (unless there's some other requirement that you still haven't mentioned...)

Again, you can search for available chips at: http://www.keil.com/dd/search_parm.asp

Need bigger RAM            01/01/70 00:00      
   find out here            01/01/70 00:00      
   MCS-51 is the best            01/01/70 00:00      
      Not for BIG RAM!            01/01/70 00:00      
         why not?            01/01/70 00:00      
            Disagree            01/01/70 00:00      
            Address range does matter            01/01/70 00:00      
               still, why not            01/01/70 00:00      
                  while I agree with Per, here is a nugget for Jan            01/01/70 00:00      
                     Large data:: Yes, large RAM: Watch out            01/01/70 00:00      
                     particular application of OP, not yours, matters            01/01/70 00:00      
                        And the best is...            01/01/70 00:00      
                        but added complexity equals likely more buggy            01/01/70 00:00      
                  "best" is the key.            01/01/70 00:00      
                  Addressing modes do matter            01/01/70 00:00      
               Why would anyone use THAT architecture?            01/01/70 00:00      
                  Helps to check context before reacting            01/01/70 00:00      
                     It is the architecture and not the brand            01/01/70 00:00      
                        Sorry if unclear            01/01/70 00:00      
            Quick PC history            01/01/70 00:00      
               engineering insight            01/01/70 00:00      
                  What was your point?            01/01/70 00:00      
            Possible to 16Mbyte            01/01/70 00:00      
      I use MCS51            01/01/70 00:00      
         So why didn't you say that in the first place?            01/01/70 00:00      
            The universal truth again            01/01/70 00:00      
               64kB RAM?            01/01/70 00:00      
                  Both            01/01/70 00:00      
                     don't be deceived by Keil's database            01/01/70 00:00      
                        Good to know            01/01/70 00:00      
         '51 vs '52            01/01/70 00:00      
         even with AT89C2051 can be done            01/01/70 00:00      
   ... and the BIGGEST is...            01/01/70 00:00      
      Is that RAM on-chip?            01/01/70 00:00      
      Maybe biggest, but BEST?            01/01/70 00:00
