 		 #160376 - Helps to check context before reacting
Responding to: ???'s previous message
If you read the thread, you will not be able to find anyone suggesting the use of 8086/8088/10186/... line of processors. In fact, ARM processors have already been suggested if the OP do need access to more RAM. Linear address space is always easier to use than banked/paged/segmented/indexed/serialized memory.

The 8088 was taken as an example of the complaints about the 20-bit addressing mode - even when the 20-bit addressing mode is many, many times more complete than the 16-bit data addressing supported by the 8051. I.e. if people didn't like accessing 20-bit memory address space with a 8088, then they definitely have a reason to dislike the use of a 8051 for accessing 16-bit RAM.

The goal must always be to select the correct tool for the job - and not continue with an existing too just because it is there. The world isn't built only with nails...

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
