#172204 - It's Not Really So Complicated--And....
Responding to: ???'s previous message

It's not really that complicated, relatively speaking. As the post above suggested, you need to remember that it is because it is based on the old 8051 architecture.

Yes, you CAN get large internal memory, but based on what constraints? What is the correct part for your application? What are your clearly defined requirements for hardware and software?

32K (or less!) RAM is more than enough in some larger applications. Even 8K or whatever is sufficient when applied properly and when you've clearly defined your design requirements and are using proper software programming methodology.

We ran a whole board successully with one Silicon Lab. 8051 w/ 4K XRAM.

Need more Internal RAM            01/01/70 00:00      
   Yes, but they handle it the same as external RAM            01/01/70 00:00      
   Look here            01/01/70 00:00      
      Ok            01/01/70 00:00

   It's Not Really So Complicated--And....            01/01/70 00:00      
      someone recently posted a link to a 805x with 64kB of RAM            01/01/70 00:00      
      Proper methodology can't really bound the memory requirement            01/01/70 00:00      
      That's My Point            01/01/70 00:00      
   RAM expansion need not be complicated!            01/01/70 00:00

         No            01/01/70 00:00      
            unless you have external glue logic            01/01/70 00:00      
               Yes            01/01/70 00:00      
         "bible" time!            01/01/70 00:00      
      There are much larger SPI memories            01/01/70 00:00

                  When at electronics store            01/01/70 00:00      
                     Which one?            01/01/70 00:00      
                     How does that compare with ordering from outside?            01/01/70 00:00      
                        I've always had to do that!            01/01/70 00:00
