#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.
