Is this a school assignment?

The "Family" they are talking about is the family of hundreds of 8052 derivatives that I mentioned in my last post. All these chips are a "family" because they all contain the 8052 "core." This means they all share the characteristics contained in the 8051 tutorial.

In addition, each "member of the family" (derivative chip) has its own features and specifications. Some chips have A/D converters, others have features that allow them to be connected to USB ports, others include on-board Flash memory, etc. Which member of the family you choose depends on the features you need. But regardless of which chip you use, it will still conform to the 8052 core which is explained in detailed in the tutorial mentioned above.

In your questions above, all four depend on which derivative chip you select. If this is just a school assignment and it doesn't matter which chip you select, just select any chip from the chips page, read the datasheet, and get your information from that. All the chips on this page are part of the "8052 family." i.e., they contain the 8052 core and are thus compatible with the 8052.
