Learning the 8051

Can anyone recommend a book on the 8051 with a good explaination of
interfacing to one, especially with regards to memory mapped I/O and how
the timing works? I don't have much of a background in using
microcontrollers (this is a hobby right now).

www.8052.com has  lots of information.... you will have to search around 
this web site.

www.8052.com  has some very good forums where you can post questions.... 
(warning not all people who reply to the forums are experts.... )

Probably not as most of the 600 odd variants of the 8051 family (none of 
which are made by Intel anymore ) have extensions to the basic mode and 
in any event tend top be based on the 8052

For books see

for other 8051 stuff see

Actually, the 8052 is identical to the 8051 aside from memory sizes.  

Most of the derivative part data sheets are complete only in
presenting the delta from the original. Books on microcontrollers tend
to be quite unreliable-- aimed at beginners, yet filled with errors
and omissions. 

Without a sound understanding of the original, one will be forever
operating at a disadvantage. The MSC-51 Family Reference Manual is
still pretty much an indispensable reference-- particularly the
architectural overview and programmer's guide sections. Similarly,
some of the classic application notes. 

What has usually changed is the peripherals and the electrical
characteristics. And, often, the timing of the instructions.  Not
much, if any, change to the instructions since the move to CMOS.

Trying to master the 8051 without the original Intel documents is like
trying to master C programming without bothering to acquire a copy of
K&R. And all the worse if you try to do it from thick error-filled
books that were churned out in a few weeks each.

Hi John,

Welcome to the fabulous hobby of 805x microcontroller engineering. You'll 
find it a sometimes tricky, but tremendously rewarding and great value for 
money hobby.

Once you've oriented yourself a little, then please visit my 805x website. 
You'll find an ever expanding gallery of projects and lots of free 
microcontroller software to download.

It's good to have you aboard, John.

Regards,
Tressie

The common 8051 background docs are also here :

8051 Microcontroller Instruction Set  (50 pages, revision C, updated
07/06)
http://www.atmel.com/dyn/resources/prod_documents/doc0509.pdf

8051 Microcontrollers Hardware Manual  (113 pages, revision E, updated
01/07)
http://www.atmel.com/dyn/resources/prod_documents/doc4316.pdf

You will also need the specific device DataSheet, of course !

If you need a second-opinion datasheet, the ones here are well
presented,
and not simple paste copies of the same master...

http://www.coreriver.co.kr/product-lines/top_corerivermcu.html

Which 8051 are you using ? If you are new, choosing one with On-Chip
DEBUG
is a very good idea -

www.SiLabs.com have some good ToolStick models

Their datasheets are also quite complete.
