0) Rantings and ravings

Disclaimer: Just so it is understood, the "rantings and ravings" are
my rantings and raving. My readers are refined and sophisticated and
would never rant or rave. I, on the other hand, sit in front of the
TV in torn underwear and drink beer out of the bottle.

Yeah, I know, this FAQ is getting a bit long. I apologize to those
who aren't able to retrieve the whole document. I'm now working on
reformatting and splitting it up into multiple parts. I avoided this
for as long as possible, since it is much more convenient when the
entire article is only one piece, but - that's life :-).

If you follow Jan Axelson's articles in Microcomputer Journal
(formerly ComputerCraft magazine), you'll be glad to know that she
now has a new book out. The Microcontroller Idea Book is a hands-on
guide featuring the 8052-BASIC microcontroller. It explains how to
use sensors, relays, displays, clock/calendars, keypads, wireless
links, and more - with schematics, design theory, program listings,
construction details, and so on. Sounds good! Check out section 5.2
for more details.

Take care,

Uncle Russ


1) ABOUT THIS FAQ

1.1) Who put this FAQ together?

I was prompted to put this FAQ together in response to my own
frustration in searching for information, and to the constant
occurrence of requests for information on this subject in various
newsgroups. Hopefully others won't need to go through what I did.

Normally, I spend all day programming in assembler on an IBM PC.
With my hobbyist hat on I decided to try my hand at a little
microcontroller project design. When it came time to start, I had no
idea what to do. I had nothing to start with - no assembler, no
programming language, no simulator. I cobbled together a simulator
to help me learn about the workings of the chip. It's not being made
available to the public since I'm afraid the simulator isn't very
good. It was for my own use, so the user interface (there is none)
really sucks eggs.

I decided to search the net for information on the 8051. This list
was compiled the hard way, logging onto every anonymous ftp site I
could find and looking around. I also used Archie, other FAQs and
lists, and every reference to the 8051 that appeared in the various
news groups. It took a long time till stuff finally started popping
up. I saved all of my notes and the result was the first version of
this FAQ. Responses have been pouring in, and the result is a much
more complete and thorough FAQ.


1.2) How can I contribute to this list?

I please ask that if you have any suggestions or additions, or you
would like to correct any of the information contained herein, please
send me a note.
My Email address is: sibit@datasrv.co.il
My Snail-Mail address is:

The list of individuals who have sent suggestions and encouragement
has finally overflowed. I hope it suffices to say "Thank you to all
who have contributed to this FAQ - we all appreciate it."


Special thanks to:
Cecil A. Moore (Intel)
Carl Wall
Dave Dunfield (Dunfield Development Systems)
Kevin Self (Dallas Semiconductor)
Jason McDonald (Program Coordinator, MW Media)
Richard H. Barnett (Purdue University)
Daniel Drennan (Inquisitor Magazine)
Jan Axelson (Computer Craft magazine)


I hope that those of you who know of interesting items for the 8051
will share with everyone by contributing to this list. A good amount
of stuff if turning up thanks to everyone's help.

If you are a manufacturer and have an anonymous ftp site or BBS
available that supports the 8051, please let me know by EMail so that
I can add it to this FAQ. Also, please feel free to update me on new
products.


1.3) What newsgroups will this FAQ be posted to?

This FAQ will be posted to the following newsgroups:
comp.sys.intel
comp.realtime
comp.robotics
comp.lang.forth
sci.electronics
These newsgroups often contain discussions, announcements, or
information on the 8051. Check them out from time to time.

The schedule for posting will be once a month. I can't promise that
it will be on time, but I hope to post it on the 26th of each month.

You might also want to check out the following newsgroups, since they
occasionally have items of interest for you 8051 fans.
comp.lang.misc
alt.comp.hardware.homebuilt

A bit farther afield, but still of possible interest:
comp.ai.fuzzy
comp.dsp
sci.engr.control
sci.engr.semiconductors


1.4) May I post this FAQ to my local BBS?

I am putting no restrictions on the use of this FAQ except - It must
be distributed in its entirety with the copyright notice, and no
financial gain may be realized from it. After all, I have spent, and
continue to spend, a lot of time on this. The only thing that I
intend to gain from it is more information on the 8051, and getting
to know my fellow 8051 groupies better.

For this reason I have appended a copyright statement to the end of
this FAQ. I feel pretty silly doing this, but I just want to protect
myself. The copyright does not limit the use of this list for
noncommercial purposes. I hereby give my permission to one and all
to pass this list around and post it wherever you want - as long as
it is not for financial gain.

Thank you.


1.5) How about FAQs on other microcontrollers?

If anyone wishes to start a FAQ on another microcontroller, please
feel free to copy the format of this FAQ - I don't intend on
copyrighting the look and feel ;-). With a common format, we will
all benefit when trying to find information on a particular
microcontroller.

If anyone has any comments on the format itself, I'm open for
suggestions.

2) ABOUT THE 8051


2.1) The 8051 microcontroller

The 8051 is an 8 bit microcontroller originally developed by Intel in
1980. It is the world's most popular microcontroller core, made by
many independent manufacturers (truly multi-sourced). There were 126
million 8051s (and variants) shipped in 1993!!

A typical 8051 contains:
- CPU with boolean processor
- 5 or 6 interrupts: 2 are external
2 priority levels
- 2 or 3 16-bit timer/counters
- programmable full-duplex serial port
(baud rate provided by one of the timers)
- 32 I/O lines (four 8-bit ports)
- RAM
- ROM/EPROM in some models

The 8051 architecture is a tad bizarre, but then so are the
architectures of most microcontrollers due to their specialization
(check out the PIC for creativity). One vexing problem with the 8051
is its very non-orthogonal instruction set - especially the
restrictions on accessing the different address spaces. However,
after some time programming the chip, you can get used to it - maybe
even appreciate it.

One strong point of the 8051 is the way it handles interrupts.
Vectoring to fixed 8-byte areas is convenient and efficient. Most
interrupt routines are very short (or at least they should be), and
generally can fit into the 8-byte area. Of course if your interrupt
routine is longer, you can still jump to the appropriate routine from
within the 8 byte interrupt region.

The 8051 instruction set is optimized for the one-bit operations so
often desired in real-world, real-time control applications. The
boolean processor provides direct support for bit manipulation. This
leads to more efficient programs that need to deal with binary input
and output conditions inherent in digital-control problems. Bit
addressing can be used for test pin monitoring or program control
flags.


2.2) 8051 Flavors

The 8051 has the widest range of variants of any embedded controller
on the market. The smallest device is the Atmel 89c1051, a 20 Pin
FLASH variant with 2 timers, UART, 20mA. The fastest parts are from
Dallas, with performance close to 10 MIPS! The most powerful chip is
the Siemens 80C517A, with 32 Bit ALU, 2 UARTS, 2K RAM, PLCC84
package, 8 x 16 Bit PWMs, and other features.

Among the major manufacturers are:
AMD Enhanced 8051 parts
Atmel FLASH and semi-custom parts
Dallas Battery backed, program download, and fastest variants
Intel 8051 through 80c51gb / 80c51sl
Matra 80c154, low voltage static variants
OKI 80c154, mask parts
Philips 87c748 thru 89c588 - more variants than anyone else
Siemens 80c501 through 80c517a, and SIECO cores
SSI 80x52, 2 x HDLC variant for MODEM use


Advanced Micro Devices (AMD)
AMD has a number of enhanced variants including such features as:
dual data pointers, slave interface with arbitration unit, dual
port RAM, FIFO buffers, and others.


Atmel

The smallest current device is the ATMEL 89c1051, a 20 Pin FLASH
variant with 2 timers, UART, 20mA. ATMEL was the first with
standard pinout FLASH, and with more program cycles than other
custom pinout FLASH. These parts compete with OTP and MASK
product on price, but eliminate inventory problems and the hidden
costs of OTP development. This will put real pressure on
"vanilla" micros like PIC and ST6.


Dallas Soft Microcontrollers - DS5000(T), DS5001(T), DS2250(T)

The Dallas Soft Microcontrollers have standard 8051 cores with
on-chip non-volatile RAM instead of ROM. This gives the user the
ability to easily alter the system and is perfect for data
logging. These processors are available in both chip and module
solutions. Among the features included in this family of
products:
- on-chip non-volatile RAM
- loader in ROM for downloading programs (eliminates the hassle
of EPROM erase/program/install cycle)
- built in real time clock option
- watchdog timer
- software security (program and data encryption)

The DS500x is a standard 40 pin DIP package (well, mostly
standard, it is really a BOX which is about double the height of a
normal chip). The DS225x is a SIP version which is functionally
identical to the DS5000 but usually a bit less expensive.

The nice thing about having the RAM on-chip, is that the I/O ports
are unaffected. When the RAM is configured as CODE memory, the
DS5000 behaves exactly as a single-chip 8051. The NV-RAM is
static with a built-in lithium battery, and has no limitations on
the number of writes. You can download your code as many times as
you like without damaging the device. The DS5000 also includes a
loader in ROM, which permits you to bootstrap code into the RAM to
get underway. The loader and on-chip RAM have an encryption
feature with which you can protect your code from being read back
from the device if you wish.


Dallas High-Speed Micros - DS80c320, DS87c520, DS87c530

Real barn-burners - performance up to 10 MIPS! Dallas was the
first to speed up the core. Wasted clock and memory cycles have
been removed using a redesigned processor core. As a result,
every 8051 instruction is executed up to 3 times faster than the
original for the same crystal speed. Clock speeds from DC to
33MHz!

High performance doesn't just mean speed. High integration gives
the user 2 full-duplex hardware serial ports, 13 total interrupt
sources (6 external), watchdog timer, power management, power-fail
reset, and other features.


Intel MCS-51

Introduced in 1980, it has become the industry standard for
embedded control. Intel offers a wide variety of 8051 versions
with different configurations of on-board EPROM/ROM. Also low
power, high integration, and specialized parts are also offered.


Intel MCS-251

Intel has announced the MCS-251, which is 100% binary and pin
compatible with the 8051, but with a 5-15 times boost in
horsepower. This is achieved by a six fold gain in bus cycles,
and further hardware improvements to avoid wasted bus cycles.
Delivery early 1995.

Further performance gains are possible by recoding critical
sections to use the extended features of 16 and 32 bit data
transfers, arithmetic and logical instructions, register to
register operations, enhanced BIT manipulations and improved
control instructions. In addition to extra 16/32 bit
instructions, the 251 includes 40 register with Accumulator and
Index functions overlayed as 16x8, 16x16, 10x32.

Pin compatible parts allow instant performance upgrades, and the
binary compatibility truly preserves users investment in code and
tools. By staying firmly in the 80x51 camp, Intel allows users
transparent access to an enormous horsepower range. To further
improve throughput in numerically intensive areas, users can use
INTEGER, LONGINT and FLOAT libraries written for the MCS-251.


Philips
Philips has more 8051 variants than anyone else. Among the
derivatives that they have: 40MHz, 24 pin skinny DIP, low
voltage, quad flat pack (QFP) versions for saving board space,
OTP, I2C bus, and so on.

The 8xc575 line features high integration, with many built-in
features including built-in EMI/RFI suppression


Siemens sab80c517a

The 80c517a is one of the most powerful 8051 variants available.
It features high clock speed (40 MHz), and high integration with
32 Bit ALU, 2 UARTS, 2K RAM, PLCC84 package, 8x16 bit PWMs, and
more.


2.3) 8051 representatives and approximate prices (in USD $)

There are many, many varieties of 8051 out there. This is only a
small sampling of typical prices on Intel chips.

8031 (128 bytes RAM)...................................3.59
80C31 (CMOS version of previous).......................6.95
8051AH (256 bytes RAM).................................6.95
8051AHBASIC (w/Basic interpreter built in)............29.95
8751 (4K EPROM, 128 bytes RAM)........................26.95
87C51 (CMOS version of previous)......................39.95


2.4) Advantages realized in implementing control applications on this
family of microcontrollers

Popular - readily available and widely supported, a full range of
free and commercial support products is available

Fast and effective - the architecture correlates closely with the
problem being solved (control systems), specialized instructions mean
that fewer bytes of code need to be fetched and fewer conditional
jumps are processed

Low cost - high level of system integration within one component,
only a handful of components needed to create a working system

Wide range - ONE set of tools covers the greatest horsepower range
of any microcontroller family, other suppliers handle a number of
DIFFERENT and INCOMPATIBLE (and often single-sourced) cores to cover
the same power range as the 80x51, the 8051 provides a real cost
savings in tools, training, and software support

Compatibility - opcodes and binaries are the SAME for all 80x51
variants (unlike most other microcontroller families)

Multi-sourced - over 12 manufacturers, hundreds of varieties,
something for everyone with the security of ready availability

Constant improvements - improvements in silicon/design increase speed
and power annually, 16 Bit models coming from several manufacturers,
low cost skinny DIP models now available

Program: RISM and IECM51.EXE compatible host system
Description: RISM is a reduced instruction set monitor and
IECM51.EXE is its compatible host system for a PC
Comments: These two programs together constitute a bare-bones
method of developing 80C51 system code without an
emulator. RISM51X is installed in the target system
and connected to a host PC system through a serial port.
The host PC runs the debugger IECM51.EXE. Once the
system has been debugged, RISM can be removed and the
target can be run in stand-alone mode.

4.2) Free C compilers

Several commercial C compilers have evaluation versions available.
These are not too useful (even for hobbyist projects) since they
usually don't include libraries. However, they do afford the user
the chance to inspect the quality of the code generated. Among those
currently available:

An evaluation version of COMPASS is available from Production
Language Systems. This package includes a C compiler, assembler,
debugger, simulator, etc. and runs under Windows 3.1. This
package can be downloaded from their BBS:
(817)599-8363
Enter YY8051 as password for first-time login
(In case of difficulty, contact manvillec@aol.com)

The Keil C compiler evaluation package is available as a freeware
C compiler. It can be downloaded from:
ftp.kulnet.kuleuven.ac.be : /pub/MCS-51/keil-demo
Thanks to Christofe Huygens for setting this up.

A freeware version of the Hi-Tech C compiler used to be available
from various places. It seems to have disappeared however. It
might still be available at:
design.fen.qut.edu.au : /hitech

Mark Hopkins (of CAS assembler and 8051.ZIP fame) says he is working
on a C compiler. No word yet on when it might be available - but,
hope is on the horizon.

In most cases, it makes more sense to invest a bit, and get something
serious. I've been playing with the Dunfield Development System
lately, and its really quite nice. I've also heard many good things
about it from others. It includes a near ANSI-C compiler, run-time
library with source, assembler, ROM debugger, integrated development
environment, monitor with source, utilities, and other extras. A
high quality simulator is also available separately. Although not
freeware, the low price ($100), the features, all of the extra
goodies, and the good reviews make this a package worth looking at.
Also, if you're interested in working on more than one family of
microcontroller, Dunfield supports a wide range. This means only
needing to learn one system, instead of many.


4.3) Commercially available products

Many firms (large and small) offer a variety of 8051 microcontroller
variants, programming languages, support packages, and development
systems.

No endorsement is implied by inclusion in this list. I apologize to
anyone I left out; It's only because I didn't know about you. If
you want to be included in this list, just drop me a line - please.
Any corrections and additions appreciated.

5.2.2) Book reviews

Jan Axelson's review of her book:
The Microcontroller Idea Book


This is a hands-on guide that presents designs for use in data
loggers, controllers, and other small-computer projects. It
includes complete circuit schematics and parts lists, design
theory, example program listings, construction and debugging tips,
and vendor listings. Example circuits and programs are based on
the 8052-BASIC microcontroller. The book is loosely based on a
series of articles I wrote for ComputerCraft magazine (now The
Microcomputer Journal).

Chapter titles: microcontroller basics, inside the 8052-
BASIC, powering up, saving programs, programming, inputs and
outputs, switches and keypads, displays, using sensors to
detect and measure, clocks and calendars, control circuits,
wireless links, calling assembly-language routines, running
BASIC-52 from external memory, related products


Richard H. Barnett's summary of his book:
The 8051 Family of Microcontrollers

The book covers basic micros through complete projects using the
8051 family as examples. It is designed as a "lots of meat, very
little filler" type of text, but is very well-suited for use as a
handbook of project development using 8051 family parts. The book
stresses examples, both hardware and software. The hardware
examples are real working items including 3 complete projects in
the last chapter. Software examples are presented in both C and
assembly code. All of the program listings and other software
examples were imported electronically to the text eliminating
errors.

Richard Kendrick's review of the book:
8051 Interfacing and Applications
from Applied Logic Engineering

IN BRIEF

An excellent collection of interfacing circuits and well commented
source code in assembly. This is not a book for beginners as it
assumes the user is very familiar with the architecture of the
8051 and its registers. A disk of assembly source code listings
is included.

COMMENTS

This spiral bound book is thin (74 pages) but manages to cover a
lot of information. All of the sub-chapters have excellent code
listings with full comments, partial schematic diagrams, and an
occasional timing diagram. The chapter on using the serial port
is based on the MAX232 chip becoming so popular. A table of timer
reload values is provided to get standard baud rates but the book
only mentions the required clock frequency of 11.0592 mHz in the
first chapter. It also doesn't explain why a seemingly
non-standard crystal frequency was chosen. The dual UART channel
features the 2681 chip. The LCD chapter gives a small but
adequate explaination of the Hitachi controller chip usage on LCD
displays and a tiny fragment of data on display characteristics of
LCDs. The bank selection of memory is useful showing code and
schematic using five 62256 chips for 160K bytes of read/write
memory.



Richard Kendrick's review of the book:
Microprocessor/Controller Design
by Wayne P. Lichti of Business Data Computers

A lame little book better bypassed. As an introductory text,
Kenneth Ayala's book is the winner hands down. This book is a
poor rehash of the same information in Intel's or AMD's data book.
There is one code listing in the book and does little more than
tell the reader that the 8051 family of processors exist.

This book is 134 pages of wasted time. The schematics were
printed on a dot matrix printer and poorly reproduced. Many of
the sections are just a table or a paragraph with two or three
sentences. Use Ayala's book, you'll learn a lot more useful
information.


John Little's review of the book:
The 8051 Microcontroller: Architecture, Programming and Applications
by Kenneth J. Ayala

IN BRIEF

A good book for those who are already moderately familiar with
assembly language programming and wish to learn more about 8051
specifics. Has many example listings, all of which are very well
documented in terms of comments and explanations in the text. NOT
a book for absolute beginners OR hardware hackers looking for
circuits and applications.

1 - Microprocessors and Microcontrollers.
2 - The 8051 Architecture.
3 - Moving Data.
4 - Logical Operations.
5 - Arithmetic Operations.
6 - Jump and Call Opcodes.
7 - An 8051 Microcontroller Design.
8 - Applications.
9 - Serial Data Communication.

C - how to Use the Simulator.
D - The 8255 Programmable I/O Port.
E - Control Registers.


COMMENTS

In his preface to the book, Mr Ayala states that that it is
intended for "... a diverse audience. It is meant for use
primarily by those who work in the area of electronic design and
assembly language programming of small, dedicated computers".
Later, he goes on to refer the reader to the manufacturer's data
books for more information on hardware issues. This sets the tone
for the whole book, which is very much software orientated.

Anyone buying the book expecting to find reams of circuit diagrams
and details on how to build their own 8051 driven, automated car
assembly plant will be disappointed. In fact, most of the circuits
and applications shown are very much conceptual, with generic,
black-box outlines for most of the components. The single
exception to this is a fairly complete system (8031, EPROM & RAM,
jumper selectable memory sizes) in the chapter on microcontroller
design. Even then, there's no I/O shown (the txd/rxd are
unconnected).

Having said that, Mr Ayala does do a fairly thorough job of
working through the peculiarities of the 8051, with detailed
coverage of memory organisation, bit/byte level operations,
timers, interrupts and, at the end of the book, a complete chapter
on 8051 communication modes. Each area has relevant assembly
language listings, along with a detailed explanation of the
workings of the code.

Each section also has highlighted "comment" passages which point
out common pitfalls and reinforce critical points. Each chapter
ends with a summary of the important points covered and a series
of ten to twenty pertinent problems for the reader to solve. For
the most part, the answers to the problems can be found in the
text. In later chapters though, the reader is asked to elaborate
on various programming themes and to write assembly language
programs of their own to perform various tasks. The problems range
from the bland "Name twenty items which have a built in
microcontroller" (Chapter 1), to the more esoteric "Compose a
40-value lookup table that will generate a sawtooth wave using a
D/A converter" (Chapter 8).

It should be noted that the book is not aimed at the complete
novice. For instance, although assembly language listings are used
throughout, it is not until Appendix B that the reader finds out
what the assembler actually does and how the listings relate to
machine code. Even then, the complete neophyte will be left with a
rather empty feeling, as there are pages and pages of code, the
schematic for a (more or less) complete system and instructions on
how to use the assembler, but no information at all on how the
object code should be utilised (other than with the included
simulator - see below). If you don't already know how to blow an
EPROM, you're in trouble.

The diskette which accompanies the book contains the PseudoSam
assembler (which is used throughout) and an 8051 simulator. Both
being intended for use on a PC (it's a measure of how fast the
computer industry is evolving that a 5.25 inch diskette seems a
little archaic just three years after the publication date of the
book). The PseudoSam assembler ran fine on my system and I was
able to assemble several of the examples from the book and
successfully run them on a small, home-brew 8031 system. I was
totally unable to get the simulator to run. However, as it failed
on several different systems I'm prepared to believe that my
particular copy of the diskette was at fault.


SUMMARY

All in all, a recommended book for those who have previous
assembly language experience and wish to get to know details
relating to the 8051 microcontroller. While the internal
architecture of the chip is covered in detail, external hardware
and peripheral interfacing is not. Only the basic 8051/31 is
covered, with little mention of the other variants available.
There are extensive listings in the text, covering routines for
handling keyboards and displays, as well as timing loops and
communications. A large, clear typeface ensures that all of the
listings are completely legible. The layout and presentation of
the book is excellent, with a consistent, unambiguous style used
throughout.


Tim McDonough's review of the book:
C and the 8051: Programming for Multitasking
by Thomas W. Schultz

Schultz's book provides a brief overview of the 8051 architecture
but is primarily a discussion of multi-tasking software in an 8051
environment. He presents quite a few code examples. The examples
and the accompanying text show comparisons of how to accomplish
things in assembler, PLM, and C. The C examples presented are
based on Version 3 of the Franklin compiler but should be easily
understandable by anyone already familiar with C.

Later chapters in the book deal with more advanced topics.
Chapters are devoted to Real-Time Ideas, Timing and Scheduling,
Communications and Synchronization, Interrupts, Priority, and
Context, and Distributed Systems. The Real-Time Ideas chapter
briefly discusses six Real Time Operating System (RTOS) kernels
offered by several vendors. Later in the book some examples are
given to simple applications with and without using a RTOS.

All in all, a useful addition to my technical library. It is one
of the few 8051 books that goes beyond the basics and would be
particularly of interest to those contemplating their first
non-trivial 8051 design.
