The following topics are addressed: 0) Rantings and ravings (to make the FAQ zero-based) 1) ABOUT THIS FAQ 1.1) Who put this FAQ together? 1.2) How can I contribute to this FAQ? 1.3) What newsgroups will this FAQ be posted to? 1.4) May I distribute this FAQ or post it somewhere else? 1.5) How about FAQs on other microcontrollers? 2) ABOUT THE 68hc11 2.1) The 68hc11 microcontroller 2.2) 68hc11 flavors 2.3) Sources and prices 2.4) Advantages realized in implementing control applications with this family of microcontrollers 3) SOURCES OF INFORMATION ON THE 68hc11 3.1) FTP sites 3.2) Mailing Lists 3.3) BBSs 4) 68hc11 PRODUCTS 4.1) Free languages and development systems 4.2) Free C compilers 4.3) Plans for 68hc11-based boards 4.4) Commercially available software 5) 68hc11 DOCUMENTATION 5.1) Periodicals 5.2) Books 0) Rantings and ravings Disclaimer: Just so it is understood, the "rantings and ravings" are MY rantings and ravings. 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. As far as whether this FAQ gets split or not, please send me your suggestions and opinions. Spare time is a rare commodity, and it would be ashame for me to go to all the effort of splitting this FAQ, only to find out that everyone starts to complain about the multi-part format. So what'll it be - one part or multi-part? A new feature in 8051 FAQ is a list of individuals who have expressed interest in helping others with hardware and software problems for 8051 systems. Any one out there who's willing to offer assistance to the hc11 crowd? If you feel you are qualified, and you're willing to do a good turn, let me know what your areas of specialization are and I'll put together a list for this FAQ. Thanks! Take care, Uncle Russ 1) ABOUT THIS FAQ 1.1) Who put this FAQ together? I started by putting together a FAQ on the 8051 microcontroller in response to my own frustration in finding information. The FAQ has now been out for some time and has been very well received. One of the questions that I'm frequently asked is if I know of a FAQ on the 68hc11. Not only that, but how many times have you seen the following questions posted on the newsgroups: "anyone know of a C compiler for the 68hc11?", "anyone know of an assembler for the 68hc11?", and so on. Therefore, I decided to jump in and try my hand again. I figured that this would be a good learning experience. From what I've seen so far, the 68hc11 is a good chip, and well worth learning and developing with. I really don't have any experience with the 68hc11 (yet), so I'm going to need everyone's help on this. Just as with the 8051 FAQ, with everyone's help this FAQ should turn out to be a pretty useful document. 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 Smail address is: Russ Hersch HaVradim 11 Ginot Shomron ISRAEL The list of individuals who have sent suggestions and encouragement has overflowed. I hope it suffices to say "Thank you to all who have contributed to this FAQ - we all appreciate it." Special thanks to: David Dunfield (Dunfield Development Systems) Kevin Johnson (VSI, New Zealand) for the excellent product summaries Bob Boys Very, special thanks to Ping Huang and Thomas Koenig of the news.answers moderators team for all of their help. I certainly hope that those of you who know of interesting items for the 68hc11 will share with everyone by contributing to this list. If you are a manufacturer and have an anonymous ftp site available that supports the 68hc11, please let me know by Email so that I can add it to this FAQ. Also please feel free to keep me updated on your products. 1.3) What newsgroups will this FAQ be posted to? This FAQ will be posted to the following newsgroups: comp.realtime comp.robotics sci.electronics comp.answers sci.answers news.answers The first three newsgroups often contain discussions, announcements, or information on the 68hc11. Check them out from time to time. By posting to the *.answers newsgroups, the FAQ will automatically be archived. The archive name of this FAQ (also included in the header) is: microcontroller-faq/68hc11. 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 68hc11 users. comp.sys.m6809 comp.sys.m68k 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, and the only thing that I intend to gain from it is more information on the 68hc11, and getting to know my fellow 68hc11 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.

Depending on the variety, the 68hc11 has built-in EEPROM/OTPROM, RAM, digital I/O, timers, A/D converter, PWM generator, and synchronous and ansynchronous communications channels (RS232 and SPI). Typical current draw is less than 10ma. Architecture CPU has two 8 bit accumulators (A & B) that can be concatenated to provide a 16 bit double accumulator (D). Two 16 bit index registers are present (X,Y) to provide indexing to anywhere in the memory map. Having the two index registers means the 68hc11 is very good for processing data. Although an eight bit processor, the 68hc11 has some 16 bit instructions (add, subtract, 16 * 16 divide, 8 * 8 mulitply, shift, and rotates). A 16 bit stack pointer is also present, and instructions are provided for stack manipulation. Typically multiplexed address and data bus. Onboard subsystems Timer - Main timer system comprises of a single 16 bit counter clocked at the E clock (2,3,or 4 Mhz - there is a programmable prescaler to slow it down if required). From this single counter run a number of input capture and output compare registers (3-4 IC, 5 - 4 OC). The IC and OC functions are very versatile, and pulses as short as 1 E clock can be generated. A-D Convertor - Typically 8 channel 8 bit A/D, although the G5 has a 10 bit A/D. Serial Communications Interface (SCI) - Asynchronous serial communications; Data format - 1 Start, 8 or 9 data, and one stop bit. Data rate - 150 - 312500 Baud (312500 is using 4 mhz E clock) Serial Peripheral Interface (SPI) - Synchronous serial communications, comprises CLK, DATA IN, DATA OUT and optionally chip selects. As well as using specific SPI devices, it is very easy to expand IO using the SPI and standard logic devices (e.g. 74HC595 and 74HC165). 2.2) 68hc11 flavors The following are Motorola flavors: HC11 A Series 8K ROM (A8), ROMless (A0,A1), 256 RAM, 256 EEPROM (A1,A8), SPI, SCI, 3 IC 5 OC, 8 channel 8 bit A/D HC11 C0 Nice new device. ROMless, on board bank switching to support memory maps of up to 256K. Totally glueless interface - Chip selects on board, Read Enable and Write Enable signals now generated on chip. 256 RAM, 8 channel 8 bit A/D - Good pricing HC11 D Series Smallest and lowest cost member of the hc11 Family. ROMless (D0), 4K ROM (D3), 4K EPROM (711D3) - No A-D or EEPROM. Still has standard timers and serial ports HC11 E Series Same as A series execpt 512 bytes RAM and EEPROM. Pin compatible, only difference is one timer pin (PA4) can now be used for IC or OC instect of just OC. Also have EPROM devices and larger memory - hc711e9 (12K OTP), hc711e20 (20K OTP) HC11 F series ROMless, non multiplexed address/data bus with 4 chip selects built in. 1K RAM, 512 bytes EEPROM - otherwise same peripherals as E series HC11 G Series 16K ROM/EPROM, Non mulitplexed address/data bus, 512 RAM, 4 channel PWM, 10 Bit A/D convertor, 2 separate 16 bit timers HC11 K4 24K ROM/EPROM, 1Mb addressing using on chip memory mapping. Non multiplexed address and data bus. 4 programmable chip selects, 8 channel 8 bit A/D. 4 channel PWM, 768 bytes RAM Toshiba second-sources the 68hc11, and they list the following variants: A0/A1/A8 and E0/E1/E9. For a nice breakdown of the 68hc11 line, check out the file taxonomy.txt at cherupakha.media.mit.edu : /pub/miniboard/hobby-tips. The file contains a table detailing all of the possible combinations that the 68hc11 is supplied in. 2.3) Sources and prices Sources?? Prices?? Hell - you can't even find the suckers! For those of you who remember the old Chicken Man series on radio, "He's everywhere! He's everywhere!" - the 68hc11 is not Chicken Man. The 68hc11 - "It's nowhere, it's nowhere!" I remember one episode in which our hero was fighting against an evil plot to steal all of the refrigerator light bulbs in the world. Well, maybe the same thing happened with the 68hc11 - they just can't be found. Maybe it's just a clever scam. The 68hc11 really doesn't exist. Instead, Motorola cobbled together a microprocessor using an Intel 8051 running an emulation of the 68hc11 instruction set (Intel Inside?). Ruud Schramp found some in the Netherlands (sounds like an appropriate place to find them). The breakdown is as follows (1 US dollar =+- Dfl 1.70): Main Importer of Holland Dfl 15.-- (quantity >100) Main Importer of Holland Dfl 19.-- (if you buy 1 and if they want to sell 1) Distributor Dfl 25.-- (also no single sales) Shop (Display Electronica) Dfl 35.-- (quantity 1) Also, the 68hc11 can be found at the following places: Active Electronics 1-800-677-8899 Some prices from catalog #914: 68HC11A1FN 13.90 68HC11A0FN 13.40 68HC11A1P 18.75 68HC11A0P 16.40 68HC11E1FN 17.90 68HC11F1FN 29.85 68HC24 18.00 port replacement 68HCP11A1FN 14.90 68HCP11A0P 17.90 68HCP11A1P 20.90 68HC711D3S 26.90 (OTP) 68HC711E9FNX 37.50 (OTP) 68HC711E9FS 44.90 (OTP) 68HC811E2FN 28.40 They also sell evaluation boards JDR Microdevices 1850 South 10th Street San Jose, CA 95112-4108 USA Sales: (800) 538-5000 or (408) 494-1400 Fax Orders: (800) 538-5005 Tech Support: (800) 538-5002 BBS: 408-494-1430 They list the 68HC11A1P (48 pin DIP version) at $11.95 in their 1994 electronic component catalog (#37).

Location: bode.ee.ualberta.ca : /pub/motorola/68hc11/gcc cherupakha.media.mit.edu : /pub/miniboard/gcc A freeware version of the Hi-Tech C compiler is available for evaluation and tinkering. This compiler produces crippled assembler output only and does not include libraries. A method was developed and uploaded to make the compiler output usable. Program: Hi-Tech C Description: demonstration version of the Hi-Tech C compiler Author: Hi-Tech Software fixup stuff has no identification Location: design.fen.qut.edu.au : /hitech - the compiler itself cherupakha.media.mit.edu : /pub/miniboard/incoming/CheapSkateC - fixup stuff I've been playing with the Dunfield Development System lately (on the 8051), and it's 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. 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. Another decent C compiler comes from ImageCraft. This package, which runs under DOS and OS/2, includes a near ANSI C compiler, assembler, linker, librarian, ANSI C functions and headers, and 90 page manual. The current release is version 1.02 of their compiler. The price is just $40. Initial feedback on this compiler seems promising. The pre-release versions are already in use by many of you, and will still be available as freeware. 4.3) Plans for 68hc11-based boards Board: F1 controller system Description: 68hc11f1-based microcontroller Designer: Peter Dunster Location: cherupakha.media.mit.edu : /pub/6811/F1-board Board: MIT 6.270 robotics board Description: 68hc11-based robotics microcontroller Designer: Fred Martin and Randy Sargent of MIT Location: cherupakha.media.mit.edu : /pub/6270 Board: Mini Board Description: small inexpensive 68hc11-based microcontroller system for robotic applications Designer: Offshoot of the MIT 6.270 project Location: cherupakha.media.mit.edu : /pub/miniboard Suppliers: Gregory Ratcliff (gratclif@magnus.acs.ohio-state.edu) 1763 Hess Boulevard, Columbus, Ohio 43212 (614) 487-0694 (late evenings EST) Mark Reeves (mdreeves@wart.nando.net) 1117 Braemar Court, Cary, NC 27511 FAX/voice (919)481-3170 MIT Epistemology and Learning Epistemology and Learning Publications MIT Media Laboratory 20 Ames Street E15-301 Cambridge MA 02139 4.4) Commercially available products Many firms (large and small) offer a variety of 68hc11 programming languages, support packages, and development systems.
