Oliver Thamm's HC08 Web

Welcome to HC08Web.de!

The HC08 is a low-cost, Flash-based, 8-bit microcontroller family offered by Freescale, formerly known as Motorola Semiconductor. The various family members have all kinds of integrated peripherals, are in-system programmable and have an extended HC05-based von-Neumann architecture. Latest addition are the advanced HCS08 chips, providing even more features, including low-voltage operation.

There are several reasons why the HC08 and HCS08 become more and more popular. During my work as a microcontroller consultant, I heard of many interesting information, links and resources for the HC08 microcontrollers - and finally started to collect and publish it on this web site.

So, if you find some valuable information about HC08 and HCS08 microcontrollers, have made an HC08 project yourself or if you're a vendor of commercial HC08 stuff - let me & the community know!

Happy HC08ing! Oliver Thamm

Links to HC08 Resources on Freescale Servers
Freescale (formerly Motorola) manufactures a huge amount of silicon - you'll find out if you ever search Freescale's web resources for a specific information! Actually, I have given up to update my deep links, because they seem to change continously. So, find out yourself, starting at: ...engineer's chat room:
Mailing Lists and Newsgroups
While other manufacturers host large community-driven interactive systems on their websites, Motorola has decided to close their own HC08 mailing list in May 2002. It has been a nice forum for years, thanks to all users who have participated so actively. Now, there is only a Yahoo group dedicated to HC05 and HC08 issues. Some poeple like it - some do not.

The following Internet Mailing Lists discuss HC08 topics. BTW: it's a good idea to read the messages on the list for a while to learn how the Mailing List subscribers communicate, before posting your own messages or questions.

Mailing List operated by: Motorola ImageCraft Software Yahoo Groups
Administration email address of the list server: n/a icc-mot-request@imagecraft.com -
Administration Web interface of the list server: n/a http://www.dragonsgate.net
Subscribe to the mailing list: n/a icc-mot-request@imagecraft.com
Cancel subscription to the mailing list: n/a icc-mot-request@imagecraft.com
Email address for your postings and replys to the list: n/a icc-mot@imagecraft.com 68HC05_08@yahoogroups.com

To take part in a Mailing Liste you first must subscribe to the Maling List. To do so, just send an Email to the address of the List Server containing the message body "subscribe..." (see above). The Email's Topic line can be left empty - it has no meaning to the List Server.

Always use the right address: Commands (such as "subscribe" or "unsubscribe") go to the Address of the List Server. Messages always go to the Address of the List!

After your subscription to a specific Mailing List, the List Server usually sends a subscription confirmation. This message should be saved, because it also contains advice how to leave the Mailing List if required.

Currently there aren't any Newsgroups specifically dedicated to HC08 microcontrollers.
