Motorola term some of their microcontrollers as automotive. What criteria do they use to distinguish between those which are automotive and those which are not? I tried to find a trend but could not! Does anyone know? Thanks Michael _________________________________________________________________ Express yourself instantly with MSN Messenger! Download today it's FREE! http://messenger.msn.com/ |

Michael, According to my knowledge the criteria is based on sales. The microcontollers that are developed for the Automotive industry, and are sold for the Automotive industry are classified as automotive. All the other HCS12 microcontrollers, and including some that are automotive and are popular for general market, are classified general market. Hope this helps, Doron Nohau Corporation HC12 In-Circuit Emulators www.nohau.com/emul12pc.html At 20:49 12/10/2004 +0000, you wrote: >Motorola term some of their microcontrollers as automotive.

This is no hard and fast distinction. However automotive is quite possibly Motorola's most successful market concentration-they probably have better market leadership and penetration in that area (in my opinion) than in any other, including wireless. Some of the classic microcontrollers widely used in many general-purpose markets were first designed for automotive, including the 68HC11 and 68HC12 families. They start out more or less as custom products, sold in the millions to GM, Ford, or Chrysler (or other automotive OEMs), then get productized for general use a year or two later. Power PC-based controllers are being used in engine controls, transmission controls, and antilock braking systems. 68HC12 class controllers are used for body control functions including driver door switches, memory seats, and the like. 68HC908 class controllers are used in lower-end body control functions requiring less processing power. In recent years, many automotive microcontrollers have built-in serial communications controllers intended for use in vehicle data networks. A few years ago this meant J1850 for the US, CAN in Europe. It's no accident that the first 68HC12 chips had these functions built in. Now J1850 is being displaced by CAN world-wide. (LIN is coming in for low-end modules, often on 68HC908 parts.) So one typical characteristic of "automotive" controllers is the presence of CAN on-chip. CAN is also used in industrial control systems (for example, DeviceNet), but I think automotive was Motorola's first and primary market for CAN. There are certain technical characteristics imposed by automotive that are not as widely present in other industries. One is temperature, -40 to +85 in all cases, to +105 if the module is in the passenger cabin but sunlight visible, to +125 if under the hood. Another is unusual attention to EMC issues, more so than in most other industries. Even if a processor series was originally launched in the automotive sector, they later broaden it out by adding new peripheral I/O needed in other industries, different packages, etc. Many processors end up being used both in automotive and in other sectors. Others are specifically for industrial controls, appliances, computer peripherals, etc. Best regards, Kerry Berland Silicon Engines 2101 Oxford Road 847-803-6860 Fax 847-803-6870 Des Plaines, IL 60018 USA -----Original Message----- From: Michael Farrugia [mailto:] Sent: Tuesday, October 12, 2004 2:49 PM To: Subject: [68HC12] Motorola Automotive controllers Motorola term some of their microcontrollers as automotive.

Probably the temperature spec., or perhaps common usage.

I tried to find a trend but could not! Does anyone know? Automotive type MCU Qualification : http://www.freescale.com/webapp/sps/site/aqtlink.jsp CAN and LIN bus features are specific standards, mainly for Automotive application. LIN protocol - for peripheral communication within automotive : http://www.mot-sps.com/files/microcontrollers/doc/reports_presentations/LINO VERVIEWPRESENT.ppt I think Kerry got some other requirements for Automotive.

Within the Freescale 8,16 and 32 bit microcontroller business groups there are
automotive focussed and non automotive (consumer/industrial) focussed teams, both of which
are responsible for new product development, hence you end up with auto parts and non auto
parts. However there is a large crossover of usage from Auto to non auto and some from non
auto to Auto. You will find that most of the non auto parts are qual'ed up to 105decC and
many up to 125 degC. When looking for info on new parts it is best to look in the automotive part of www.freescale.com as you will find info earlier in here then on the general section, but it won't make it any easier to get hold of pre qualified devices. Look here to get more info on the subject http://www.freegeeks.net/modules.php?name=Web_Links&l_op=viewlink&cid=1 Best regards freegeek www.freegeeks.net PS I am planning to publicise my web site on the 9th November (to coincide with Electronica), anyone interested in adding in links to their web site should plan to do it before then (add here http://www.freegeeks.net/modules.php?name=Web_Links), any registered user can add their own links. Also, anyone wanting to contribute articles, code snippets, application examples etc is welcome to do so. You will also see that I have a forum for users, anyone interested to become a moderator, just drop me a line. ----- Original Message ----- From: MW Ron To: Sent: Wednesday, October 13, 2004 4:56 AM Subject: Re: [68HC12] Motorola Automotive controllers Michael Farrugia wrote: > Motorola term some of their microcontrollers as automotive.
