It was in the German edition of EE Times. For those who can read German: http://eetimes.eu/germany/192501959;jsessionid=GHTVEE0QJRNJCQSNDLSCKHA > Anyone seen a price on this device ? > The last sentence "?ber den Preis machte der Anbieter keine Angaben." translates into "The vendor did not disclose pricing." :-( I guess it's targeted at the luxury sector. S-Class, 7-Series etc. Personally I don't like the idea of having to trust that the contents of those 3MB are bug free while cruising down an autobahn at 120mph. At least not for mission critical stuff in there. -- Regards, Joerg http://www.analogconsultants.com

At > least not for mission critical stuff in there. :) - tho I do see they have ECC on both the Flash and RAM, which seems to becoming something of a standard ( see also the XC166 series, tho I don't think that ECCs the RAM ? ) I presume a reasonable chunk of the 3MB is lookup tables , so the code should be much smaller (fewer lines = fewer bugs ? ) ? Up to 5 CAN busses ! - remember the early days of CAN when it was pushed to have one CAN bus over the whole car.... -jg
