Some semiconductor guru can explain what that means, I'm a software guy <IMG alt=":smileyhappy:" class="emoticon emoticon-smileyhappy" id="smileyhappy" src="http://freescale.i.lithium.com/i/smilies/16x16_smiley-happy.gif" title="Smiley Happy" /><BR /><BR />The CPU itself was originally called "Star 12", as opposed to the existing MC68HC12. Luckily, someone decided to abandon that silly name and shorten it to S12. Probably because it sounded too similar to the Starcore DSP?</BODY></HTML> Tue, 14 Apr 2009 13:33:58 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Trivia-Question-What-does-the-HCS-as-in-HCS12-stand-for/m-p/171084#M5752 Lundin 2009-04-14T13:33:58Z Re: Trivia Question - What does the HCS (as in HCS12) stand for? https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Trivia-Question-What-does-the-HCS-as-in-HCS12-stand-for/m-p/171085#M5753 <HTML><HEAD></HEAD><BODY><P><SPAN>High-speed CMOS</SPAN> is what <SPAN>"HC"</SPAN> stands for (e.g. 74<SPAN>HC</SPAN>573).&nbsp; The letter <SPAN>"S"</SPAN> was added when the designs migrated to a smaller-scale fabrication process, which resulted in a <SPAN>s</SPAN>maller, <SPAN>s</SPAN>peedier product.</P><P></P><P>Best regards</P><P>Carl Barnes</P><P><A href="http://www.technologicalarts.com/">www.technologicalarts.com</A></P><P><SPAN>Evaluate * Educate * Embed</SPAN></P></BODY></HTML> Tue, 14 Apr 2009 22:11:50 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Trivia-Question-What-does-the-HCS-as-in-HCS12-stand-for/m-p/171085#M5753 mculater 2009-04-14T22:11:50Z
