David, I am afraid you misunderstood some probably wrongly presented information - the third column is the number of machine cycles (12 oscillator cycles each) of the "biblical" 12-clocker.

I am just looking into the STC12C5A datasheet, http://www.stc-51.com/datasheet...nglish.pdf , and I see the following:

AT89LP51xD2 ... coming?            01/01/70 00:00      
   Sounds brilliant!            01/01/70 00:00      
      Was it AVR who made low-quantity available? Or just spin-off            01/01/70 00:00      
         Probably true            01/01/70 00:00      
            Hobbyists and students are really important            01/01/70 00:00      
               Also...            01/01/70 00:00      
         That wasn't the only thing ...            01/01/70 00:00      
            Assembler            01/01/70 00:00      
               'LP simulator            01/01/70 00:00      
                  Good            01/01/70 00:00      
                  No ... I doubt he means that ...            01/01/70 00:00      
               That may have been the case, but ...            01/01/70 00:00      
               While that may be the case ...            01/01/70 00:00      
                  Never used C - planned to but had to settle for half memsize            01/01/70 00:00      
                     See ... 'C' can make the memory requirement greater            01/01/70 00:00      
                        But it ain't *necessarily* so            01/01/70 00:00      
                           Yes, that's a valid basis for the choice of 'C'            01/01/70 00:00      
                        Just don't kick in open doors            01/01/70 00:00      
                           Again, you may be totally correct about that ...            01/01/70 00:00      
                        sure, and so friggin what if ...            01/01/70 00:00      
                           well ... that's not exactly what I did ...            01/01/70 00:00      
      On chip debug            01/01/70 00:00      
         Why unlikely?            01/01/70 00:00      
            That's true.            01/01/70 00:00      
            Yes, that's what I meant!            01/01/70 00:00      
         Missed the point!            01/01/70 00:00      
            Ah, sorry.            01/01/70 00:00      
   Single Clocker LP Chips From Atmel            01/01/70 00:00      
   Samples            01/01/70 00:00      
      Samples            01/01/70 00:00      
         Samples            01/01/70 00:00      
            Samples Not...            01/01/70 00:00      
               they are good at that            01/01/70 00:00      
               Atmel says...            01/01/70 00:00      
               Samples Yes!!            01/01/70 00:00      
                  Nothing here yet            01/01/70 00:00      
                     you are not in the US            01/01/70 00:00      
                        No excuse!            01/01/70 00:00      
                        Envelope?            01/01/70 00:00      
                      ... "coming" ...            01/01/70 00:00      
                        Yet another missed opportunity.            01/01/70 00:00      
                           Sorry thought this thread closed ...            01/01/70 00:00      
                              Now maybe you guys will see why I don't use 'em            01/01/70 00:00      
                              hard to tell, but...            01/01/70 00:00      
                                 They're thrashing about, but ...            01/01/70 00:00      
                                    why the sigh ...            01/01/70 00:00      
                                       Probably not ... but you never know ...            01/01/70 00:00      
                                    datasheets            01/01/70 00:00      
                                       I'm glad they're there ...            01/01/70 00:00      
                                          Sad, but true.            01/01/70 00:00      
                                             Too much "designers"            01/01/70 00:00      
                                                it's that old bugaboo ... appearance over substance ...            01/01/70 00:00      
                                                I'd say            01/01/70 00:00      
                           "The part will only be available in about 3 weeks"            01/01/70 00:00      
                              I've heard/read that comment from them before ...            01/01/70 00:00      
                                 Common with delays for new chips            01/01/70 00:00      
                                    Quite so!            01/01/70 00:00      
                                    I have to remind the public-at-risk            01/01/70 00:00      
                                       Again            01/01/70 00:00      
                                          There's a purpose ...            01/01/70 00:00      
                                 I agree with Per !!            01/01/70 00:00      
                                    Not so, but it probably applies to every one of ATMEL's            01/01/70 00:00      
                           samples            01/01/70 00:00      
                              I tested...            01/01/70 00:00      
                                 The AT89LP4052 works very well            01/01/70 00:00      
                                    Looks good, so far, eh?            01/01/70 00:00      
                                       A typical op            01/01/70 00:00

                                             I will wait and see.            01/01/70 00:00      
                                                Transistors are cheap            01/01/70 00:00      
                                          I can't find that            01/01/70 00:00      
                                             Sorry. I thought it was unlikely.            01/01/70 00:00

                                 thanks            01/01/70 00:00      
                              Have you received those samples, Andy?            01/01/70 00:00
