 		 #148255 - the whole thing seems like nonsense!
Responding to: ???'s previous message
Shehryar Shaukat,

If all you need to do is complement a value, you don't need an MCU or RAM at all. All you need is an inverter (74HC240).

Why do you wish to process the Intel-formatted HEX file locally? Can't you do that much better at the PC end?

As for the notion of operating a 33 MHz MCU at 40 MHz, the best you can hope for is that you end up with rubbish. The worst, of course, can be that you are sued to extinction, which is what you'd deserve if you deliver such a thing.

                     ARM Book?            01/01/70 00:00      
                  $1.50USD ARM            01/01/70 00:00      
                     Of course it is, however            01/01/70 00:00      
         Price issue            01/01/70 00:00      
   Why 3 MCUs?            01/01/70 00:00      
      The Reasons            01/01/70 00:00      
         AVRs won't have this problem            01/01/70 00:00      
            OK            01/01/70 00:00      
               Changing processor            01/01/70 00:00      
                  My two cents            01/01/70 00:00      
                  ARM is the right choice for the project of this Sc            01/01/70 00:00      
            I'd be VERY careful using ATMEL!            01/01/70 00:00      
               prototype testing is necessary            01/01/70 00:00      
                  Yes, you have to test them under extremes            01/01/70 00:00      
               Richards, can you suggest an alternative?            01/01/70 00:00      
                  NXP            01/01/70 00:00      
                  In short ...            01/01/70 00:00      
            Neither would a comparable 8051!            01/01/70 00:00      
               8051 is not french wrench            01/01/70 00:00      
                  AVR can't execute from external RAM            01/01/70 00:00      
                     Russell Bull is right            01/01/70 00:00      
                        just like any other uC            01/01/70 00:00
