 		 #148375 - AVR can't execute from external RAM
Responding to: ???'s previous message
Reza Fallahati said:
Hello, As I remember you from your postings you are so professional that you should not have a religious feeling toward any MCU.

Nothing religious - just pointing out that a raw comparison between "128K Flash" on an AVR against "64K Flash" on an 8051 is not particularly meaningful.

Also, the OP specifically needs to execute code from externald memory - which, as Rullel noted, the AVR can't do:

                  I have no idea            01/01/70 00:00      
                     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      
   Started Again after the holidays            01/01/70 00:00
