 		 #167931 - Every extra pin needed can be very expensive
Responding to: ???'s previous message
As I noted, I would not be interested in a quantity of 1. More probably 1k or 10k units.
And I did mention that many microcontrollers don't need any external code or data memory, in which case every I/O signal used for a flash disk is one less pin for GPIO or any of the other special functions the processor may support.

If you have a 68-pin controller with 56 GPIO, 14 memory pins would represent 25%.
If you have a 44-pin controller with 32 GPIO, 14 memory pins would represent 44%.

Embedded SD Memory - anyone seen any?            01/01/70 00:00      
   what's the point?            01/01/70 00:00      
      A microcontroller != flash memory controller            01/01/70 00:00      
         of course not, it's just one task of many ;-)            01/01/70 00:00      
            You actually gain a lot            01/01/70 00:00      
               whatever            01/01/70 00:00      
                  even more to the roots            01/01/70 00:00      
                     Solderability not a problem            01/01/70 00:00      
            There are advantages            01/01/70 00:00      
      Memories can be purchased separately.            01/01/70 00:00      
         memories... of the shelf...            01/01/70 00:00      
            Pricey and consumes a lot of processor pins            01/01/70 00:00      
               an interesting overview            01/01/70 00:00      
               Is 8 pins a "lot of pins"?            01/01/70 00:00      
                  Not SD - the linked memory            01/01/70 00:00      
                     is 17 a very large number? ;-)            01/01/70 00:00      
                        Show me your solderable SD module            01/01/70 00:00      
                           there's nothing to prevent you from soldering a micro-SD            01/01/70 00:00      
                              That's stretching it a bit            01/01/70 00:00      
                        Every extra pin needed can be very expensive            01/01/70 00:00      
   There's cheap SD with PCI            01/01/70 00:00      
      Oddly enough ...            01/01/70 00:00      
         connector issue            01/01/70 00:00      
         The only "issue" is their connector            01/01/70 00:00      
            as opposed to MMC, which uses the same connector            01/01/70 00:00      
   Found it - "iNand"!            01/01/70 00:00      
      how does its cost compare            01/01/70 00:00      
         Dunno            01/01/70 00:00
