MOST
PICAXE have SPI
= Serial Peripheral Interface BUSS     I2C = Inter-Integrated Circuit BUSS

Chips with a "#" have an Enhanced version of SPI

Chips with a "" are future devices!

Chips with a "**" mean Data Memory is shared with Program Memory

Memory (lines) = Approximate number of lines of program code the chip can hold.
Data Memory   = Bytes of EEPROM memory on board. "128 (-Prog)" means 128 Bytes less the space needed for your program. 256+I2C means.
                              256 Bytes + any external EEPROM space you add via the I2C interface.)
Polled Interrupt = A process that automatically checks a pin in between each command to see if something has happened.

* = It is not mandatory to tie unused Inputs to ground or Vcc but there may be circumstances where doing so may help with things such as reduced
        power consumption, etc.  A 4.7k Resistor will do the job.

** = SERIN line must be pulled to ground – recommended is 10k Resistor but 100k  should work.  This is not necessary for the SEROUT pin.

NOTE:  Please let me know of  any mistakes.    Also, if you buy a PIC16F684 for example, from a manufacturer, it WILL NOT work as a PICAXE.
              PICAXE Chips have a Basic Interpreter internally so they understand commands you download into them; that's why any ol' PIC wont work!
