In SX Microcontrollers, SX/B Compiler and SX-Key Tool, PJMonty wrote:

Waveman,

1 - I'm not real versed in Basic Stamp-ville, but I'm pretty sure the answer is, "No" with regards to the schematic.  The Basic Stamp has other components (such as EEPROM to run programs) that the SX48 doesn't need.

2 - The BS2P is a complete circuit on a PCB that has an SX chip along with EEPROM and some other stuff.  The SX48BD is simply a naked SX chip, period.  You need to design an SX48 into a circuit with the (minimal) required support stuff (clock source, pull-up resistor on the MCLR line, etc), whereas with the BS2P you pretty much add electricity and start running.  The SX48 can be programmed using SX/B, but it requires an SX-Key to actually download and debug the chip.  The BS2P just needs a serial cable.

3 - More pins and double the internal space for storing programs.

4 - SX/B.

5 - Others will have more input on this as I program in assembly.  However, I know that a lot of effort was put into making the languages compatible wherever possible.

Thanks,
PeterM
