I have a couple of SX52 protoboards from Parallax on their way because the SX48 protoboards are on back order. As I have never worked with these chips (only the SX28), I want to get a feel of what is different in them. From what I have been able to find out the major differences between them an an SX28 is a few more input commands and more I/O pins. What I don't understand is why the SX52 is being discontinued if it has more capability (meaning 4 additional I/O pins on RA) than an SX48. Was there a problem in manufacturing the die for them or something?
 

Also is there any header differences (or hardware setup with the SX-Key) I should be aware of when setting up an SX52 as compared to my normal header for an SX28?

 

If the SX28 header is:

 

DEVICE      SX28, OSC4MHZ, TURBO, STACKX, OPTIONX, BOR42
FREQ          4_000_000

 

Would the SX52 be:

 

DEVICE      SX52, OSC4MHZ, TURBO, STACKX, OPTIONX, BOR42
FREQ          4_000_000
