SX48 Controller Board?

All--
I recently discovered the SX Controller Board which uses the SX28 chip. My question may be very simple and very obvious . . . to everyone but me!
I wonder why Parallax chose the 28 pin SX chip instead of the 48 pin SX chip with the extra I/O pins for the product?
It APPEARS that the SX chip is pretty much standalone except for power and·the external ocillators needed. (I am nowhere near to being well-versed in electronics.) Is there a schematic describing such a cobbled-together device?
Thanks!

It could be that people need a programming board to program the SX28 because it is a DIP chip
I don't ever put the SX controller board on a project because it's size dosn't go anywhere.
Recently I made a smaller SX board because of this.
Thats why I think it uses the SX28
