It's only unique as to it's pin configuration - there are loads of arm cores out there with memory controllers & lcd controllers built into them, and I would of thought you'd know that the smc controller is just software considering that you have built an sdk around it
It's true that the PSP is only cpu speed locked due to battery capacity.
A SMC card is a Memory Card with Memory, but missing the Controller to organize the memory. This controller is build into the s3c240 chip ( look chapter 19 of pdf ). To control an SMC card you need, the SMC card, an controller (build in s3c240 chip ) and software to get access to the smc memory.
SMC cards are so damm dumb, a SD card is 1000x more nicer, comming with its own mem-controller.
The s3c240 chip offers, again,
LCD controller,
Memory Controller for SMC cards,
ARM9TDMI CPU core with memory controller (SD-RAM),
Sound Hardware, serial Bus, I²C-Bus, only connect a DAC and you have sound.
There is no other chip, supporting ALL the above features.

This chip, looks very close to it, but missing the MMC controller.

Wow, this chip looks very nice, someone wants to build a new machine with this chip ?
Count me in, i can design a nice layout with eagle ....
