Note also that the SD host does not *only* support memory cards. This likely covers the whole range of memory and SDIO cards, and it's likely that the kit contains a lot more than just code (ie, perhaps a whole hardware system to verify correct host behavior). Furthermore, it probably covers the whole encryption system the "Secure Digital" format is supposed to have. It would be similar to purchasing a whole USB host development kit for those who were planning on implementing he USB protocol stack not just in software, but in silicon. A fab would not blink at such a price, just as many professional engineers don't blink at $5k for their schematic package, or $2k for a compiler. I haven't looked a the kit, and perhaps I'm completely wrong, but when it's this much it's usually either not meant to be sold, or contains a lot more knowledge and hardware than one initially expects. Still, I'd rather spend that money elsewhere. -Adam On 9/1/05, William Chops Westfield wrote: > It looks like a full source code library and development kit that > covers several operating systems.
