I've been trying to find a low-power flash storage solution. It needs to have built-in management (finding bad blocks, wear leveling, etc), so I've been looking at eMMC chips. But the specs on almost all chips in this family seem to be hidden behind some kind of barrier. With the good manufacturers, all you have to do is sign up for an account to view the datasheets. Some manufacturers (like Samsung) make it seemingly impossible to view any information on the chips, other than throughput.
How do designers normally find information about these sorts of chips? Is there any hope for someone looking to only produce a few thousand units or less? Should I call it quits and just use a microSD / microSD slot assembly?
EDIT While I am asking this for general advice about sourcing managed flash, I want to mention that my specific application currently only uses about 120mW. Additionally, only reading will be performed on the flash.
