We're looking for a flash device for a low-volume (batches size < 100) industrial product, in the 2/4/8 GByte range.
In applications like this we've previously used SD card, which is an obvious choice. For better mechanical robustness and device consistency, we'd really like to use a fixed IC in this product. It feels like eMMC is absolutely the obvious choice for this - avoid both the NAND management hassle and the downsides of SD-cards.
However, there is something about the supply of eMMC devices which makes me suspicious about whether they're a sensible choice. Supply from the usual catalogue companies (Mouser,DK and Farnell for us) is really patchy, with few parts listed, those that are listed not on manufacturers' websites and many with 1000-level MOQs. This is not just 'difficult' manufacturers (Samsung, etc), people like Micron who have DRAM parts widely available seem to be different for eMMC.
Obviously the Arrows & Avnets of the world list everything, but this doesn't mean I could actually have 50 parts tomorrow from them.
Is there something odd about eMMC (licensing, whatever) which I'm missing, which means that it's not being carried in the normal way? Are there people here with any experience of using eMMC in real, low-volume, production?
