Hi, I have a few questions regarding these cards.
Do they have 7 or 13 pins?
Scandisc datasheet v 1.3 page 14 has a 7 pin diagram, but the mmc standard jesd84-a441 has a 13 pin diagram. Looks confusing to me , since they both refer to mmc cards.
The datasheet is found at
Is there any updated version of that info? I tried to call a sales number for direct buy in appendix a but it has been disconnected.
I would like to use MMC for some data distribution and don’t want it to be copied. Can I use MMC or MMC secure is the only option I have? If data is copy protected, can it be read through SPI or I need to use normal card communication?
