Where may I get a copy of MMC specification?

Hi, there:

Where may I get a MMC card specification? It seems mmca.org asks for $
in order to download the specs...but I don't want to pay that...

Kevin - search for "MultiMediaCard Product Manual (Rev. 5.1) MMCProdMn_5.1"

I think I got it from www.sandisk.com

If you can't find it let me know, its a .pdf around 600k.

Afterthought - this doc may be from sandisks perspective and may not be the
full spec etc.

Thank you Rob. I got it and it is very useful.

Does the "MultiMediaCard Product Manual (Rev. 5.1) MMCProdMn_5.1" carry
sufficient information for me to do a project
with? Browsed through...seems true...

Best Regards,
Kelvin

I don't know Kevin - I'm probably behind you in this area!
It appears to have the info needed.

For me, the big question is where to get enough docs on the SD card
interface to interface to SD flash cards.  I don't care at all about
dealing with secured cards, but I do want to use the four-bit-wide
interface to get better performance as compared to MMC cards.
