Does any one know of a Chip that acts just like a SD Card? I am trying to get the functionality of an SD Card without having to get a socket and rather just having a permanent card on my board; Something that is Surface mount or through hole is fine.
I have been searching quite a bit, but haven’t found anything. Anyone know?
Personally I’d take the flash module components and @ Taylorza’s file system driver and use that, if I really wanted to do what you’re proposing. But what I have in my parts bin is a micro-SD surface mount holder
To get 32GB worth of Spansion flash, even in the biggest modules carried by DigiKey, it takes >1000 chips, and >$4500 plus shipping (but hey, you get a nice volume discount!), and then you have to wire them all up to the SPI bus, and use who-knows-what to manage the CS lines, a car battery or so to run the thing, no wear leveling, etc, etc, etc.
When it comes to flash, unless you don’t need much at all, MicroSD is extremely attractive!
Man, i had my head up my rectum when i said that. I am going to put some solder paste down and place it in the board oven and see if the SD card plastic can take the heat.
Just curious more than anything .
