Big big big memory or tiny SDs!

[skimask]

Thanks Steve,
I have a 1 MByte chip from ST, but I would really like some acreage! How about the memory inside the thumb drives?

How about the Atmel DataFlash chips? They're gettin' big these days (big as in good capacity)

I played with this awhile back, converted it to PBP (which was a piece of cake). A bit on the slow side, could've had faster transfers had I used the SPI module on the PIC itself.

$2.37USD each at Digikey.

I've also used the Atmel Dataflash (AT45DB321C (32MB)). Worked well with Shiftin/Shiftout. Also worked with the Hardware SPI, just a little harder to setup.

The hardest part is finding a supplier with some in stock. I think I got some obsolete SOIC parts from Arrow, but it's been a while. Digi-key lists all of there compenents as Non-Stock, but you might give them a call.

I found a supplier for the micro SD sockets. I was thinking of breaking out the old "FAT" code and installing it permanently on the board. For my proto, I will more than likely use the ST part. The down side to the SD card is the power consumption...but you can't beat the $15.- price!
Thanks for the leads,
Ron

I just checked Digikey. Searched for 'Atmel Dataflash' and clicked 'Items in Stock'. I get 42 results for parts in stock, ranging from 1Mbit up to 64Mbit parts.

Yep. I must have narrowed my previous search too much. 16Mb SOIC for $2.37.
