Hi all
I have a project with PIC but I need EEPROM memory as large as 1MB for data storage ! What mem can I use ? SD card,CF card ?
I need your advice !
Thank you very munch

If you just need 1MBit of EEPROM space two 24xx512 EEPROMS would do the job.
see: DataSheet
They are easy to use with PBP.
What kind of data are you planing to store in EEPROM?
can it be "compressed" in some way?

Some will use smartcard stuff but, IMO it's easier/cheaper to use a stack of some i2c EEPROM like 24C512
OR :
1X AT24C1024 (I2C)
1X AT25P1024 (SPI)

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
Hi Don,
Have a look at the Atmel AT45D0xx DataFlash at: http://www.atmel.com/dyn/products/de...?family_id=616
Here's an article on using them with a BASIC Stamp you might find useful to help get started. http://www.emesystems.com/BS2flash.htm
Thanks BRUCE
AT45DB081 is just fine for me ! Low cost,high density !
Now, I try to learn read/write page mode !
I need to write, time to time,8 byte and this memory want entire page write at a time !
Thanks again
Don Mario
