I have this Atmel memory of 16Mbit: http://docs-europe.electrocomponents.com/webdocs/0dc4/0900766b80dc4809.pdf
Somebody can help me to use it??
Thank's all!!!
Looks like it uses SPI.
Wire it this way:
FLASH 1 SI <- Arduino MOSI (D11)
FLASH 2 SCK <- Arduino SCK (D13)
FLASH 3 RESET <- +3.3v
FLASH 4 CS <- Arduino data pin, typically D10
FLASH 5 WP <- Arduino 3.3v
FLASH 6 VCC <- Arduino 3.3v
FLASH 7 GND <-> Arduino GND
FLASH 8 SO -> Arduino MISO (D12)
Set the CS pin LOW to activate it.
Use SPI.transaction() to send commands and receive results.
Set the CS pin HIGH to end the command.

Atmel actually wrote a library to talk to this chip. It works very nicely. Check out the DataFlash library.
