The Sparkfun SOIC to DIP adapter worked fine for me. It was a little tight to fit but with a good soldering iron it can be done without much trouble.

Adapter worked nicely for me as well.
As a heads up there is some slight ambiguity in the datasheet for this part. To read from memory you send 22 address bits in 3 bytes (24 bits). It is not explicitly stated that remaining two bits go at the START, so you're sending:
2 dud bits
12 bit page address
10 bit byte address
=24 bits in 3 bytes
Maybe I'm the only one got confused over it =)

Seems to be a solid module. Haven't tested it yet. I should warn you though, the format is SOIC Wide, so the SOIC to DIP 8-Pin on this site doesn't really work (ESPECIALLY if you're new to SMD soldering, like I am.) There are other SOIC to DIP adapters available on the net that will work though. I ended up using one and the soldering became easy.

Here is a a simple but robust record-based file system to store log data on AT45D DataFlash: piconomic log_fs

Here is a Temp&Pressure Data Logger application (for Atmel ATmega328P): Temp&Pressure Data Logger

Datasheet link broken!

I have used the AT45 along with a Freescale MCF52233DEMO 32 bit processor for program memory, etc and they have done extremely well.

This product should include the word "memory" somewhere in the product description. Not for those of us reading it, but for those trying to find it.

Searching for "flash" leads to four pages of random: EL drivers, stepper motors, audio decoders, RFID readers, GPS modules, range finders, oscilloscopes, calipers, arduinos, ... and if you try to clean it up by searching for "memory", this doesn't show up at all. Product 525 has the same problem.

To be sure that I did receive the right chip. On top I see 128PH-1P1421-1, is that the chip above AT45DB161D?

Thank you very much.

BoB please! I am drooling for this...

fyi - i ended up calling an atmel distributor about these because we're using them in a design. looks like atmel is doing something funky to the supply of these things, as they're quoting me a 26 week(!) lead time on an actual order, and 2+ weeks on a sample order.
i found a site (diydrones) that has ~400 of these in stock at the time of this post, and got what i need, but i think i'll be getting away from this specific module.
sparkfun: there's a number of other companies (winbond, etc) that have similar capacity eeproms in 5.3mm 8-soic packaging. that might be a better option for the site.

Dear SparkFun,
do you think we can get those before March? I would like to place my order using credit from the FreeDay ;) And I'm just waiting for this little thingy :)

Humm, actually I see one problem for me, it uses too many pins compared to the EEPROM 2 Wire solution. ;-) Also, this is a SD Card solution are similar, while the SD Card holds 2 Giga Bytes (this is only 2 Mega Bytes) but the SD Card requires a 512 bytes buffer for reading and writing. (unless I'm wrong, of course)

Another n00b question. What's the main difference of this and the 24LC256 EEPROM? (besides size, of course) And can I use this with regular Arduino I/O pins? (not the Serial pins) Thanks again.

Will you guys order more of those? Or something similar? Thanks.

This is a great little chip. With a page size of 512 bytes, it works well with the FAT file system. I've got this chip working in the place of a SD card with a LPC2148 and it works great.

with a 14ms page record time. does this mean it takes 14ms to right something into the memory chip? as this would seriously limit the sampling frequency you could log at.

How about a breakout board, guys?
