The problem with that is an SD flash unit takes up a lot of space, costs more than I want to spend, and has way more storage than I need.</p> <p>The WiShield uses an Atmel Dataflash 45DB161D, a SPI 16MB flash chip. Pages are certified for 100k program/erase cycles.</p> <p><a href="http://octopart.com/at45db161d-tu-atmel-458823" rel="nofollow">http://octopart.com/at45db161d-tu-atmel-458823</a></p> <p>The SOIC version has a pretty small footprint, and is less the $4.</p> <p>I would have to port the AsyncLabs dataflash driver:</p> <p><a href="http://github.com/asynclabs/dataflash" rel="nofollow">http://github.com/asynclabs/dataflash</a></p> <p>Regarding the BKP domain registers - these are not ideal, as I would like the configuration data to survive power loss events. However, this may be good enough to use for a prototype. Thanks for mentioning them, gbulmer - I didn't know about them. </p>
