<ul></ul><p>not using the ARM, awaiting results to decide what ARM to use. Flash may change. SDRAM should remain constant.</p> Colony Scout - Bug #1032: Part Changehttps://roboticsclub.org/redmine/issues/1032?journal_id=26352010-01-22T07:37:57ZKevin Woo
<ul></ul><p>All above parts won't work, the pitch is too small. New parts:</p>
<p>ARM AT91SAM <a class="external" href="http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=AT91SAM9260B-QU-ND">http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=AT91SAM9260B-QU-ND</a><br />SDRAM 256MB (TSOP)http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=557-1223-1-ND<br />Flash (dataflash, 32MB) <a class="external" href="http://mouser.com/ProductDetail/Atmel/AT45DB321D-SU/?qs=sGAEpiMZZMtI%252bQ06EiAoGxmVFCUiFwY7a3YMBA10F6M%3d">http://mouser.com/ProductDetail/Atmel/AT45DB321D-SU/?qs=sGAEpiMZZMtI%252bQ06EiAoGxmVFCUiFwY7a3YMBA10F6M%3d</a></p>
<p>Note on the SDRAM, the Eagle package seems to be wrong about the part numbers. I had to use the wrong "part" but its the same device.</p>
<p>We can actually go upto 64MB but the cost is about 10x which doesnt seem worth it. OS team said that they don't need more flash than that.</p> Colony Scout - Bug #1032: Part Changehttps://roboticsclub.org/redmine/issues/1032?journal_id=26692010-01-27T04:37:39ZKevin Woo
