<lekernel> who came up with that bright idea to have several tsop56 pinouts? even at a single manufacturer, e.g. micron, you can find both
<lekernel> of course, the one I need is not manufactured apparently
<mumptai> probably the same people who started to count the data-pins from 1
<lekernel> http://www.digikey.com/product-detail/en/JS28F640J3F75A/557-1602-ND/3927557 seems to have the same pinout, a bit faster, and smaller
<lekernel> but still plenty of space
<mumptai> bootloader + 2 x fw-image?
<lekernel> mixxeo has only 1 firmware image, and a smaller one than M1
<lekernel> and no filesystem
<lekernel> so we can definitely use a smaller flash chip
<mumptai> how did the conversion to kicad work out?
<lekernel> I didn't do it, no time/money for that
<lekernel> interestingly enough, it's ddr3 sdram for micron: http://www.micron.com/parts/nor-flash/parallel-nor-flash/js28f640j3f75a
<lekernel> "part status: production" looks good... maybe there won't be another NOR nightmare after all
<lekernel> hmm, the other one is also "J3/Strataflash series", to there's less risk of running into bugs imo
<lekernel> we should move to serial flash at some point
<mumptai> i think we had the pcm on some fpga board, and in the end it was programmed by xilinx impact, by telling it was some CFI flash
<lekernel> the micron part has a numonyx datasheet
<lekernel> almost the same as the one of the original flash chip, actually

<lekernel> arrow has it too
<lekernel> "in stock", they say. and then, 13 week lead time...
<lekernel> ah, no, that's for backorders
