    There was a mistake, I corrected it.

    It should interface easily to the Proto Board.

    Good.

    Why would X need an 8 bit flash like this though? Doesn't it have plenty of pins for other memory types?

    It depends on the chip, the new XS1-L1-48 single-core device only has 28 I/Os. I'm designing a PCB for it and I'll include a connector for my Quad SPI board.

    The board will plug into the XC-1/XC-1A boards which have 2x8 expansion connectors.

    I was curious about your X-men reference Leon.

    If i wasn't "rather proud of the achievement" how long would it have taken you to get there?

    Do you always belittle Propeller people on that forum?

    I don't think I belittled anyone!

    Let's just say i'm rather annoyed by your phrasing. I suppose I over-reacted.

    I thought "x-men" was rather humorous. Of course over there that makes us "p-men". Not so good:-)

    I think I used "propeller-heads".

    Excellent.

    X-men vs the Propeller Heads sounds like a film title.

    My PCBs just arrived. I'll assemble one of them and try it out on a Proto Board with Steve's software.

    Microchip has just announced a quad SPI part:

    They took over SST some time ago, to get hold of the technology.

    That's just a bigger version of the flash chip I'm using. I'm not exactly sure about how new it is, since it's mentioned in the old datasheet too. But, maybe it's just newly available...

    I sure hope Chip has included some way to interface the Prop 2 with this chip to get the full 320 MBit/s speed.
    If you need a fast, cheap, low pin-count way to boot the Prop 2, I think this is it...
