    Hello all,

    Can the LH7A400-10 card engine support USB hosting? I want to connect a 128MB/256MB USB memory stick to the SDK board. The SDK board has both a USB-A connector and a USB-B connector.

    However I notice from the data sheet, that the LH7A400 sharp uP has only the USB slave side. While the LH7A404 uP has both.

    Any help on this would be cool.

    The LH7A400-10 card engine does not support USB host. This is because, as you said, the LH7A400 uP does not support USB host. If you absolutely needed to use the LH7A400 Card Engine, you could use an external USB chip, although I would highly suggest using the LH7A404 Card Engine instead.

    The SDK board contains both USB host and function connectors, although not all card engines support both. We use the same SDK baseboard for all of the kits.

    Thanks,
    -Mike A.
