'[EE] USB host or slave chip'

HOST mode USB !!!!
SPI !

Russell,

Maxim's new MAX3421E device is a full-speed (12Mb/s) SPI-to-USB bridge
device which can be configured to operate in either USB-host or
USB-slave
modes.

In slave mode it is compatible with their erlier slave-only MAX3420E.

It also includes 8 general-purpose inputs and 8 general-purpose
outputs
(presumably accessed via the SPI interface).

Package is 32-pin TQFN or 32-pin TQFP.

Priced at US$3.47 in 1k quantity.

For the price you would generally be better of with a micro having a
USB
interface on-board but if you needed to add USB to an existing product
this
might be a good solution (and possibly your only solution if you
wanted to
use host mode).

Regards,

Ken Mardle

That's fantastic timing Russell. That'll save my project a heap of
space and cost. (I need host mode USB to trigger a camera)

Cheers,
Zik

Hmmm, unable to get samples of it atm it seems online. thats depressing, I'm
wanting to try some USB host mode stuff aswell.

Have not tried this yet, but I thought someone here might find it interesting.

Host/Slave mode chip from FTDI that includes Disk I/O and a few other
things built in.

I did only a quick scan but I this seems to contain a general-purppose
microcontroller, but did not find documentation of the micrcontroller?

Right..
It looks like they are offering pre-compiled downloads that support
different USB tasks, as well as FAT file system. you then control
the chip via commands from a Parallel or Serial or SPI interface.
Not that anyone here would want to dig any deeper into their
embedded controller or anything. ;-)

Could be a good way to support a USB memory stick and FAT file support
easily though. I also see an audio playback module coming soon.

I just thought that some folks here might find it interesting. You might
get more from the FTDI homepage. http://www.ftdichip.com/

Very interesting.  We have a need for such a device.  The prospect of not
having to look at something made by Maxim is a plus.

Depending on what speed you need, I have been very happy with the SiLabs
parts.

Indeed, very exciting. FTDI does it again.

Thanks, Shawn, but we need a host controller, not a device.  Everyone does
devices (even PICs).  This is a detail which escapes a lot of people.

We've used Cypress SL811HS part for host side USB with PIC 18F.
