We have used the FTDI 232B and 245B chips with LPC2106. You can
probably use the bit banging mode to set things up for
bootstrapping. We do the initial software load through the
serial port, and then do updates using our software and the IAP
routines.
The boards with LPC2106 and FTDI245BM are available from us. See

FTDI chip will run at 3MB but not the silab chip. It depends on what
speed you need. Also, I think the drivers are not free for silabs
but they are free at FTDI and they have 2 versions to pick from

Thanks on the advice!
I'm most probably going to go with FTDI. it seems that firmware/software
support is quite extensive. I'll probably throw in the footprint for the
other device (Philips) just to be able to play with USB more :-)
Cheers,

Milos,
We have had good luck using the FTDI FT245BM. DLP Design makes a nice test
module, the DLP-USB245BM, using this chip. With a little tweaking of the
power connection, it will make a nice self-powered USB device (i.e. with a
direct connection it doesn't boot the lpc 100% of the time).
Perhaps more importantly, FTDI provides a couple of interface options on the
host side- Virtual COM port for Windows, Mac, and Linux, as well as a DLL
for Windows.
HTH,
Curt

Hi everyone,
I wanted to fabricate a board with the LPC210x that will have USB
connectivity. I have found some simple chips that would definitely do the
job - for example PDIUSBD12 which is a USB interface device with parallel
bus. However, I don't think I would be able to bootstrap the LPC2100 via
USB
using this chip. I was wondering if any of you guys had some experience with
USB chips that have more logic and would be able to easily provide means to
bootstrap the chip. I know of USB controllers that feature the
microcontroller on them but I think that that would be an overkill.
Thank you all in advance,
Cheers,
Milos

Try the Cygnal CP2101 !
This is a small UART-To-USB Bridge Controller,
which is very easy to use.

Hi Milos,
take a look at the FT232BM from FTDI (www.ftdichip.com).

Milos,
We have had good luck using the FTDI FT245BM. DLP Design makes a nice test
module, the DLP-USB245BM, using this chip. With a little tweaking of the
power connection, it will make a nice self-powered USB device (i.e. with a
direct connection it doesn't boot the lpc 100% of the time).
Perhaps more importantly, FTDI provides a couple of interface options on the
host side- Virtual COM port for Windows, Mac, and Linux, as well as a DLL
for Windows.
HTH,
Curt
