RE: [lpc2000] LPC2100 and USB programming

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
