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 |

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.

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

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, m. _____ From: Curt Powell [mailto:] Sent: Tuesday, August 31, 2004 11:40 AM To: Subject: RE: [lpc2000] LPC2100 and USB programming Milos, We have had good luck using the FTDI FT245BM.

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 --- In , "nourson54" <yannsuisini@h...> wrote: > check this : > http://www.silabs.com/products/microcontroller/interface.asp > > 3$,no other components around, and extended temperature range ... > > --- In , "Milos Prokic" <mproki@m...> wrote: > > Thanks on the advice! > > > > I'm most probably going to go with FTDI. it seems that firmware/software > > support is quite extensive.

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.
