Tiny and cheap little USB to UART bridge

VCP drivers for windows work great and its stand alone you just need to
connect TX/RX and ground.

Pretty neat!  Will it work under 98SE?

I suspect it's an FTDI chip on a neat little PCB- so the answer is 
probably yes.

Paul Burke

Yes I think it does work with Win 98SE. Its not an FTDI chip - you
couldnt fit one in that small size I dont think.

Its a Silicon Labs CP2101 according to the datasheet in an MLP form factor
(5mm square). Neat though - minimal external components required.

Yeah it works on its own - you dont have to have anything else there,
just the HR-USBUART connected to your micro via TX/RX and ground.

Yes, kind of like we did making a board that has pads and holes
in the same pattern as a DE9 so we could retrofit our RS-232:

Before using that chip, think about the company politics about not releasing
a linux open source driver (http://www.kroah.com/log/2004/11/18/).

yea, it has a internal 48Mhz oscillator, I wonder if thats just a
trimmed R/C oscillator, usually they aren't good enough for serial
timing,

All I can say is that I have used them with the 921600baud rate and it
works perfectly. I have had only bad experiences with the DLP ones
based on the FTDI chip and their support was terrible. I am sure Si
Labs will address the Linus issue in time...
