Anybody have any experience with the FT232R USB-RS232 interface chip? or simular? I am looking at it as a built in solution for not using USB in my project.

Anybody have any experience with the FT232R USB-RS232 interface chip? or simular? I am looking at it as a built in solution for not using USB in my project.
check out the latest Microchip solutions, they have something similar if not better. MCP2200
FTDI has been doing this for years and most Operating Systems support it. It's even built-in to the Linux kernel.
I've used FTDI http://www.ftdichip.com/FTDrivers.htm and Silicon Labs chips http://www.silabs.com/Pages/default.aspx but it really depends on your aims. If you want to build it into a product for distribution, I would go with FTDI because of the wide support. If you're only interested in one-off for your own use, I would just use this...
Thanks guys. The FTDI seems like the most cost effective solution. No externals, Great driver support. I am not sure, will I still need a max chip or will this replace it?
MCP2200 only support 8N1, so be careful...
I'm using PL2303.
You need MAX232 or similar level converter.
I assume you want to interface with a PIC via serial and to a PC via USB. I cannot think of any situation where you need a MAX232. FTDI usually gives you numerous schematics covering several scenarios. They should answer any further questions for you. The datasheet says (p1)Quote:

The PL2303 http://www.prolific.com.tw/eng/Products.asp?ID=59 recommended by pedja089 is probably a viable choice as well. I've never used it at the chip level so did not include it but a Prolific chip (probably the PL2303) is used in the dongle type adapter I referenced. I have used it under Windows, Linux & OSX.
Thanks Dave, Somehow I saw -1.8 instead of +1.8. Hmmm must get eyes checked.
Ok, Thanks for all the help guys, still not sure which way I want to go but at least I know more now. :)
