Eventually look at FT8U245AM chip from FTDI (www.ftdi.co.uk). I understood that Cypress it's a little bit too expensive.

USB low speed

You can use CY63001A is a good choice and is not expensive. This device is very used in software keys. I have attached a pdf for your information. Regards.

Hi,

After a small investigation it seems Cypress solution for low speed need is cheaper than FTDI.

Thank you for help.

just keep in your mind that USB need (@ host side) a driver and it's a real pleasure time to developp a "Windows driver model" one... (ironic :D)

so the real complete solution I use is FTDI, cause don't matter of how windows manage usb part....
with USB : just
#include "ftd2xx.h"

and use window.h function to link your code to ftdi dll :

ptr_on_dll = LoadLibrary("Ftd2xx.dll");

then :
ptr_usb_Open = (PtrToOpen)GetProcAddress(ptr_on_dll, "FT_Open");

That's really easy... :)

You are wrong Maziar, FTDI products are low end full speed, but it's true they are expensive.

FTDI test circuit

hello friends,

I´ve already bought a FT232AM chip and made a serial-usb converter test board to test this IC. The hardware seems to be ok but I simply cant install it in win98. I´ve contacted FTDI and sent tehm my sch, they told me the hardware was ok but they told me also that win98 had problems with drivers and said I had to update the OS and install some drivers. I´ve done all they said but still not working... Any suggestions??? The IC seems to be very good, expensive but good...

regards,

2000

I use W2K and works fine... If you want to ship up that WIN98 OS... W2K would be a good choice. :)
