We have been using the low speed CY7C63833 device in our product but needed to migrate to full-speed USB and so chose the CY7C64316 device. I have since realised that the programming pins are no longer shared with D+/- as they were in the low speed device. Is there any full-speed devices that share P1.0 and P1.1 with the USB D+/- ? Or am I stuck with having to program them using an additional connector? I haven't come across any in my searches.

Kind Regards,

 i just checked that we do not have any full speed devices which share the USB lines with the programming lines. I guess the converter is a good solution. Some of our devices have a USB bootloader which can help you bootload the USB  firmware.
