I am looking for a USB3 peripheral controller that will interface to a PCIe (1 lane) interface. I know about the PLX USB3380 & USB3382 devices. Does anyone know of other alternatives? Al

The PLX devices are c). I'm not aware of anything that does a) or b). Theo

I think you want something that is a USB 3.0 'dual role device' - don't know a part, but I know the Synopsys IP supports this. Or use a microcontroller like a Cypress EZ-FX3, and hook it up to a native bus (or PCIe via a bridge). Theo

Most of these will be obsolete by now, but the manufacturers may have newer parts to replace them. - Renesas/NEC μPD720200 (2xUSB3) - Fresco Logic FL1009 (2xUSB3) - VIA Labs VL800/801 (4/2xUSB3) - TI TUSB7340/7320 (4/2xUSB3) - ASMedia ASM1042 (4xUSB3) - Etron EJ168 (2xUSB3) Of these, I've only used the Renesas parts in products. They seemed to work ok (once the "correct" microcode became available - we got this by purchasing a PCIe board at a local computer shop and desoldering the EEPROM.). Less archaic devices have the firmware onboard and will be easier to use. See also: Pericom, Moschip. Regards, Allan

This is a big list but my needs are for the device end. I suppose a part that supports USB3 OTG would work. I have found lots of host controllers and hubs but only the PLX part for the peripheral side.

It only handles the USB3 side of things, so you would need other logic (possibly an FPGA) to convert to PCIe. http://www.ftdichip.com/Products/ICs/FT600.html Regards, Allan

Would then need some kind of PCIe bridge to parallel. Thx Al
