HydraUSB3 V1 is an open source developer kit for the WCH CH569 MCU to experiment with streaming / high-speed protocols like HSPI and SerDes through USB3. It allows to test and discover the MCU main features, like:

• USB3 SS built-in PHY (5Gbps) and USB2 built-in PHY FS/LS/HS (480Mbps)
  • Can be used as Device or Host.
  • HydraUSB3 dedicated test firmware support USB2 HS and USB3 SS (in a transparent way) basic/bare metal stack in Device Bulk mode with Burst for USB3 Super Speed best performances.
    • HydraUSB3 example firmware support streaming/transfer (with libusb) at more than 330Mbytes/s (from HydraUSB3 to PC Host) and more than 250Mbytes/s (from PC Host to HydraUSB3).
    • HydraUSB3 test firmware for USB2 & USB3 does not requires any driver for Windows (using native WinUSB WCID descriptors in firmware) or GNU/Linux and is supported with libusb open source example codes.
• High Speed Parallel Interface (HSPI) up to 3.8Gbps with unique fast bidirectional parallel bus 8, 16 & 32bits up to 120MHz
  • Can be interfaced with an FPGA to be used as USB3 Super Speed / HSPI bridge.
  • Can be used to interface two HydraUSB3 boards for ultra fast communication/transfer of data.
• SerDes (up to 1.20Gbps officially, up to 1.38Gbps non officially)
  • Can be interfaced with an FPGA to be used as USB3 Super Speed / SerDes bridge.
  • Can be used to interface two HydraUSB3 boards for ultra fast communication or output some traces in real-time with latency < 1us.
• eMMC / SDCard (up to 96MHz 8bits mode with option/extension) Can be used over USB3 SS for ultra fast communication/transfer of data.

HydraUSB3 V1 Evaluation Board / Dev Kit and test firmware are not linked to HydraBus v1 hardware/firmware projects and will not replace it.

HydraUSB3 support natively dual board connection (without requiring any wire/cable except for SerDes connection which requires 2 wires for GXP/GXM)

• The aim is to connect two HydraUSB3 V1 boards together (one on top of another) for multi CPU communication / special streaming features and to use the different supported protocols between 2 boards (one board can act as device and the other as host with the help of PB24 jumper to identify host or device…).
