Why choose EZ-USB™ HX2G3

  • One hub family, many designs: with multiple US:DS port options across consumer/industrial, dock and automotive designs
  • Lower BOM and simpler hardware: with integrated Cortex®‑M0+ (32 KB RAM/ROM), programmable USB2 PHYs, plus hub cascade clock-out
  • Faster bring-up: with configurability via HX2G3 utility; boot from ROM or load FW/config via USB CDC to EEPROM/SPI, or via I²C from an external master
  • Dock-ready PD support hooks: dynamic upstream selection control, integrated Billboard, and container ID/UUID over I²C"

EZ-USB™ HX2G3 DVK

KIT_HX2G3_235X_40QFN is USB 2.0 based development kit to develop EZ-USB™ HX2G3 based consumer hub applications. It enables hub functional testing (both Hi-speed and Full-Speed), USB-IF internal compliance tests, and supports bus-power and self-power mode operation. The kit currently includes CYUSB2354-40LTXI (HX2G3) device in fixed 1:4 port config. 

Quick Start Guide and User Guide are available for easy bringup. For any technical queries related to the kit, contact us through Infineon support case.
