HX3 USB 3.0 Hub
HX3 USB 3.0 Hub
General Description
HX3 is a family of USB 3.0 hub controllers compliant with the USB 3.0 specification revision 1.0. HX3 supports SuperSpeed (SS),
Hi-Speed (HS), Full-Speed (FS), and Low-Speed (LS) on all the ports. It has integrated termination, pull-up, and pull-down resistors,
and supports configuration options through pin-straps to reduce the overall BOM of the system.
HX3 includes the following Cypress-proprietary features:
Shared Link™: Enables extra downstream (DS) ports for on-board connections in embedded applications
Ghost Charge™: Enables charging of devices connected to the DS ports when no host is connected on the upstream (US) port
HX3 USB 3.0 Hub
Features
■ USB-IF Certified Hub, TID# 330000060, 30000074
■ Supports up to Four USB 3.0-Compliant DS ports
❐ All ports support SS (5 Gbps), and are backward-compatible
with HS (480 Mbps), FS (12 Mbps), and LS (1.5 Mbps)
❐ SS and USB 2.0 Link Power Management (LPM)
❐ Dedicated Hi-Speed Transaction Translators (Multi-TT)
❐ LED status indicators – suspend, SS, and USB 2.0 operation
■ Shared Link™ for Embedded Applications
❐ Each DS port can simultaneously connect to an embedded
SS device and a removable USB 2.0 device
❐ Enables up to eight device connections
■ Enhanced Battery Charging
❐ Each DS port complies with the USB Battery Charging v1.2
(BC v1.2) specification
❐ Ghost Charge™: Each DS port can emulate a Dedicated
Charging Port (DCP) when the host is not connected to the
US port
❐ Accessory Charger Adapter Dock (ACA-Dock): Enables
charging and simultaneous data transfer for a smart phone
or a tablet acting as a host compliant to BC v1.2
❐ Apple charging supported on all DS ports
■ Integrated ARM® Cortex™-M0 CPU
❐ 16 KB RAM, 32 KB ROM
❐ Configure GPIOs for overcurrent protection, power enable,
and LEDs
❐ UI2pCgmraadsetefirrmware using (a) I2C EEPROM or (b) an external
■ Vendor-Command Support to Implement a USB-to-I2C Bridge
❐ Firmware upgrade of an external ASSP connected to HX3
through USB
❐ In-System Programming (ISP) of the EEPROM connected to
HX3 through USB
■ Extensive Configuration Support
