USB 3.0 Hub Controller 68-Pin QFN Bulk

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

• USB 3.0-Certified Hub, TID# 330000060
• 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
  • Upgrade firmware using (a) I2C EEPROM or (b) an external I2C master
• 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
  • Pin-strap configuration for the following functions: Vendor ID (VID), Charging support for each DS port Number of active ports, Number of non-removable devices, Ganged or individual power switch enables for DS ports, Power switch polarity selection
  • Custom configuration modes supported with eFuse, I2C EEPROM, or I2C slave: SS and USB 2.0 PHY parameters, Product ID (PID)/VID, manufacturer, and product string descriptors, Swap DP/DM signals for flexible PCB routing
• Software Features
