Overview
CYUSB330x/CYUSB331x CYUSB332x/CYUSB230x 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 ❐ F...
