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 ❐ 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 ❐ Microsoft WHQL-certified for Windows XP/Vista/7/8/8.1 ❐ Compatible with Mac OS 10.9 and Linux kernel version 3.11 ❐ Customize configuration parameters with the easy-to-use Cypress’s “Blaster Plus” software tool ■ Flexible Packaging Options ❐ 68-pin QFN (8 × 8 × 1.0 mm) ❐ 88-pin QFN (10 × 10 × 1.0 mm) ❐ 100-ball BGA (6 × 6 × 1.0 mm) ❐ Industrial temperature range (–40 °C to +85 °C) |
