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 2 Vendor-Command Support to Implement a USB-to-I C Bridge Features Firmware upgrade of an external ASSP connected to HX3 USB-IF Certified Hub, TID 330000060, 30000074 through USB In-System Programming (ISP) of the EEPROM connected to Supports up to Four USB 3.0-Compliant DS ports HX3 through USB All ports support SS (5 Gbps), and are backward-compatible Extensive Configuration Support with HS (480 Mbps), FS (12 Mbps), and LS (1.5 Mbps) Pin-strap configuration for the following functions: SS and USB 2.0 Link Power Management (LPM) Vendor ID (VID) Dedicated Hi-Speed Transaction Translators (Multi-TT) LED status indicators suspend, SS, and USB 2.0 operation Charging support for each DS port Number of active ports Shared Link for Embedded Applications Number of non-removable devices Each DS port can simultaneously connect to an embedded SS device and a removable USB 2.0 device Ganged or individual power switch enables for DS ports Enables up to eight device connections Power switch polarity selection 2 Custom configuration modes supported with eFuse, I C Enhanced Battery Charging 2 EEPROM, or I C slave Each DS port complies with the USB Battery Charging v1.2 SS and USB 2.0 PHY parameters (BC v1.2) specification Product ID (PID)/VID, manufacturer, and product string Ghost Charge: Each DS port can emulate a Dedicated descriptors Charging Port (DCP) when the host is not connected to the US port Swap DP/DM signals for flexible PCB routing Accessory Charger Adapter Dock (ACA-Dock): Enables Software Features charging and simultaneous data transfer for a smart phone or a tablet acting as a host compliant to BC v1.2 Microsoft WHQL-certified for Windows XP/Vista/7/8/8.1 Apple charging supported on all DS ports Compatible with Mac OS 10.9 and Linux kernel version 3.11 Customize configuration parameters with the easy-to-use Integrated ARM Cortex-M0 CPU Cypresss Blaster Plus software tool 16 KB RAM, 32 KB ROM Flexible Packaging Options Configure GPIOs for overcurrent protection, power enable, and LEDs 68-pin QFN (8 8 1.0 mm) 2 Upgrade firmware using (a) I C EEPROM or (b) an external 88-pin QFN (10 10 1.0 mm) 2 I C master 100-ball BGA (6 6 1.0 mm) Industrial temperature range (40 C to +85 C) Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 +1-408-943-2600 Document Number: 001-73643 Rev. *T Revised April 30, 2019
