CYUSB2304 Datasheet | Cypress

Description HX3 is a family of USB 3.0 hub controllers pliant with the USB 3.0 specification revision 1.0. HX3 supports Super Speed (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-pliant DS ports - All ports support SS (5 Gbps), and are backward-patible 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 plies 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 pliant 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 - UI2p Cgmraadsetefirrmware using (a) I2C EEPROM or (b) an external - Vendor-mand Support to Implement a USB-to-I2C Bridge - Firmware upgrade of an external ASSP connected to HX3 through USB - In-System Programming (ISP) of...
