USB5537B 7-Port SS/HS USB Hub Controller PRODUCT FEATURES Datasheet General Description Supports battery charging of most popular battery powered devices The SMSC USB5537B hub is a 7-port SuperSpeed/Hi- USB-IF Battery Charging rev. 1.2 support (DCP & CDP) Speed, low-power, configurable hub controller family Apple Portable product charger emulation fully compliant with the USB 3.0 Specification. The Blackberry charger emulation USB5537B supports 5 Gbps SuperSpeed (SS), Chinese YD/T 1591-2006 charger emulation 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS) and Chinese YD/T 1591-2009 charger emulation Supports additional portable devices 1.5 Mbps Low-Speed (LS) USB signalling for complete Emulates portable/handheld native wall chargers coverage of all defined USB operating speeds. Charging profiles emulate a handheld devices wall The USB5537B supports legacy USB speeds through its charger to enable fast charging (minutes vs. hours) USB 2.0 hub controller. The new SuperSpeed hub Enables charging from a mobile platform that is off controller (available on 4 of the 7 ports) operates in Support tablets high current requirements parallel with the USB 2.0 controller, so the 5 Gbps Optimized for low-power operation and low thermal dissipation SuperSpeed data transfers are not affected by the Vendor Specific Messaging (VSM) support for slower USB 2.0 traffic. firmware upload over USB The USB5537B supports battery charging on a per port Configuration via OTP ROM, SPI ROM, or SMBus basis. On battery charging enabled ports, the devices On-chip 8051 C manages GPIOs, VBUS, and other provide automatic USB data line handshaking. The hub signals handshaking supports USB 1.2 Charging Downstream 8K RAM, 32 K ROM One Time programmable (OTP) ROM: 8 kbit Port (CDP), Dedicated Charging Port (DCP) and legacy Includes on-chip charge pump devices. Single 25 MHz XTAL or clock input for all on-chip PLL The USB5537B is configured for operation through and clocking requirements internal default settings, where custom configurations Supports JTAG boundary scan are supported through an on-chip OTP ROM, an PHYBoost (USB 2.0) Selectable drive strength for improved signal integrity external SPI ROM, or SMBus.
