USB5537B 7-Port SS/HS USB Hub Controller PRODUCT FEATURES The SMSC USB5537B hub is a 7-port SuperSpeed/HiSpeed, low-power, configurable hub controller family fully compliant with the USB Specification. The USB5537B supports 5 Gbps SuperSpeed SS , 480 Mbps Hi-Speed HS , 12 Mbps Full-Speed FS and Mbps Low-Speed LS USB signalling for complete coverage of all defined USB operating speeds. The USB5537B supports legacy USB speeds through its USB hub controller. The new SuperSpeed hub controller available on 4 of the 7 ports operates in parallel with the USB controller, so the 5 Gbps SuperSpeed data transfers are not affected by the slower USB traffic. The USB5537B supports battery charging on a per port basis. On battery charging enabled ports, the devices provide automatic USB data line handshaking. The handshaking supports USB Charging Downstream Port CDP , Dedicated Charging Port DCP and legacy devices. The USB5537B is configured for operation through internal default settings, where custom configurations are supported through an on-chip OTP ROM, an external SPI ROM, or SMBus.

USB5537B 7-Port SS/HS USB Hub Controller

PRODUCT FEATURES

The SMSC USB5537B hub is a 7-port SuperSpeed/HiSpeed, low-power, configurable hub controller family fully compliant with the USB Specification. The USB5537B supports 5 Gbps SuperSpeed SS , 480 Mbps Hi-Speed HS , 12 Mbps Full-Speed FS and Mbps Low-Speed LS USB signalling for complete coverage of all defined USB operating speeds.

The USB5537B supports legacy USB speeds through its USB hub controller. The new SuperSpeed hub controller available on 4 of the 7 ports operates in parallel with the USB controller, so the 5 Gbps SuperSpeed data transfers are not affected by the slower USB traffic.

The USB5537B supports battery charging on a per port basis. On battery charging enabled ports, the devices provide automatic USB data line handshaking. The handshaking supports USB Charging Downstream Port CDP , Dedicated Charging Port DCP and legacy devices.

The USB5537B is configured for operation through internal default settings, where custom configurations are supported through an on-chip OTP ROM, an external SPI ROM, or SMBus.

All LED and port control signal pins are under firmware control in order to allow for maximum operational flexibility those pins can also be configured as GPIOs.
- USB compliant 5 Gbps, 480 Mbps, 12 Mbps and Mbps operation, USB pins are 5 V tolerant

Integrated termination and pull-up/pull-down resistors
- Four downstream USB ports - Three additional USB ports for use cases where

SS is not required

Datasheet
- Supports battery charging of most popular battery powered devices
- Emulates portable/handheld native wall chargers

Charging profiles emulate a handheld device’s wall charger to enable fast charging minutes vs. hours
- Enables charging from a mobile platform that is off - Support tablets’ high current requirements - Optimized for low-power operation and low thermal
dissipation - Vendor Specific Messaging VSM support for
firmware upload over USB - Configuration via OTP ROM, SPI ROM, or SMBus - On-chip 8051 µC manages GPIOs, VBUS, and other
hub signals - 8 K RAM, 32 K ROM - One Time programmable OTP ROM 8 kbit

Includes on-chip charge pump
- Single 25 MHz XTAL or clock input for all on-chip PLL and clocking requirements
- Supports JTAG boundary scan - PHYBoost USB

Selectable drive strength for improved signal integrity
- VariSense USB
controls the receiver sensitivity enabling four programmable levels of USB signal receive sensitivity
- IETF RFC 4122 compliant 128-bit UUID

Software Features
- Compatible with Microsoft Windows 7, Vista, XP, Mac OSX10.4+, and Linux Hub Drivers
- LEDs configuration dependent

Multi color LED scheme vividly shows port capability and operating speed

Embedded 8051 Micro controller for Hub configuration
- Standard hub I/O port power, over-current sense, LEDs are GPIOs controlled by a µC instead of hard coded functions to allow for flexibility for OEM differentiation
