USB5534

4-Port SuperSpeed USB

Hub Controller

General Description

The SMSC USB5534 hub is a 4-port, low-power,

configurable Hub Controller fully compliant with the USB

3.0 Specification. The USB5534 supports 5 Gbps

SuperSpeed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps

Full-Speed (FS) and 1.5 Mbps Low-Speed (LS) USB

signalling for complete coverage of all defined USB

operating speeds.

The USB5534 supports the legacy USB speeds through

its USB 2.0 hub controller. The new SuperSpeed hub

controller operates in parallel with the USB 2.0

controller, so the 5 Gbps SuperSpeed data transfers are

not affected by the slower USB 2.0 traffic.

The USB5534 is configured for operation through

internal default settings, where custom configurations

are supported through an on-chip OTP ROM or an

external SPI ROM.

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.

Features

1.5 Mbps operation, USB pins are 5 V tolerant

—

Integrated termination and pull-up/pull-down resistors

Four downstream USB 3.0 ports (which also support

USB 2.0)

Optimized for low-power operation and low thermal

dissipation

Configuration via OTP ROM or SPI ROM

On-chip 8051 µC manages GPIOs, VBUS, and other

hub signals

TRUESpeed 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
