INTRODUCTION
2.1
General Description
The Microchip USB5906 hub is a low-power, OEM configurable, USB 3.1 Gen 1 hub controller with 6 downstream ports
and advanced features for embedded USB applications. The USB5906 is fully compliant with the Universal Serial Bus
Revision 3.1 Specification and USB 2.0 Link Power Management Addendum. The USB5906 supports 5 Gbps Super-
Speed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) USB downstream
devices on all enabled downstream ports.
The USB5906 supports the legacy USB speeds (HS/FS/LS) through a dedicated USB 2.0 hub controller that is the cul-
mination of five generations of Microchip hub controller design and experience with proven reliability, interoperability,
and device compatibility. The SuperSpeed hub controller operates in parallel with the USB 2.0 hub controller, decoupling
the 5 Gbps SS data transfers from bottlenecks due to the slower USB 2.0 traffic.
The USB5906 hub feature controller enables OEMs to configure their system using “Configuration Straps.” These straps
simplify the configuration process, assigning default values to USB 3.1 Gen 1 ports and GPIOs. OEMs can disable ports,
enable battery charging, and define GPIO functions as default assignments on power-up, removing the need for OTP
or external SPI ROM.
The USB5906 supports downstream battery charging via the integrated battery charger detection circuitry, which sup-
ports the USB-IF Battery Charging (BC1.2) detection method and most Apple devices. The USB5906 provides the bat-
tery charging handshake and supports the following USB-IF BC1.2 charging profiles:
• DCP: Dedicated Charging Port (Power brick with no data)
• CDP: Charging Downstream Port (1.5A with data)
• SDP: Standard Downstream Port (0.5A with data)
• Custom profiles loaded via SMBus or OTP
Additionally, the USB5906 includes many powerful and unique features such as:
The Hub Feature Controller, which provides an internal USB device dedicated for use as a USB to I
2
C/UART/SPI/
GPIO interface, allowing external circuits or devices to be monitored, controlled, or configured via the USB interface.
PortSwap, which adds per-port programmability to USB differential-pair pin locations. PortSwap allows direct alignment
of USB signals (D+/D-) to connectors to avoid uneven trace length or crossing of the USB differential signals on the
PCB.
PHYBoost, which provides programmable levels of Hi-Speed USB signal drive strength
in the downstream port transceivers. PHYBoost attempts to restore USB signal integrity
in a compromised system environment. The graphic on the right shows an example of
Hi-Speed USB eye diagrams before and after PHYBoost signal integrity restoration. in
a compromised system environment.
VariSense, which controls the USB receiver sensitivity enabling programmable levels of USB signal receive sensitivity.
This capability allows operation in a sub-optimal system environment, such as when a captive USB cable is used.
Port Split, which allows for the USB3.1 Gen1 and USB2.0 portions of downstream ports 5 and 6 to operate inde-
pendently and enumerate two separate devices in parallel in special applications.
USB Power Delivery Billboard Device, which allows an internal device to enumerate as a Billboard class device when
a Power Delivery Alternate Mode negotiation has failed. The Billboard device will enumerate temporarily to the host PC
when a failure occurs, as indicated by a digital signal from an external Power Delivery controller.
The USB5906 can be configured for operation through internal default settings. Custom OEM configurations are sup-
ported through external SPI ROM or OTP ROM. All port control signal pins are under firmware control in order to allow
for maximum operational flexibility, and are available as GPIOs for customer specific use.
The USB5906 is available in commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. An internal
block diagram of the USB5906 is shown in
Figure 2-1

Power and Ground Pin Descriptions
The “_N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage
level. For example, RESET_N indicates that the reset signal is active low. When “_N” is not present after the signal
name, the signal is asserted when at the high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of
“active low” and “active high” signal. The term assert, or assertion, indicates that a signal is active, independent of
whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inac-
tive.
