USB4604

1.0

INTRODUCTION

The USB4604 is a low-power, OEM configurable, MTT (Multi-Transaction Translator) USB 2.0 hub controller with 4

downstream ports and advanced features for embedded USB applications. The USB4604 is fully compliant with the

USB 2.0 Specification, USB 2.0 Link Power Management Addendum, High-Speed Inter-Chip (HSIC) USB Electrical

Specification Revision 1.0, and will attach to an upstream port as a Full-Speed hub or as a Full-/Hi-Speed hub. The 4-

port hub supports Low-Speed, Full-Speed, and Hi-Speed (if operating as a Hi-Speed hub) downstream devices on all of

the enabled downstream (non-HSIC) ports. HSIC ports support only Hi-Speed operation.

The USB4604 has been specifically optimized for embedded systems where high performance, and minimal BOM costs

are critical design requirements. Standby mode power has been minimized and reference clock inputs can be aligned

to the customer’s specific application. Flexible power rail options ease integration into energy efficient designs by allow-

ing the USB4604 to be powered in a single-source (VBUS, VBAT, 3.3V) or a dual-source (VBAT + 1.8, 3.3V + 1.8) con-

figuration. Additionally, all required resistors on the USB ports are integrated into the hub, including all series termination

and pull-up/pull-down resistors on the D+ and D– pins.

The USB4604 supports both upstream battery charger detection and downstream battery charging. The USB4604 inte-

grated battery charger detection circuitry supports the USB-IF Battery Charging (BC1.2) detection method and most

Apple devices. These circuits are used to detect the attachment and type of a USB charger and provide an interrupt

output to indicate charger information is available to be read from the device’s status registers via the serial interface.

The USB4604 provides the battery 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

The USB4604 provides an additional USB endpoint dedicated for use as a USB to I

C/SPI interface, allowing external

circuits or devices to be monitored, controlled, or configured via the USB interface. Additionally, the USB4604 includes

many powerful and unique features such as:

FlexConnect,

which provides flexible connectivity options. The USB4604’s downstream port 1 can be swapped with

the upstream port, allowing master capable devices to control other devices on the hub.

MultiTRAK

™

Technology,

which utilizes a dedicated Transaction Translator (TT) per port to maintain consistent full-

speed data throughput regardless of the number of active downstream connections. MultiTRAK

outperforms conven-

tional USB 2.0 hubs with a single TT in USB full-speed data transfers.

PortMap,

which provides flexible port mapping and disable sequences. The downstream ports of a USB4604 hub can

be reordered or disabled in any sequence to support multiple platform designs with minimum effort. For any port that is

disabled, the USB4604 hub controllers automatically reorder the remaining ports to match the USB host controller’s port

numbering scheme.

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 sig-

nal 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 integ-

rity restoration.

VariSense,

which controls the USB receiver sensitivity enabling programmable lev-

els of USB signal receive sensitivity. This capability allows operation in a sub-optimal

system environment, such as when a captive USB cable is used.

The USB4604 is available in commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature range versions.

As shown in the ordering code matrix, two USB4604 firmware revisions are available: “-1080” and “-1070”. The -1080

version enables the internal Hub Controller, while the -1070 version disables it. There are no additional differences

between these two versions.
