DS00001715C-page 3 USB3813 1.0 INTRODUCTION The USB3813 is a low-power, OEM configurable, MTT (Multi-Transaction Translator) USB 2.0 hub controller with 3 downstream ports and advanced features for embedded USB applications. The USB3813 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 3port 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 USB3813 has been specifically optimized for mobile embedded applications. The pin-count has been reduced by optimizing the USB3813 for mobile battery-powered embedded systems where power consumption, small package size, and minimal BOM are critical design requirements. Standby mode power has been minimized and reference clock inputs can be aligned to the customer’s specific mobile application. Flexible power rail options ease integration into energy efficient designs by allowing the USB3813 to be powered in a single-source (VBUS, VBAT, 3.3V) or a dualsource (VBAT + 1.8, 3.3V + 1.8) configuration. 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 USB3813 supports both upstream battery charger detection and downstream battery charging. The USB3813 integrated 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 USB3813 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 USB3813 provides an additional USB endpoint dedicated for use as a USB to I2C/SPI interface, allowing external circuits or devices to be monitored, controlled, or configured via the USB interface. Additionally, the USB3813 includes many powerful and unique features such as: FlexConnect, which provides flexible connectivity options. The USB3813’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 fullspeed data throughput regardless of the number of active downstream connections. MultiTRAKTM outperforms conventional 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 USB3813 hub can be reordered or disabled in any sequence to support multiple platform designs with minimum effort. For any port that is disabled, the USB3813 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 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. 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. The USB3813 is available in commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature range versions.

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” signals. 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 inactive. Note: The buffer type for each signal is indicated in the BUFFER TYPE column of Table 3-1. A description of the buffer types is provided in Section 3.3.
