DATASHEET

USB 2.0 High-Speed 2-Port Hub Controller

Datasheet

Chapter 2 General Description

The SMSC USB251x hub family is a group of low-power, OEM configurable, MTT (multi transaction translator)1 hub controller IC’s with downstream ports for embedded USB solutions. The SMSC USB251x hub family is fully compliant with the USB 2.0 specification. Each of the SMSC hub controllers can attach to an upstream port as a full-speed hub or as a full-/hi-speed hub. The SMSC hub controllers support low-speed, full-speed, and hi-speed (if operating as a hi-speed hub) downstream devices on all of the enabled downstream ports.

All required resistors on the USB ports are integrated into the hub. This includes all series termination resistors on D+ and D– pins and all required pull-down and pull-up resistors on D+ and D– pins. The over-current sense inputs for the downstream facing ports have internal pullup resistors.

The USB251x hub family includes programmable features such as:

MultiTRAKTM Technology which utilizes a dedicated 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 USB251x hub can be reordered or disabled in any sequence to support multiple platform designs with minimum effort. For any port that is disabled, the USB251x 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 enables 4 programmable levels of USB signal drive strength in downstream port transceivers. PHYBoost attempts to restore USB signal integrity.

OEM Selectable Features

A default configuration is available in each of the SMSC USB251x hub controllers following a reset. This configuration may be sufficient for most applications. Strapping option pins make it possible to modify a sub-set of the configuration options.

The USB251x hub controllers may be configured by an external EEPROM or a microcontroller. When using the microcontroller interface, the hub appears as an SMBus slave device. If the hub is pin-strapped for external EEPROM configuration but no external EEPROM is present, then a value of ‘0’ will be written to all configuration data bit fields (the hub will attach to the host with all ‘0’ values).

The USB251x hub family supports OEM selectable features including:

Optional OEM configuration via I2C EEPROM or via the industry standard SMBus interface from an external SMBus host or microcontroller.

Supports compound devices on a port-by-port basis.

Selectable over-current sensing and port power control on an individual or ganged basis to match the OEM’s choice of circuit board component selection.

Customizable vendor ID, product ID, and device ID.

Configurable delay time for filtering the over-current sense inputs.

Configurable downstream port power-on time reported to the host.

Supports indication of the maximum current that the hub consumes from the USB upstream port.

Supports Indication of the maximum current required for the hub controller.

1.USB2512A/2Ai only uses a single transaction translator.

Chapter 5 Pin Descriptions

This chapter is organized by a set of pin configurations (organized by package type) followed by a corresponding pin list organized alphabetically. A comprehensive and detailed description list of each signal (named in the pin list) is organized by function in Table 5.2, “USB251x Pin Descriptions,” on page 22. Please refer to Table 5.3, “Buffer Type Descriptions,” on page 27 for a list of buffer types.

The “N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When “N” is not present after the signal name, the signal is asserted when it is 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.

UPSTREAM USB 2.0 INTERFACES

 

 

 

 

 

 

 

 

 

USBDM_UP

IO-U

USB Data

 

 

 

USBDP_UP

 

These pins connect to the upstream USB bus data signals (host, port, or

 

 

 

 

 

 

 

 

upstream hub).

 

 

 

 

 

 

 

 

 

VBUS_DET

I/O12

Detect Upstream VBUS Power

 

 

 

 

 

Detects state of Upstream VBUS power. The SMSC hub monitors

 

 

 

 

VBUS_DET to determine when to assert the internal D+ pull-up resistor which

 

 

 

 

signals a connect event.

 

 

 

 

 

When designing a detachable hub, this pin should be connected to VBUS on

 

 

 

 

the upstream port via a 2 to 1 voltage divider.

 

 

 

 

 

For self-powered applications with a permanently attached host, this pin must

 

 

 

 

be connected to 3.3 V (typically VDD33).

 

 

 

 

 

 

 

 

 

 

 

DOWNSTREAM USB 2.0 INTERFACES

 

 

 

 

 

 

 

 

 

USBDP_DN[x:1]/

IO-U

Hi-Speed USB Data

 

 

 

PRT_DIS_P[x:1]

 

These pins connect to the downstream USB peripheral devices attached to

 

 

 

 

 

 

 

 

the hub’s port. To disable, pull up with a 10 K resistor to 3.3 V.

 

 

 

 

 

 

 

 

 

USBDM_DN[x:1]/

 

Downstream Port Disable Strap Option

 

 

 

PRT_DIS_M[x:1]

 

If this strap is enabled by package and configuration settings (see Table 8.1,

 

 

 

 

 

 

 

 

"Hub Configuration Options"), then this pin will be sampled at RESET_N

 

 

 

 

negation to determine if the port is disabled.

 

 

 

 

 

To disable a port, pull up both PRT_DIS_M[x:1] and PRT_DIS_P[x:1] pins

 

 

 

 

corresponding to the port numbers.

 

 

 

 

 

 

 

 

 

PRTPWR[x:1] /

O12

USB Power Enable

 

 

 

 

 

Enables power to USB peripheral devices downstream.

 

 

 

 

 

When PRTPWR_POL pin is unavailable, the hub supports active high power

 

 

 

 

controllers only.

 

 

 

 

 

When PRTPWR_POL pin is available, the active signal level of the PRTPWR

 

 

 

 

pins is determined by the power polarity strapping function of the

 

 

 

 

PRTPWR_POL pin.

 

 

 

 

 

 

 

 

 

BC_EN[x]

IPD

Battery Charging Strap Option

 

 

 

 

 

*This feature is only available on USB251xB/Bi.

 

 

 

 

 

If this strap is enabled by package and configuration settings, (see Table 8.1,

 

 

 

 

"Hub Configuration Options"), this pin will be sampled at RESET_N negation

 

 

 

 

to determine if ports [x:1] support the battery charging protocol (and thus the

 

 

 

 

supporting external port power controllers) that would enable a device to draw

 

 

 

 

the currents per the USB battery charging specification.

 

 

 

 

 

BC_EN[x] = 1: Battery charging feature is supported for port x

 

 

 

 

 

BC_EN[x] = 0: Battery charging feature is not supported for

 

 

 

 

 

port x
