USB251xB/xBi

USB 2.0 Hi-Speed Hub Controller

General Description

Features

The Microchip USB251xB/xBi hub is a family of low-

power, configurable, MTT (multi transaction translator)

hub controller IC products for embedded USB solu-

tions. The x in the part number indicates the number of

downstream ports available, while the B indicates bat-

tery charging support. The Microchip hub supports low-

speed, full-speed, and hi-speed (if operating as a hi-

speed hub) downstream devices on all of the enabled

downstream ports.

• USB251xB/xBi products are fully footprint com-

patible with USB251x/xi/xA/xAi products as direct

drop-in replacements

—

Cost savings include using the same PCB

components and application of USB-IF Compliance

by Similarity

• Full power management with individual or ganged

power control of each downstream port

• Fully integrated USB termination and pull-up/pull-

down resistors

Highlights

• Supports a single external 3.3 V supply source;

internal regulators provide 1.2 V internal core volt-

age

• High performance, low-power, small footprint hub

controller IC with 2, 3, or 4 downstream ports

• Onboard 24 MHz crystal driver or external

24 MHz clock input

• Fully compliant with the USB 2.0 Specification [1]

• Enhanced OEM configuration options available

through either a single serial I²C EEPROM, or

SMBus slave port

• Customizable vendor ID, product ID, and device

• 4 kilovolts of HBM JESD22-A114F ESD protection

(powered and unpowered)

• MultiTRAK^TM

- High-performance multiple transaction trans-

lator which provides one transaction transla-

tor per port

• Supports self- or bus-powered operation

• Supports the USB Battery Charging specification

Rev. 1.1 for Charging Downstream Ports (CDP)

• PortMap

• The USB251xB/xBi offers the following packages:

- 36-pin SQFN (6x6 mm) (Preferred)

- 36-pin QFN (6x6 mm) (Legacy)

- Flexible port mapping and disable sequenc-

ing

• PortSwap

• USB251xBi products support the industrial tem-

perature range of -40ºC to +85ºC

- Programmable USB differential-pair pin loca-

tions ease PCB design by aligning USB sig-

nal lines directly to connectors

• USB251xB products support the extended com-

mercial temperature range of 0ºC to +85ºC

• PHYBoost

- Programmable USB signal drive strength for

recovering signal integrity using 4-level driv-

ing strength resolution

Applications

• LCD monitors and TVs

• Multi-function USB peripherals

• PC motherboards

• Set-top boxes, DVD players, DVR/PVR

• Printers and scanners

• PC media drive bay

• Portable hub boxes

• Mobile PC docking

• Embedded systems
