USB 2.0 Hi-Speed Hub Controller
General Description
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.
• High performance, low-power, small footprint hub
controller IC with 2, 3, or 4 downstream ports
• 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
- High-performance multiple transaction trans-
lator which provides one transaction transla-
tor per port
- Flexible port mapping and disable sequenc-
- Programmable USB differential-pair pin loca-
tions ease PCB design by aligning USB sig-
nal lines directly to connectors
- Programmable USB signal drive strength for
recovering signal integrity using 4-level driv-
ing strength resolution
• 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
• Supports a single external 3.3 V supply source;
internal regulators provide 1.2 V internal core volt-
• Onboard 24 MHz crystal driver or external
24 MHz clock input
• Customizable vendor ID, product ID, and device
• 4 kilovolts of HBM JESD22-A114F ESD protection
(powered and unpowered)

• The USB251xB/xBi offers the following packages:
- 36-pin SQFN (6x6 mm) (Preferred)
- 36-pin QFN (6x6 mm) (Legacy)
• USB251xBi products support the industrial tem-
perature range of -40ºC to +85ºC
• USB251xB products support the extended com-
mercial temperature range of 0ºC to +85ºC
• 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

You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000).
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for cur-
rent devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the
revision of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site;
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include -literature number) you are
