1 / 57 page  2010 - 2015 Microchip Technology Inc. DS00001692C-page 1 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. Highlights • 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 • MultiTRAKTM - High-performance multiple transaction trans- lator which provides one transaction transla- tor per port • PortMap - Flexible port mapping and disable sequenc- ing • PortSwap - Programmable USB differential-pair pin loca- tions ease PCB design by aligning USB sig- nal lines directly to connectors • PHYBoost - Programmable USB signal drive strength for recovering signal integrity using 4-level driv- ing strength resolution Features • 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- age • Onboard 24 MHz crystal driver or external 24 MHz clock input • Customizable vendor ID, product ID, and device ID • 4 kilovolts of HBM JESD22-A114F ESD protection (powered and unpowered) • Supports self- or bus-powered operation • Supports the USB Battery Charging specification Rev. 1.1 for Charging Downstream Ports (CDP) • 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 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 USB251xB/xBi USB 2.0 Hi-Speed Hub Controller |
