USB251xB/xBi USB 2.0 Hi-Speed Hub Controller PRODUCT FEATURES Data Brief General Description Features The SMSC USB251xB/xBi hub is a family of low-power, configurable, MTT (multi transaction translator) hub controller IC products for embedded USB solutions. The x in the part number indicates the number of downstream ports available, while the B indicates battery charging support. The SMSC hub supports lowspeed, full-speed, and hi-speed (if operating as a hispeed 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 Enhanced OEM configuration options available through either a single serial I2C® EEPROM, or SMBus slave port MultiTRAKTM — High-performance multiple transaction translator which provides one transaction translator per port PortMap PortSwap — Flexible port mapping and disable sequencing — Programmable USB differential-pair pin locations ease PCB design by aligning USB signal lines directly to connectors PHYBoost — Cost savings include using the same PCB components and application of USB-IF Compliance by Similarity Highlights — Programmable USB signal drive strength for recovering signal integrity using 4-level driving strength resolution USB251xB/xBi products are fully footprint compatible with USB251x/xi/xA/xAi products as direct drop-in replacements Full power management with individual or ganged power control of each downstream port Fully integrated USB termination and pull-up/pulldown resistors Supports a single external 3.3 V supply source; internal regulators provide 1.2 V internal core voltage 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 package: — 36-pin QFN (6x6 mm) lead-free RoHS compliant package USB251xBi products support the industrial temperature range of -40ºC to +85ºC USB251xB products support the extended commercial 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 SMSC USB251xB/xBi Revision 2.2 (02-17-12) PRODUCT PREVIEW USB 2.0 Hi-Speed Hub Controller Order Number(s): ORDER NUMBERS* USB2512B-AEZG USB2513B-AEZC USB2514B-AEZC USB2512Bi-AEZG USB2513Bi-AEZG USB2514Bi-AEZG LEAD-FREE ROHS COMPLIANT PACKAGE PACKAGE SIZE (MM) TEMPERATURE RANGE 0ºC to 85ºC 36-QFN 6x6x0.5 -40ºC to 85ºC *Add -TR to the end of any QFN order number to order tape and reel (36-pin packages only).
