USB2512A USB 2.0 Hi-Speed 2-Port Hub Controller PRODUCT FEATURES Data Brief General Description T h e S M S C 2 - P o r t H u b i s a l o w p o w e r, O E M configurable, STT (Single transaction translator) hub controller IC with 2 downstream ports for embedded USB solutions. The 2-port hub is fully compliant with the USB 2.0 Specification and will attach to an upstream port as a Full-Speed Hub or as a Full-/Hi-Speed Hub. The 2-Port 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. General Features -- Select Downstream Ports as Non-Removable Ports Hub Controller IC with 2 downstream ports Enhanced OEM configuration options available through either a single serial I2C EEPROM, or SMBus Slave Port 36-pin (6x6mm) QFN lead-free, RoHS compliant package Hardware Features Select the presence of a permanently hardwired USB peripheral device on a port by port basis Configure the delay time for filtering the over-current sense inputs Configure the delay time for turning on downstream port power Indicate the maximum current that the 2-port hub consumes from the USB upstream port Indicate the maximum current required for the hub controller Pin Selectable Options for Default Configuration Applications Low power operation Full Power Management with individual or ganged power control of each downstream port On-chip Power On Reset (POR) Internal 1.8V Voltage Regulator Fully integrated USB termination and Pull-up/Pulldown resistors On Board 24MHz Crystal Driver, Resonator or External 24MHz clock input Enhanced EMI rejection and ESD protection performance LCD monitors and TVs Multi-function USB peripherals PC mother boards Set-top boxes, DVD players, DVR/PVR Printers and scanners PC media drive bay Portable hub boxes Mobile PC docking Embedded systems OEM Selectable Features Customizable Vendor ID, Product ID, and Device ID Select whether the hub is part of a compound device (When any downstream port is permanently hardwired to a USB peripheral device, the hub is part of a compound device) Flexible port mapping and disable sequence. Ports can be disabled/reordered in any order to support multiple product SKUs. Hub will automatically reorder the remaining ports to match the Host controller's numbering scheme. Programmable USB differential-pair pin location. Ease PCB layout by aligning USB signal lines directly to connectors Programmable USB signal drive strength. Recover USB signal integrity due to compromised system environment using 2-level driving strength resolution SMSC USB2512A PRODUCT PREVIEW Revision 1.96 (07-11-08) USB 2.0 Hi-Speed 2-Port Hub Controller ORDER NUMBER: USB2512A-AEZG FOR 36 PIN, QFN LEAD-FREE ROHS COMPLIANT PACKAGE 80 ARKAY DRIVE, HAUPPAUGE, NY 11788 (631) 435-6000, FAX (631) 273-3123 Copyright (c) 2008 SMSC or its subsidiaries.
