ultra fast usb 2.0 hub and multi-format flash media controller with dual sd interfaces datasheet smsc usb2660/usb2660i 7 revision 1.1 (11-05-10) datasheet chapter 1 overview the smsc usb2660/usb2660i is an integrated usb 2.0 compliant, hi-speed hub, card reader, and protocol converter combo solution. this combo so lution supports today?s popular multi-format flash media cards. this multi-format flash media controller and usb hub combo features two exposed downstream usb ports available for external peripheral expansion. the dedicated flash media reader/writer is internally attached to a third do wnstream port of the hub as a usb compound device which supports the following two interfaces: one in terface is multiplexed for xd-picture card, memory stick, secure digital/multimediacard, and sd/secure digital input/output. the other interface is dedicated to a second sd card slot for sdio bridging applications. sdio bridging is possible with custom firmware. the usb2660/usb2660i will attach to an upstream port as a full-speed hub or as a full-/hi-speed hub. the 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. all required resistors on the usb ports are integrated into the hub. this includes all series termination resistors on d+ and d? pins and all required pull-down and pull-up resistors. the over- current sense inputs for the downstream facing ports have internal pull-up resistors. the usb2660/usb2660i includes programmable features such as: portmap which provides flexible port mapping and di sable sequences. the downstream ports of a usb2660/usb2660i hub can be reordered or disabled in any sequence to support multiple platform designs with minimum effort. for any port that is disabled, the usb26 60/usb2660i automatically reorders the remaining ports to match the usb host controller?s port numbering scheme. portswap which adds per-port programmability to usb differential- pair pin locations. portswap allows direct alignment of usb signals (d+/d-) to connectors avoiding uneven trace length or crossing of the usb differential signals on the pcb. phyboost which enables four programmable levels of usb signal drive strengths in downstream port transceivers. phyboost attempts to restore usb signal integrity. the diagram on the right shows an example of hi-speed usb eye diagrams before (phyboost at 0%) and after (phyboost at 12%) signal integrity restoration in a compromised system environment.

ultra fast usb 2.0 hub and multi-format flash media controller with dual sd interfaces datasheet smsc usb2660/usb2660i 15 revision 1.1 (11-05-10) datasheet chapter 6 pin descriptions this section provides a detailed description of each signal. the signals are arranged in functional groups according to their associated interface. the pin descriptions below are applied when using the internal default firmware and can be referenced in chapter 8, "configuration options," on page 29 . please reference chapter 2, "acronyms," on page 10 for a list of the acronyms used. the ?n? symbol in the signal name indicates that th e active, or asserted, state occurs when the signal is at a low voltage level. when ?n? is not present in the signal name, the signal is asserted at a high voltage level. the terms assertion and negation are used exclusively. this is done to avoid confusion when working with a mixture of ?active low? and ?active high? signals. the term asser t, or assertion, indicates that a signal is active, independent of whether that level is represented by a high or low voltage. the term negate, or negation, indicates that a signal is inactive. 6.1 usb2660/usb2660i pin descriptions table 6.1 usb2660/usb2660i pin descriptions symbol 64-pin qfn buffer type ( ta b l e 6 . 2 ) description secure digital interface sd1_d[7:0] 27 28 31 38 40 41 25 26 i/o8pu secure digital data 7-0 these are the bi-directional data signals sd_d0 - sd_d7 with weak pull-up resistors. sd1_clk 29 o8 secure digital clock this is an output clock signal to the sd/mmc device. sd1_cmd 32 i/o8pu secure digital command this is a bi-directional signal that connects to the cmd signal of the sd/mmc device. the bi-directional signal has a weak internal pull-up resistor. gpio15 / sd1_ncd 22 i/o6 this general purpose pin may be used either as input, edge sensitive interrupt input, or output. custom firmware is required to activate this function. i/o8pu secure digital card detect gpio this is a gpio designated by the default firmware as the secure digital card detection pin and has an internal pull-up.
