ultra fast usb 2.0 multi-format, sd/mmc, and ms flash media controllers datasheet smsc usb224x 19 revision 2.0 (10-14-09) 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 are applied when using the internal default firmware and can be referenced in chapter 7, "pin configurations," on page 25 . please reference chapter 2, "acronyms," on page 7 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 the 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 usb224x 36-pin qfn pin descriptions table 6.1 usb224x 36-pin qfn pin descriptions symbol usb2240/40i usb2241/41i usb2242/42i usb2244/44i buffer type description xd-picture card (xd) interface (a pplies only to usb2240/usb2240i) xd_d[7:0] 20 23 25 30 4 5 7 8 i/o12pd xd data these bi-directional data signals have weak internal pull-down resistors. xd_nwp 9 o12pd xd write protect this pin is an active low write protect signal for the xd device and has a weak pull-down resistor that is permanently enabled. xd_ale 10 o12pd xd address strobe this pin is an active high address latch enable signal for the xd device and has a weak pull-down resistor that is permanently enabled. xd_cle 11 o12pd xd command strobe this pin is an active high command latch enable signal for the xd device and has a weak pull-down resistor that is permanently enabled.
