ultra fast usb 2.0 multi-format flash media controller datasheet smsc USB2240/usb2241 13 revision 2.6 (05-08-08) datasheet chapter 5 pin descriptions this section provides a detailed description of each signal. the signals are arranged in functional groups according to their associated interface. 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 be fore 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. 5.1 pin descriptions table 5.1 USB2240/usb2241 36-pin qfn pin descriptions name symbol 36-pin qfn buffer type description xd interface (applies only to USB2240) xd data xd_d[7:0] 20 23 25 30 4 5 7 8 i/o12pd the bi-directional data signal has an internal weak pull-down resistor. xd write protect xd_nwp 9 o12pd this pin is an active low write protect signal for the xd device. this pin has a weak pull-down resistor that is permanently enabled. xd address strobe xd_ale 10 o12pd this pin is an active high address latch enable signal for the xd device. this pin has a weak pull-down resistor that is permanently enabled. xd command strobe xd_cle 11 o12pd this pin is an acti ve high command latch enable signal for the xd device. this pin has a weak pull-down resistor that is permanently enabled. xd read enable xd_nre 16 o12pu this pin is an active low read strobe signal for xd device. when using the internal fet, this pin has an internal weak pull-up resistor that is tied to the output of the internal power fet, and is controlled by the sm_pu bit of the sm_ctl register. if an external fet is used (internal fet is disabled), then the internal pull-up is not available (external pull-ups must be used).
