The signals are arranged in functional groups according to their associated interface. The “n” symbol in the signal name indicates that the active, or asserted state occurs when the signal is at a low voltage level. When “n” is not present before the signal name, the signal is asserted when 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” signal. The term assert, 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 SYMBOL PIN Descriptions 128-PIN VTQFP BUFFER TYPE DESCRIPTION CompactFlash (In True IDE mode) INTERFACE CF_nCS1 61 O8PU CF Chip Select 1: This pin is the active low chip select 1 signal for the CF ATA device.

SM/xD_PWR SD/MMC_PWR CLK_SEL[1:0] 79 44 92 93 I/O8 I/O8 I/O8 SM / xD Card Power drive of 3.3V @ 100mA. SD / MMC Card Power drive of 3.3V @ 200mA. Clock Select: These pins will select the maximum clock rate that the interface will operate at. Table 5.1 CLK_SEL[1:0] Assignments CLK_SEL1 X 0 1 CLK_SEL0 1 0 0 CLOCK RATE SD/MMC and MS max clock is 15Mhz SD/MMC max clock is 48Mhz; MS clock is set normally SD/MMC max clock is 24Mhz; MS clock is set normally nRESET 115 IS RESET input: This active low signal is used by the system to reset the chip. The active low pulse should be at least 1μs wide. nTEST[1:0] 95 96 I TEST input: These signals are used for testing the chip. User should normally tie them high externally, if the test function is not used.

Hot-insertion capable card connectors are required for all flash media. It is required for SD connector to have Write Protect switch. This allows the chip to detect MMC card. VDD18 (Pin 106) and VDD18PLL (Pin 101) must have a 10uF +/-20% Low-ESR (equivalent series resistance)
