MMCSD0_ D14 I/O/Z VDD MMCSD0: DATA1 DATA1 MMCSD0_ B13 I/O/Z VDD MMCSD0: DATA2 DATA2 MMCSD0_ A14 I/O/Z VDD MMCSD0: DATA3 DATA3 MMCSD1_ MMCSD1: Clock CLK/ C15 I/O/Z VDD GIO: GIO[024] GIO024 MMCSD1_ MMCSD1: Command CMD/ A17 I/O/Z VDD GIO: GIO[023] GIO023 MMCSD1_ DATA0/ MMCSD1: DATA0 GIO019/ A18 I/O/Z VDD GIO: GIO[019] UART2_T UART2: Transmit data XD MMCSD1_ DATA1/ MMCSD1: DATA1 GIO020/ B15 I/O/Z VDD GIO: GIO[020] UART2_R UART2: Receive data XD MMCSD1_ DATA2/ MMCSD1: DATA2 GIO021/ A16 I/O/Z VDD GIO: GIO[021] UART2_C UART2: CTS TS MMCSD1_ DATA3/ MMCSD1: DATA3 GIO022/ B16 I/O/Z VDD GIO: GIO[022] UART2_R UART2: RTS TS 2.10 Universal Serial Bus (USB) Interface The Universal Serial Bus (USB) interface supports the USB2.0 High-Speed protocol and includes dual-role Host/Slave support. However, no charge pump is included. Table 2-13. USB Terminal Functions TERMINAL TYPE(1) OTHER(2) (3) DESCRIPTION NAME NO. USB D+ (differential signal pair). USB_DP A7 A I/O/Z VDDA33_USB When USB is not used, this signal should be connected to VSS_USB. USB D- (differential signal pair). USB_DM A6 A I/O/Z VDDA33_USB When USB is not used, this signal should be connected to VSS_USB. USB reference current output Connect to VSS_USB_REF via 10K ohm , 1% resistor placed as close to the device USB_R1 C7 A I/O/Z as possible. When USB is not used, this signal should be connected to VSS_USB. (1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal. (2) Specifies the operating I/O supply voltage for each signal. See Section 5.3 , Power Supplies for more detail. (3) PD = pull-down, PU = pull-up. (To pull up a signal to the opposite supply rail, a 1 k Ω resistor should be used.) 30 Device Overview Copyright © 2007–2010, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TMS320DM355 |
