96 / 281 page  DM385, DM388 SPRS821D – MARCH 2013 – REVISED DECEMBER 2013 www.ti.com 3.3.23 USB 3.3.23.1 USB0 Table 3-50. USB0 Terminal Functions SIGNAL NAME [1] DESCRIPTION [2] TYPE [3] AAR BALL [4] USB0_CE USB0 charger enable. When the USB0 PHY is powered O B20 down, this pin should be left unconnected. USB0_DM USB0 bidirectional data differential signal pair I/O B21 [plus/minus]. When the USB0 PHY is powered down, this pin should be left unconnected. USB0_DP USB0 bidirectional data differential signal pair I/O A21 [plus/minus]. When the USB0 PHY is powered down, this pin should be left unconnected. USB0_DRVVBUS USB0 Contoller VBUS Control ouput. When this pin is O K23 used as USB0_DRVVBUS and the USB0 Controller is operating as a Host, this signal is used by the USB0 Controller to enable the external VBUS charge pump. When the USB0 PHY is powered down, this pin should be left unconnected. USB0_ID USB0 identification input. When the USB0 PHY is I A20 powered down, this pin should be left unconnected. USB0_VBUSIN 5-V USB0 VBUS comparator input. This analog input pin I B22 senses the level of the USB VBUS voltage and should connect directly to the USB VBUS voltage. When the USB0 PHY is powered down, this pin should be left unconnected. 3.3.23.2 USB1 Table 3-51. USB1 Terminal Functions SIGNAL NAME [1] DESCRIPTION [2] TYPE [3] AAR BALL [4] USB1_CE USB1 charger enable. When the USB1 PHY is powered O C21 down, this pin should be left unconnected. USB1_DM USB1 bidirectional data differential signal pair I/O B23 [plus/minus]. When the USB1 PHY is powered down, this pin should be left unconnected. USB1_DP USB1 bidirectional data differential signal pair I/O A23 [plus/minus]. When the USB1 PHY is powered down, this pin should be left unconnected. USB1_DRVVBUS USB1 Contoller VBUS Control ouput. When this pin is O AF31 used as USB1_DRVVBUS and the USB1 Controller is operating as a Host, this signal is used by the USB1 Controller to enable the external VBUS charge pump. When the USB1 PHY is powered down, this pin should be left unconnected. USB1_ID USB1 identification input. When the USB1 PHY is I A24 powered down, this pin should be left unconnected. USB1_VBUSIN 5-V USB1 VBUS comparator input. This analog input pin I B24 senses the level of the USB VBUS voltage and should connect directly to the USB VBUS voltage. When the USB1 PHY is powered down, this pin should be left unconnected. 96 Device Pins Copyright © 2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: DM385 DM388 |
