Pin Configuration
| PIN | NAME | DIRECTION, TYPE | ACTIVE LEVEL | DESCRIPTION |
|---|---|---|---|---|
| 1 | GND | Ground | N/A | Ground |
| 2 | GND | Ground | N/A | Ground |
| 3 | CPEN | Output, CMOS | High | External 5 volt supply enable. This pin is used to enable the external Vbus power supply. The CPEN pin is low on POR. |

Table 3.1 USB3300 Pin Definitions 32-Pin QFN Package (continued)
| PIN | NAME | DIRECTION, TYPE | ACTIVE LEVEL | DESCRIPTION |
|---|---|---|---|---|
| 4 | VBUS | I/O, Analog | N/A | VBUS pin of the USB cable. The USB3300 uses this pin for the Vbus comparator inputs and for Vbus pulsing during session request protocol. |
| 5 | ID | Input, Analog | N/A | ID pin of the USB cable. For non-OTG applications this pin can be floated. For an A-Device ID = 0. For a B-Device ID = 1. |
| 6 | VDD3.3 | Power | N/A | 3.3V Supply. A 0.1μF bypass capacitor should be connected between this pin and the ground plane on the PCB. |
| 7 | DP | I/O, Analog | N/A | D+ pin of the USB cable. |
| 8 | DM | I/O, Analog | N/A | D- pin of the USB cable. |
| 9 | RESET | Input, CMOS | High | Optional active high transceiver reset. This is the same as a write to the ULPI Reset , address 04h, bit 5. This does not reset the ULPI register set. This pin includes an integrated pull-down resistor to ground. If not used, this pin can be floated or connected to ground (recommended). See Section 6.1.11, "Reset Pin" for details. |
| 10 | EXTVBUS | Input, CMOS | High | External Vbus Detect. Connect to fault output of an external USB power switch or an external Vbus Valid comparator. See Section 6.5.4, "External Vbus Indicator," on page 44 for details. This pin has a pull down resistor to prevent it from floating when the ULPI bit UseExternalVbusIndicator is set to 0. |
| 11 | NXT | Output, CMOS | High | The PHY asserts NXT to throttle the data. When the Link is sending data to the PHY, NXT indicates when the current byte has been accepted by the PHY. The Link places the next byte on the data bus in the following clock cycle. |
| 12 | DIR | Output, CMOS | N/A | Controls the direction of the data bus. When the PHY has data to transfer to the Link, it drives DIR high to take ownership of the bus. When the PHY has no data to transfer it drives DIR low and monitors the bus for commands from the Link. The PHY will pull DIR high whenever the interface cannot accept data from the Link, such as during PLL start- up. |
| 13 | STP | Input, CMOS | High | The Link asserts STP for one clock cycle to stop the data stream currently on the bus. If the Link is sending data to the PHY, STP indicates the last byte of data was on the bus in the previous cycle. The STP pin also includes the interface protection detailed in Section 6.1.9.3, "Interface Protection," on page 36 . |
| 14 | CLKOUT | Output, CMOS | N/A | 60MHz reference clock output. All ULPI signals are driven synchronous to the rising edge of this clock. |
| 15 | VDD1.8 | Power | N/A | 1.8V for digital circuitry on chip. Supplied by On-Chip Regulator when REG_EN is active. Place a 0.1μF capacitor near this pin and connect the capacitor from this pin to ground. Connect pin 15 to pin 26. |
