When in I2C mode (see ADDR/ORIENT pin), it is the active LOW open drain interrupt output used to prompt the processor to read the I2C register bits. When the device is in GPIO mode (see ADDR/ORIENT pin), this pin is OUT3, an open drain output LOW = Audio Accessory detected HIGH−Z = Audio Accessory not detected 7 SDA/OUT1 Open Drain I/O 8 SCL/OUT2 Open Drain I/O SDA/OUT1 and SCL/OUT2 are dual function pins. When in I2C mode (see ADDR/ ORIENT pin), SDA/OUT1 is the SDA data signal and SCL/OUT2 is the SCL clock signal of the I2C interface. When the device is in GPIO mode (see ADDR/ORIENT pin), these pins are OUT1 and OUT2 inputs (I) or outputs (O) are shown below: ID pin OUT1 (I/O) OUT2 (I/O) Functionality HIGH−Z HIGH−Z (O) LOW (O) No Device Attached HIGH−Z HIGH−Z (O) HIGH−Z (O) Sink with Default Current HIGH−Z LOW (O) HIGH−Z (O) Sink with 1.5 A Current HIGH−Z LOW (O) LOW (O) Sink with 3 A Current LOW HIGH (I) HIGH (I) Source with Default Current LOW LOW (I) HIGH (I) Source with 1.5 A Current LOW LOW (I) LOW (I) Source with 3 A Current LOW HIGH (I) LOW (I) Reserved (Do Not Use) GPIO PIN INTERFACE 3 PORT/ DEBUG_N Input then Push/Pull Output PORT/DEBUG_N is a dual function pin: 3 state input to set the port role. On the falling edge of EN_N and when VDD is active or during power up when EN_N is LOW, the state of this pin is sampled. This pin is also sampled on a SW_RES soft reset via I2C. HIGH = FUSB303 as a Source Only port Float = FUSB303 as a Dual Role Port (DRP) LOW = FUSB303 as a Sink Only port Note: a 900 kW resistor should be used when connecting to VDD or GND to reduce standby current. Subsequently, this pin is the DEBUG_N push−pull output LOW = Debug Accessory detected HIGH = Debug Accessory not detected 5 ADDR/ ORIENT Input then Push/Pull Output ADDR/ORIENT is a dual function pin: 3 state input to set to I2C mode and the I2C address or for GPIO mode. On the falling edge of EN_N and when VDD is active or during power up when EN_N is LOW, the state of this pin is sampled. This pin is also sampled on a SW_RES soft reset via I2C. HIGH = I2C mode with address 62h Float = GPIO mode LOW = I2C mode with address 42h Note: a 900 kW resistor should be used when connecting to VDD or GND to reduce standby current.

Orientation decoded on this pin after a Sink Debug Test System (DTS) attached to FUSB303. 2. Orientation decoded on this pin after a Source Debug Test System (DTS) attached to FUSB303. High Voltage Tolerance on CCx and VBUS pins will also have ADDR/ORIENT set based on the levels detected for CC1 and CC2. ID will be set LOW. The FUSB303 also supports DRP toggling for detecting debug test systems. When PORT/DEBUG_N= float upon enable, the FUSB303 can detect both Source and Sink debug test systems depending on how it resolves its role as a Source or Sink. Then it acts either as a Source or Sink as described above. The FUSB303 will report Debug Test System detection via the Type I2C register as well. The detection is the same as described above except Source, Sink and DRP roles are configured via the Portrole register. This Portrole register setting has higher priority over the PORT/DEBUG_N pin state for Source/Sink/DRP port role. The FUSB303 will set INT_N/OUT3 = LOW in GPIO mode when an Audio Accessory is detected. The FUSB303 will report Audio Accessory detection via the Type I2C register as well when Audio Accessory detection is configured via the Portrole register. The FUSB303 has additional protection for the type C connector pins where it can tolerate up to 28V on VBUS, CC1 and CC2 to protect against any misbehaving Type C device connect to the FUSB303. If VBUS tolerance is needed higher than 28V, a 900k resistor can be used externally along with a Transient Voltage Suppressor (TVS) to achieve almost any higher voltage tolerance dictated by the TVS chosen. Dead Battery If power is not applied to FUSB303 and it is attached to a Source device, then the Source would pull up the CC line connected through the cable. The FUSB303 in response will turn on the pull−down that will bring the CC voltage to a range that the Source can detect an attached device and turn on VBUS. GPIO Mode, Debug and Audio Accessories When VDD is active and on the trailing edge of EN_N, the FUSB303 will sample PORT/DEBUG_N to determine if the FUSB303 operates as a Source (HIGH), Sink (LOW) or DRP (floating). Subsequently the PORT/DEBUG_N will be set LOW when a Debug Test System is detected. If the FUSB303 is configured as a Sink (PORT/DEBUG_N= LOW upon enable), the FUSB303 will detect a Debug Test System if Rp is detected on both CC1 and CC2. Devices that support orientation detection will also have ADDR/ORIENT set based on the levels detected for CC1 and CC2. ID will be set HIGH−Z. If the device is configured as a Source (PORT/DEBUG_N= HIGH upon enable), the FUSB303 will detect a Debug Test System if Rd is detected on both CC1 and CC2. Devices that support orientation detection FORCE.SNK and FORCE.SRC Functionality In some cases, a device may need to force its role to a Sink or a Source especially if two DRP devices are connected together and they have connected in the wrong device role. In that case, the FUSB303 has incorporated a function that allows it to be forced into either Sink or Source. However, if it cannot complete this role change, the FUSB303 will resume its previous role and flag success or failure with I_FRC_SUCC and I_FRC_FAIL interrupts respectively. Remedial Actions In some cases, a device may start to detect a Source or Sink but get caught in a loop trying to resolve the detected device. In that case the FUSB303 provides functionality to resolve www.onsemi.com 6 FUSB303 as a Sink when attached to another DRP. If connected to another Sink, the port will detach. The threshold at which AUTOSNK can be triggered can be programmed via the AUTO_SNK_TH bits. The I_AUTOSNK interrupt is triggered whenever this functionality is invoked. to a stable attached state. This functionality can be turned on and off via the REMEDY_EN and DCABLE_EN bits. Multiple cases are tried and some of the register settings will be changed to try to achieve stable attach. The I_REMEDY interrupt will allow the processor to know that this functionality has been triggered. Power Up, Initialization and Reset, Interrupt Operation, I2C Interface AUTOSNK Mode The FUSB303 includes a full I2C slave controller. The I2C slave fully complies with the I2C specification version 6 requirements. This block is designed for fast mode. Examples of an I2C write and read sequence are shown Figure 5 and Figure 6 respectively. When the FUSB303 is powered directly from VBAT the AUTO_SNK_EN mode can be used to prevent the application from attaching as a Source when the battery is weak or disconnect and attach as a Sink. With AUTO_SNK_EN enabled the port will attempt to configure 8bits 8bits 8bits S Slave Address WR A Register Address K A Write Data A Write Data K+1 A Write Data K+2 NOTE: A Write Data K+N−1 A P Single byte write is initiated by Master with P immediately following the first data byte and slave A Figure 5.

I2C Write Example When an interruptible event occurs, INT_N/OUT3 is driven LOW and is in a high impedance state again when the processor clears the interrupt by writing a one in the position of the interrupt bit that was set. Subsequent to the initial power up or reset; if the processor writes a “1” to global interrupt mask bit when the system is already powered up, the INT_N/OUT3 pin stays in a high impedance state and ignores all interrupts until the global interrupt mask bit is cleared. If an event happens that would ordinarily cause an interrupt when the global interrupt mask bit is set, the INT_N/OUT3 pin goes LOW when the global interrupt mask is cleared. Interrupt bits hold their value and to clear a specific interrupt, a “1” needs to be written to that interrupt bit. When power is first applied, the FUSB303 will power up in the configuration set by the PORT/DEBUG_N input with Audio Accessory Support enabled and all interrupts masked. If the ADDR/ORIENT input is HIGH or LOW (I2C mode) the local processor can then re−configure the FUSB303 to the desired mode and clear the global interrupt mask bit, INT_MASK using the I2C interface. The INT_N/OUT3 pin is an active LOW, open drain output. This pin indicates to the host processor that an interrupt has occurred in the FUSB303 which needs attention. The INT_N/OUT3 pin is in a high impedance state by default after power−up or device reset, and the global interrupt mask (INT_MASK in Control register) is set. After INT_MASK bit is cleared by the local processor, the INT_N/OUT3 pin stays high impedance in preparation of future interrupts. www.onsemi.com 7 FUSB303 I2C Address The ADDR/ORIENT bit HIGH or LOW is indicated in bit 5 of the slave address shown in Table 4.

If more than one bit is set to 1b simultaneously then an order of priority will be used. First priority is DISABLED, second is ERROR_REC, third is FORCE_SRC, fourth is FORCE_SNK, fifth is UNATT_SRC, last is UNATT_SNK. The highest priority bit will take precedence and all other bits will be cleared automatically. 11. The DISABLED bit must be manually cleared. Also DISABLED bit has a higher priority over Portrole register since the DISABLED bit has to be cleared in order to execute the new Portrole register settings. However, all other Manual register bits don’t have a lot of meaning if the Portrole register is changed and so Portrole register setting should have higher priority than all bits except for DISABLED bit.
