4.8 USB 2.0 Interface
On the LaunchPad, a USB 2.0 interface is offered through a USB Type-C connector (J10). the USB DP and DM
signals connect the USB0 port of the SoC through an ESD protection diode. The DP and DM sinals are shorted
to the A and B option for DP and DM on the connector side in order to support the flip action in the cable.
4.9 I2C Interface
The AM243x SoC supports two I2C interfaces that are used to connect BoosterPack headers, test automation
header, LED driver for ethernet LEDs, and Board ID EEPROM to the LaunchPad.
• SoC_I2C0 Interface: SoC_I2C0 is connected to each of the following:
– I2C0 interface is used by the software to identify the LaunchPad through the Board ID memory device
(AT24CM01-XHD-T) which is configured to respond to the address 0x50.
– I2C0 on the LaunchPad is also used to control the 8 bit LED driver (TPIC2810) configured to respond to
address 0x60 which is used to conrol the Industrial LEDs.
– I2C0 is also connected to the BoosterPack (J5.9, J5.10) expansion connector.
• SoC_I2C1 Interface: SoC_I2C1 is connected to each of the following:
– Test automation header (687140183622 from Wurth)
– I2C1 is also connected to the BoosterPack (J1.9, J1.10) expansion connector
