Figure 6. Pin Mapping Of The Aek-Usb-2Typec1 Connectors; Table 1. Aek-Usb-2Typec1 4X20 Connector Interface Board Pin Descriptions - ST AEKD-USBTYPEC1 User Manual

Connectors CN1 (4x20 male pin connector) and CN2 (2x9 male pin connector) are located on the opposite side of
the USB Type-C ports. CN1 is for the control signals and CN2 is for the power supply. In the figure, the green
cells in CN1 represent the pins to drive the external power board. The cell labels starting with "Pxx" represent the
microcontroller ports mapped to the 4x37 connector. The microcontroller ports can assume different functions
depending on the register settings of a specific microcontroller.
The following table contains the descriptions of the interface board pins.
Pin Name
ADC_I_0 ADC channel to convert the current value provided by VBUS on to port 0.
ADC_I_1 ADC channel to convert the current value provided by VBUS on to port 1.
ADC_V_0 ADC channel to convert the voltage value (VBUS) applied to port 0.
ADC_V_1 ADC channel to convert the voltage value (VBUS) applied to port 1.
ALERT_0 Alert pin of STUSB1702Y device managing port 0
ALERT_1 Alert pin of STUSB1702Y device managing port 1
(1)
LED01 To command the LED "ROLE" for port0
(2)
LED11 To command the LED "ROLE" for port1
LED02 To command the LED "VBUS" for port0
