4 Connector Pin Assignment
4.3 Arduino Compatible Connector
The mapping of GPIOs and AURIX™ pin functions to Arduino compatible functions can be found in Figure 7
Mapping of Arduino Functions to AURIX™ Pin Functions. The Arduino compatible connector supports
• SPI interface (SPI_xxx)
• I2C interface (I2C_xxx)
• UART interface (UART_xxx)
• PWM signal outputs (PWM0-13)
• ADC input (ADC0-5)
• Interrupt input (INT0-1)
Note that all pins are cabable of offering more functions than mentioned in Figure 7 Mapping of Arduino
Functions to AURIX™ Pin Functions. For more information about all pin functions, we want to refer you to the
corresponding datasheet.
Figure 7 Mapping of Arduino Functions to AURIX™ Pin Functions
The AURIX™ TCxx4 lite Kit works with 3.3 V logic levels. Therefore, any board that works with 5 V logic levels,
cannot be used.
Analog input signals ADC0-5 are limited to a voltage which is smaller or equal than VAREF with
VAREF = VDDM = 3.3 V. Primarily, ADC0 to ADC5 should be used as analog input, because there is no additional
circuit connected to these pins. Parallel operation of I2C and ADC4 / ADC5 is possible, because they don’t share
anymore the same pins at the Arduino connector X301 and X303 as on previous AURIX™ lite Kit V1.
