Figure 8 Mapping of Arduino Functions to XMC
The XMC4700 Relax Kit for 5V Shields features bi-directional voltage level shifter and therefor supports 5 V
Arduino shields. Jumper JP300 (IOREF) determines whether the Arduino shield is driven with 5 V or 3.3 V.
Analog input signals ADC0-5 are limited to 3.3 V input voltage. Primarily ADC0 to ADC3 should be used as analog
input, because there is no additional circuit connected to these pins, whereas ADC4 and ADC5 have additional
circuitry and require an input signal with lower input impedance.
Note: Parallel operation of I2C and ADC4 / ADC5 is not possible, because they share the same Arduino pins.

User Push Buttons and User LEDs

The XMC4700/XMC4800 Relax Kit Series-V1 provides two push buttons and two LEDs. The port pins used can be
found in Table 3 and Table
devices or connectors.
