External Signal Description
2.1
Device Pin Assignment
Table 1 shows the pin assignment for the MPR03X. For a more detailed description of the functionality of each pin, refer to the
appropriate chapter.
The package available for the MPR03X is a 2 x 2 mm 8 pin
DFN. The package and pinout is shown in Figure 3.

Recommended System Connections
The MPR03X Capacitive Touch Sensor Controller requires one external passive component. As shown in Table 1, the REXT line
should have a 75 k
connected from the pin to GND. This resistor needs to be 1% tolerance.
In addition to the one resistor, a bypass capacitor of 10 F should always be used between the VDD and VSS lines and a
4.7 k
pull-up resistor should be included on the IRQ. Note: This condition is when pin 8 is used for interrupt indication and not
for electrode sensing.
The remaining two connections are SCL and SDA. Depending on the specific application, each of these control lines can be used
by connecting them to a host controller. In the most minimal system, the SCL and SDA must be connected to a master I2C
interface to communicate with the MPR03X. All of the connections for the MPR03X are shown by the schematic in Figure 4.
