External Signal Description
2.1
Device Pin Assignment
Table 3 shows the pin assignment for the MPR084. For a more detailed description of the functionality of each pin, refer to the
appropriate chapter.
The two packages available for the MPR084 are a 5x5mm 16 pin QFN and a 4x5mm 16 pin TSSOP. Both of the packages and
their respective pinouts are shown in Figure 3.

2.2
Recommended System Connections
The MPR084 Capacitive Touch Sensor Controller requires ten external passive components. When connecting the MPR084 in
a touch sensor system, the electrode lines must have pull-up resistors. The recommended value for these pull-ups is 780k
.
Some electrode arrays will require higher or lower values depending on the application.
In addition to the 8 resistors a bypass capacitor of 1F should always be used between the VDD and VSS lines.and a 4.7
k
pull-up resistor should be included on the IRQ.
