MTCH6301 Projected Capacitive Touch Controller
Description:
MTCH6301 is a turnkey projected capacitive controller
that allows easy integration of multi-touch and gestures
to create a rich user interface in your design. Through
a sophisticated combination of Self and Mutual
Capacitive scanning for both XY screens and touch
pads, the MTCH6301 allows designers to quickly and
easily integrate projected capacitive touch into their
application.
Applications:
• Human-Machine Interfaces with Configurable
Button, Keypad or Scrolling Functions

5.7 Example Custom Application
Layout
An example 4RX/11TX sensor is shown in Figure 5-3.
In addition to using a completely modified pin layout,
this example differs from the default configuration by
also having the TX axis along the bottom (X) and RX
axis along the side (Y). Note that some RX pins are
also used as TX lines in this example.

The resulting scaling coefficient for the custom
application example is shown in Table 5-3. The scaling
coefficients were derived using Table 5-2.

Using Figure 5-2, the Flip State register should be set
to ‘0b110’ or 0x6.
The Pin Map register array for this particular setup is set
as follows:
RX Pin Map: {3,2,1,0}
TX Pin Map: {15,16,31,32,33,34,22,8,5,23,24}
