AR1000 SERIES RESISTIVE TOUCH SCREEN CONTROLLER
3.4
5-Wire Touch Sensor Interface
Sensor tail pinouts can vary by manufacturer and part
number. Ensure sensor tail pins for one pair of
diagonally related sensor corners are connected to the
controller’s X-/X+ pins and the tail pins for the other pair
of diagonally related corners are connected to the
controller’s Y-/Y+ pins.
The controller’s X-/X+ and Y-/Y+ pin pairs do not need
to connect to a specific sensor axis. The orientation of
controller pins X- and X+ to the two selected diagonal
sensor corners is not important.
Likewise, the orientation of controller pins Y- and Y+ to
the other two selected diagonal sensor corners is not
important. The sensor tail pin connected to its top layer
must be connected to the controller’s 5WSX- pin.
Connections to a 5-wire touch sensor are shown in
Figure 3-3 below.

Tie unused controller pins SX+, SY-, and SY+ to VSS.
See
and
Section 3.9 “Noise Considerations” for important
information regarding the capacitance of the controller
schematic hardware.
