MT3000 Capacitive Controller Reference Guide 10
Overview of the MT3000 Touchscreen Controller
The MT3000 touchscreen controller and touchscreen are supplied as a
matched set. A 25-point linearization procedure has been performed to
determine the physical properties of the screen, and the data is stored in the
NovRAM of the controller that ships with the screen.
The controller and touchscreen are shipped mated by the flex cable with a
serialized label on the sensor, the controller, and over the connector to
identify them as a matched set. If the connection needs to be broken during
the integration process, the components can be matched again by serial
number.
The MT3000 is a compact controller with a standard RS-232 serial
interface. It measures 1.3 x 2.4 inches with a total height profile of 0.4
inches from the thru hole pins on the trace side of the board to the top of the
highest component on the opposite side. The MT3000 has a touchscreen
connector, a serial cable connector, and a power connector. Refer to
Figure 1 for connector locations and to Figure 2 for the overall dimensions.
