TFT LCD with Touch Panel
The SAM9M10 features an LCD controller. A 4.3" 480x272 Portrait Mode LCD provides the SAM9M10-
G45-EK with a low power LCD display, back light unit and a touch panel, similar to that used on commer-
cial PDAs.
The TFT LCD component is a truly model number TFT1N4633.
Graphics and text can be displayed on the dot matrix panel with up to 16 million colors by supplying 24-
bit data signals (8bitxRGB by default) or 16-bit data signals (5+6+5bitxRGB in option). This allows the
user to develop graphical user interfaces for a wide variety of end applications.
Warning: never connect/disconnect the LCD display from the board while the power supply is on. Doing
so may damage both units and is not covered by warranty.
The back light voltage is generated from a CP2122ST boost converter. It is powered directly by the VIN
5 VCC power (the control for the back light voltages is separated from the main board voltages due to
the specific voltage requirements of the LCD panel).
