3.2.2. Xplained Pro LCD Extension Connector
The LCD connector provides the ability to connect to display extensions that have a parallel interface.
The connector implements signals for a MCU parallel bus interface and a LCD controller interface as well
as signals for a touch controller. The connector pin-out definition is shown in
Table 3-3 Xplained Pro LCD
Connector on page 9. Note that usually only one display interface is implemented, either the LCD
controller or the MCU bus interface.
A FPC/FFC connector with 50 pins and 0.5mm pitch is used for the LCD connector. The connector
XF2M-5015-1A from Omron is used on several Xplained Pro designs and can be used as a reference.
