Xplained Pro LCD 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 touchcontroller. The connector pin-out definition is shown in
Connector" on page
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 designs and can be used as a reference.
