Multi-Function Display Controller
1
1. General Description
The Realtek RTD2525AR-CG monitor controller combines an analog RGB input interface, a HDMI 1.4a
compliant digital input interface with HDCP1.4, and a DP1.2 digital input interface with HDCP1.4. The
embedded MCU is based on an industrial standard 8051 core with external serial flash.
The RTD2525AR-CG is suitable for multiple market segments and display applications, such as monitor,
All in One PC, and embedded applications.
