UTC101AF-GAC$ is a 10.1" IPS TFT LCD with 1280*RGB*800 resolution.

It is a trasmissive normally Black TFT with 4-Wire SPI Interface.

Controller IC used in TFT is RA8877

UTC101AF-GAC$ supports Capacitive Touch Panel


The RA8877 is a low power color LCD Controller with support for up to 512M-bits external SDRAM memory. The RA8877 supports an 8/16-bit asynchronous parallel host bus while providing high performance bandwidth into the external display memory allowing for fast screen updates. The RA8877 also provides support for multiple display buffers, Picture-in-Picture, Opacity control, and display rotation/mirror … etc.
