BTC070BA-GBR$ is a 7.0" TFT LCD with 800*RGB*480 resolution.

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

Controller IC used in TFT is RA8873

RA8873 is a low-cost color for small and medium size TFT LCD controller, and support 64M-bits external SDRAM memory. The RA8873 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 RA8873 also provides support for multiple display buffers, Picture-in-Picture, Opacity control, and display rotation/mirror.
