This is the Hardware Functional Specification for the RA8871M/73M/76M TFT LCD Controller. RA8871M/73M/76M supports
CMOS type interface (MIPI DPI-2). . Including in this document are system block diagrams, Pin information, AC/DC characteristics, each block’s function description, detail register descriptions, and power mode
control.
RA8871M/73M/76M is a low-cost color TFT LCD controller for the small- and the medium-size panel , the RA8871M/73M/76M
have Buffer RAM . TheRA8871M/73M/76M 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 RA8871M/73M/76M
also provides support for multiple display buffers, Picture-in-Picture, Opacity control, and display
rotation/mirror … etc.
