UTC043BB-EWR$ is a 4.3" TFT LCD with 480*RGB*272 resolution.

It is a trasmissive normally white TFT with parallel Interface.

Controller IC used in TFT is RA8875


RA8875 is a text/graphic mixed display with 2 layers TFT LCD controller. It is designed to meet the requirement of middle size TFT module up to 800x480 pixels with characters or 2D graphic application. Embedded 768KB display RAM provides user a flexible solution for displaying buffer of almost application. Besides, optional external serial flash is capable to provide the up to 32x32pixels font bitmap for BIG5/GB coding. For graphic usage, RA8875 supports a 2D Block Transfer Engine(BTE) that is compatible with 2D BitBLT function for processing the mass data transfer. The advanced geometric speed-up engine provides user an easy way to draw the programmable geometric shape by hardware, like line, square, circle and ellipse. Besides, for different end-user applications, many powerful functions are integrated with RA8875, such as scroll function, floating window display, graphic pattern and font enlargement function. These functions will save user a large of software effort during development period.

5	/WR	H/L	In 8080 series, this pin is used as /WR signal (data write) , active low.
6	/RD	H/L	In 8080 series, this pin is used as /RD signal (Data Read) , active low.
7~14	DB0~DB7	H/L/td>	Data bus line
15	/CS	H/L	Chip Select input, Low active.
16	/RES	H/L	Reset signal
17	WAIT	-	Wait Signal Output This is a WAIT output to indicate the RA8875 is in busy state. The RA8875 can’t access MCU cycle when WAIT pin is active. It is active low and could be used for MCU to poll busy status by connecting it to I/O port.
18	INT	-	Interrupt Signal Output The interrupt output for MCU to indicate the status of RA8875.
19	VLED+	-	Power supply for backlight driver.(3.0~5.0V)
20	VLED-	-	Power supply for backlight driver.(GND)
