Interface Pin Function

LCM PIN Definition

NO Symbol Function I/O
1 GND Ground P
2-6 NC No connection -
7 VCI High voltage power supply for analog circuit blocks
(2.5 ~ 3.3 V)		 P
8 IOVCC Low voltage power supply for interface logic circuits
(1.65 ~ 3.3 V)		 P
9 TE Tearing effect output pin to synchronize MPU to frame writing, activated by S/W command. When this pin is not activated, this pin is low.
If not used, open this pin.		 O
10 CS Chip select signal. I
11 D/CX(SCL) (D/CX): This pin is used to select “Data or Command” in the parallel interface.
When DCX = 1, data is selected.
When DCX = 0, command is selected.
(SCL): This pin is used as the serial interface clock in 3-wire
9-bit/4-wire 8-bit serial data interface.
If not used, this pin should be connected to VDDI or VSS.		 I
12 WR(SPI_D/C) (WRX) - 8080-Ⅰ/8080-Ⅱ system: Serves as a write signal and writes data at the rising edge.
(D/CX) - 4-line system: Serves as the selector of command or parameter.
Fix to VDDI level when not in use.		 I
13 RD 8080-Ⅰ/8080-Ⅱ system (RDX): Serves as a read signal and MCU read data at the rising edge.
Fix to VDDI level when not in use.		 I
14-29 DB0~DB15 18-bit parallel bi-directional data bus for MCU system and RGB
interface mode
Fix to VSS level when not in use.		 I/O
30 RESET This signal will reset the device and must be applied to properly initialize the chip.
Signal is active low.		 I
31 IM0 Select the MCU interface mode
IM2 IM1 1M0 MCU-Interface Mode DB Pin in use
Register/Content GRAM
0 0 0 80 MCU 8-bit bus interface I D[7:0] D[7:0]
0 0 1 80 MCU 16-bit bus interface I D[7:0] D[15:0]
0 1 0 80 MCU 9-bit bus interface I D[7:0] D[8:0]
0 1 1 80 MCU 18-bit bus interface I D[7:0] D[17:0]
1 0 1 3-wire 9-bit data serial interface I SDA: In/Out
1 1 0 4-wire 8-bit data serial interface I SDA: In/Out
MPU Parallel interface bus and serial interface select
If use RGB Interface must select serial interface.
* : Fix this pin at VDDI or VSS.		 I
32 IM1
33 IM2
34 DB16 18-bit parallel bi-directional data bus for MCU system and RGB
interface mode
Fix to VSS level when not in use.		 I/O
35 DB17
36 LEDK Cathode of LED backlight. P
37 LEDK Cathode of LED backlight. P
38 LEDA Anode of LED backlight. P
39 SDI(SDA) When IM[3] : Low, Serial in/out signal.
When IM[3] : High, Serial input signal.
The data is applied on the rising edge of the SCL signal.
If not used, fix this pin at VDDI or VSS.		 I/O
40 SDO Serial output signal.
The data is outputted on the falling edge of the SCL signal.
If not used, open this pin		 O
