Interface Pin Function Pin Symbol Level Direction Function 1 GND 0v - Ground. Must be connected to an external ground. 2-3 VLOGIC I/O 3.3v I Digital Logic Supply and Input/Output Supply 4-5 VANALOG +3.3v I Analog Supply 6 IM0 - I IM2 IM1 IM0 Interface Mode DB Pins in Use Parallel (also known as DOTCLK or DPI) Interface 0 0 0 18-Bit RGB / DPI DB17-BD0 0 0 1 9-Bit RGB / DPI DB8-DB0 0 1 0 16-Bit RGB / DPI DB15-BD0 0 1 1 8-Bit RGB / DPI DB7-BD0 3 or 4-Wire SPI 1 0 1 3-Wire, 9-Bit SPI SDI, SCL, CS 1 1 1 4-Wire, 8-Bit SPI SDI, SCL, CS, RS NOTE: If pin is not used, tie to GND or make no connection. DPI = Display Pixel Interface 7 IM1 8 IM2 9 RST L I Reset Signal Pin. Low: Display controller is reset. The RST pin should be pulsed low shortly after power is applied. High: The RST pin should be brought high (VLOGIC I/O) for normal operation. 10 VSYNC - I Vertical and Horizontal Frame Synchronizing Signal used for RGB / DPI Mode. When not used, pin should be pulled high (VLOGIC I/O). 11 HSYNC 12 PCLK H/L I Pixel Clock Signal for RGB / DPI Mode. When not used, pin should be pulled low. 13 DE H/L I/O Data Enable Signal for RGB / DPI Mode. When not used, pin should be pulled low. 14-31 DB17-DB0 H/L I/O In MIPI Data Bus Interface Mode, DB7-DB0 are used as follows: • 18-Bit Bidirectional Data Bus. • 8-Bit Bus: use DB7-DB0 • 9-Bit Bus: use DB8-DB0 • 16-Bit Bus: use DB15-DB0 • 18-Bit Bus: use DB17-DB0 In MIPI DPI Interface Mode, DB17-DB0 are treated as 18-Bit Bus. RGB Data Bus: • 6-Bit Bus: use DB5-DB0 • 16-Bit Bus: use DB15-DB0 • 18-Bit Bus: use DB17-DB0 If not used, connect to VSSD. 32 GND 0v - Parallel data bus. (Notice the descending order.) 33 MISO - O SPI Data Signal. (MISO = Master In Slave Out) 34 MOSI - I SPI Data Signal. (MOSI = Master Out Slave In) 35 RD - I DBI Type-B: Serves as a read signal and read data at the low level. If not used, tie to VLOGIC I/O- |
