15 / 159 page ![]() ST7713 Ver 1.6 2008-05 15 6. Pin description 6.1 Power supply pin Name I/O Description Count Connect pin VDD I Power supply for analog, digital system and booster circuit. 5 VDD VDDI I Power supply for I/O system. 6 VDDI AGND I System ground for analog system and booster circuit. 9 GND DGND I System ground for I/O system and digital system. 10 GND 6.2 Interface logic pin Name I/O Description Count Connect pin P68 I -8080/6800 MCU interface mode select. -P68=’1’, select 6800 MCU parallel interface. -P68=’0’, select 8080 MCU parallel interface. -If not used, please fix this pin at VDDI or DGND level. 1 DGND/VDDI IM0~IM2 I -Selection for MCU parallel interface or serial interface. -If not used, please fix this pin at VDDI or DGND level. 3 DGND/VDDI 4WSPI I -When in serial interface, this pin can be used to choose 3-line or 4-line SPI. -If not used, please fix this pin at DGND level. 1 DGND/VDDI RESX I -This signal will reset the device and it must be applied to properly initialize the chip. -Signal is active low. 1 MCU CSX I -Chip selection pin -Low enable. 1 MCU D/CX (SCL) I -Display data/command selection pin in MCU interface. -D/CX=’1’: display data or parameter. -D/CX=’0’: command data. -In serial interface, this is used as SCL. -If not used, please fix this pin at VDDI or DGND level. 1 MCU RDX (E) I -Read enable in 8080 MCU parallel interface. -Read/write operation enable pin in 6800 MCU parallel interface. -If not used, please fix this pin at VDDI or DGND level. 1 MCU WRX (D/CX) I -Write enable in MCU parallel interface. -In 4-line serial interface, this pin is used as D/CX (data/ command selection). -If not used, please fix this pin at VDDI or DGND level. 1 MCU SDA I -When RCM1, RCM0=’1X’ (RGB interface), this pin is used as serial input/output pin. -When RCM1, RCM0=’0X’ (MCU interface), this pin is not used and please connect to VDDI or DGND level. The serial input/output pin in MCU interface mode is D0. 1 MCU DGND/VDDI OSC O -Monitoring pin of internal oscillator clock and is turned ON/OFF by S/W command. -When this pin is inactive (function OFF), this pin is DGND level. -If not used, please open this pin. 1 - D[17:0] I/O -When RCM=”1” (RGB interface), D[17:0] are used as RGB interface data bus. -When RCM=”0” (MCU interface), D[17:0] are used as MCU parallel interface data bus. -D0 is the serial input/output signal in serial interface mode. -In serial interface, D[17:1] are not used and should be connected to VDDI or DGND. 18 MCU TE O -Tearing effect output pin to synchronies MCU to frame rate, activated by S/W command. -If not used, please open this pin. 1 MCU PCLK I -Pixel clock signal in RGB interface mode. -If not used, please fix this pin at VDDI or DGND level. 1 RGB interface VS I -Vertical sync. signal in RGB interface mode. -If not used, please fix this pin at VDDI or DGND level. 1 RGB interface HS I -Horizontal sync. signal in RGB interface mode. -If not used, please fix this pin at VDDI or DGND level. 1 RGB interface DE I -Data enable signal in RGB interface mode. -If not used, please fix this pin at VDDI or DGND level. 1 RGB interface Note1. When in parallel mode, no use data pin must be connected to “1” or “0”. Note2. When CSX=”1”, there is no influence to the parallel and serial interface. |
