IntroductionILI9340L is a 262,144-color single-chip SOC driver for a-TFT liquid crystal

27、 display with resolution of240RGBx320 dots, comprising a 720-channel source driver, a 320-channel gate driver, 172,800 bytes GRAM for graphic display data of 240RGBx320 dots, and power supply circuit.ILI9340L supports parallel 8-/9-/16-/18-bit data bus MCU interface, 6-/16-/18-bit data bus RGB inter

28、face , 3-/4- line serial peripheral interface (SPI) and 2 lane SPI data transmission. The moving picture area can be specified in internal GRAM by window address function. The specified window area can be updated selectively,so that moving picture can be displayed simultaneously independent of still

29、 picture area.ILI9340L can operate with 1.65V 3.3V I/O interface voltage and an incorporated voltage follower circuit to generate voltage levels for driving an LCD. ILI9340L supports full color, 8-color display mode and sleep mode for precise power control by software and these features make the ILI

30、9340L an ideal LCD driver for medium or small size portable products such as digital cellular phones, smart phone, MP3 and PMP where long battery lifeis a major concern.2.FeatureswDisplay resolution: 240xRGB(H) x 320(V)Output:w720 source outputs320 gate outputsCommon electrode output (VCOM)wwa-TFT L
