ILI9340 is a 262,144-color single-chip SOC driver for a-TFT liquid crystal display with resolution of 240RGBx320
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.
ILI9340 supports parallel 8-/9-/16-/18-bit data bus MCU interface, 8-/16-/18-bit data bus RGB interface and
3-/4-line serial peripheral interface (SPI). 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 picture area.
ILI9340 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. ILI9340 supports full color, 8-color display mode and sleep mode for
precise power control by software and these features make the ILI9340 an ideal LCD driver for medium or small
size portable products such as digital cellular phones, smart phone, MP3 and PMP where long battery life is a
major concern.
