ILI9163C is a 262,144-color one-chip SoC driver for a-TFT liquid crystal display with resolution of 132RGBx162
dots, comprising a 396-channel source driver, a 162-channel gate driver, 8,114bytes G RAM for graphic data of
132RGBx162 dots, and power supply circuit.
The ILI9163C supports 18-/16-/9-/8-bit data bus interface and serial peripheral interfaces (SPI). It also supplies
18-bit, 16-bit or 6-bit RGB interface for driving video signal directly from application controller. 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.
ILI9163C can operate with 1.65V I/O interface voltage, and an incorporated voltage follower circuit to generate
voltage levels for driving an LCD. The ILI9163C also supports a function to display in 8 colors and a sleep mode,
allowing for precise power control by software and these features make the ILI9163C 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.
