Description
The ILI9225 is a 262,144-color one-chip SoC driver for a-TFT liquid crystal display with resolution of 176RGBx220 dots, comprising a 528-channel source driver, a 220-channel gate driver, 87120 bytes RAM for graphic data of 176RGBx220 dots, and power supply circuit. ILI9225 has four kinds of system interfaces which are i80/M68-system MPU interface (8-/9-/16-/18-bit bus width), serial data transfer interface (SPI) and RGB 6-/16-/18-bit interface (DOTCLK, VSYNC, HSYNC, ENABLE, DB[17:0]). In RGB interface, the combined use of high-speed RAM write function and widow address function enables to display a moving picture at a position specified by a user and still pictures in other areas on the screen simultaneously, which makes it possible to transfer display the refresh data only to minimize data transfers and power consumption.
