ILI9325说明文档

　　ILI9325 is a 262，144-color one-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 RAM for graphic data

　　of 240RGBx320 dots， and power supply circuit.

　　ILI9325 has four kinds of system interfaces which are i80-system MPU interface （8-/9-/16-/18-bit bus width），

　　VSYNC interface （system interface + VSYNC， internal clock， DB［17:0］）， serial data transfer interface （SPI）

　　and RGB 6-/16-/18-bit interface （DOTCLK， VSYNC， HSYNC， ENABLE， DB［17:0］）。

　　In RGB interface and VSYNC interface mode， 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.

　　ILI9325 can operate with 1.65V I/O interface voltage， and an incorporated voltage follower circuit to generate

　　voltage levels for driving an LCD. The ILI9325 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 ILI9325 an ideal LCD driver for

　　medium or small size portable products such as digital cellular phones， smart phone， PDA and PMP where

　　long battery life is a major concern.
