NJU6818

NJU6818 80COMMON x 104RGB LCD DRIVER FOR 4,096-COLOR STN DISPLAY ! GENERAL DESCRIPTION The NJU6818 is an 80COMMON x 104RGB LCD driver for 4,096-color STN display. It contains common drivers, RGB drivers, a serial and a parallel MPU interface circuit, an internal LCD power supply, grayscale palettes and 99,840-bit display data RAM. The segment drivers for RGB (Red, Green, Blue) independently produce optimum 16 grayscales from a built-in 32-grayscale palette, and the LSI achieves 4,096 colors (16x16x16). In addition, the NJU6818 operates with a low voltage of 1.7V and a low operating current, therefore it is ideally suited for battery-powered handheld applications. PACKAGE BUMP CHIP !
