HD44102

HD44102 (Dot Matrix Liquid Crystal Graphic Display Column Driver) Description The HD44102 is a column (segment) driver for dot matrix liquid crystal graphic display systems, storing the display data transferred from a 4-bit or 8-bit microcomputer in the internal display RAM and generating dot matrix liquid crystal driving signals. Each bit data of display RAM corresponds to on/off state of each dot of a liquid crystal display to provide more flexible than character display. The HD44102 is produced by the CMOS process. Therefore, the combination of HD44102 with a CMOS microcontroller can complete portable battery-driven unit utilizing the liquid crystal display’s low power dissipation. The combination of HD44102 with the row (common) driver HD44103 facilitates dot matrix liquid crystal graphic display system configuration. Features Dot matrix liquid crystal graphic display column driver incorporating display RAM Interfaces with 4-bit or 8-bit MPU RAM data directly displa...
