HD44102 Datasheet | Hitachi Semiconductor

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 microputer 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 bination of HD44102 with a CMOS microcontroller can plete portable battery-driven unit utilizing the liquid crystal display’s low power dissipation. The bination of HD44102 with the row (mon) 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...
