Description

HD61202U is a column (segment) driver for dot matrix liquid crystal graphic display systems. HD61202U stores the display data transferred from a 8-bit micro controller in the internal display RAM and generates dot matrix liquid crystal driving signals.

Each bit data of display RAM corresponds to on/off state of a dot of a liquid crystal display to provide more flexible than character display. As HD61202U is internally equipped with 64 output drivers for display, it is available for liquid crystal graphic displays with many dots.

The HD61202U, which is produced in the CMOS process, can complete portable battery drive equipment in combination with a CMOS micro-controller, utilizing the liquid crystal display's low power dissipation. Moreover it can facilitate dot matrix liquid crystal graphic display system configuration in combination with the row (common) driver HD61203U.
