HD61202U
(Dot Matrix Liquid Crystal GraphicDisplay Column Driver)
Description
HD61202U is a column (segment) driver for dot matrix liquid crystal graphic display systems. It 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 it 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.
