Description
HD61202 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 HD61202, which is produced in the CMOS
process, can complete portable battery drive
equipment in combination with a CMOS microcontroller,
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 HD61203.
