描述 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.
