General Description
HT16270 is a peripheral device specially de-
signed for I/O type mC used to expand the dis-
play capability. The max. display segment of
the device are 1024 patterns (64´16). It also
supports serial interface, buzzer sound, watch-
dog timer or time base timer functions. The
HT16270 is a memory mapping and
multi-function LCD controller. The software
configuration feature of the HT16270 make it
suitable for multiple LCD applications includ-
ing LCD modules and display subsystems. Only
three lines are required for the interface be-
tween the host controller and the HT16270.
The HT162X series have many kinds of prod-
ucts that match various applications.
