General Description
HT16220 is a peripheral device specially de-
signed for I/O type
C used to expand the dis-
play capability. The max. display segment of
the device are 256 patterns (32 8). It also sup-
ports serial interface, buzzer sound, watchdog
timer or time base timer functions. The
HT16220 is a memory mapping and
multi-function LCD controller. The software
configuration feature of the HT16220 make it
suitable for multiple LCD applications includ-
ingLCDmodulesanddisplaysubsystems.Only
three lines are required for the interface be-
tween the host controller and the HT16220.
The HT162X series have many kinds of prod-
ucts that match various applications.
