General Description
HT16220 is a peripheral device specially designed for
I/O type MCU used to expand the display capability. The
max. display segment of the device are 256 patterns
(32´8). It also supports 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
including LCD modules and display subsystems. Only
three lines are required for the interface between the
host controller and the HT16220. The HT162X series
have many kinds of products that match various applica-
tions.
