General Description

HT1622 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

HT1622 is a memory mapping and multi-function LCD

controller. The software configuration feature of the

HT1622 make it suitable for multiple LCD applications in-

cluding LCD modules and display subsystems. Only

three lines are required for the interface between the host

controller and the HT1622. The HT162X series have

many kinds of products that match various applications.
