General Description

HT1626 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 768 patterns

(48

´16). It also supports serial interface, buzzer sound,

Watchdog Timer or time base timer functions. The

HT1626 is a memory mapping and multi-function LCD

controller. The software configuration feature of the

HT1626 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 HT1626. The HT162X series

have many kinds of products that match various applica-

tions.
