General Description

HT1650 is a peripheral device specially designed for I/O

type MCUs which are used to expand the display capa-

bility. The max. display segment of the device are 2048

patterns (64 segments and 32 commons). It also sup-

ports four data bits interface, buzzer sound, Watchdog

Timer or time base timer functions. The HT1650 is a

memory mapping and multi-function LCD controller. It

can control TN-type (Twisted Nematic) or STN-type

(Super Twisted Nematic) LCDs. The software configu-

ration feature of the HT1650 make it suitable for multiple

LCD applications including LCD modules and display

subsystems. Only six lines (CS, WR, DB0~DB3) are re-

quired for the interface between the host controller and

the HT1650.
