General Description

HT1670 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 4096 patterns

(128 segments and 32 commons). It also supports four

data bits interface, buzzer sound, Watchdog Timer or

time base timer functions. The HT1670 is a memory

mapping and multi-function LCD controller. Since the

HT1670 can control TN-type (Twisted Nematic) or

STN-type (Super Twisted Nematic) LCDs. The software

configuration feature of the HT1670 make it suitable for

multiple LCD applications including LCD modules and

display subsystems. Only six lines (CS,WR, DB0~DB3)

are required for the interface between the host controller

and the HT1670.

Applications

· Leisure products

· Games

· Personal digital assistant

· Cellular phone

· Global positioning system

· Consumer electronics
