General Description

HT1647 is a peripheral device specially de-

signed for I/O type mC used to expand the dis-

play capability. The max. display segment of

the device are 1024 patterns (64 segments and

16 commons). It also supports four data bits in-

terface, buzzer sound, Watchdog Timer or time

base timer functions. The HT1647 is a memory

mapping and multi-function LCD controller.

Since the HT1647 can control ECB-type (Elec-

trically Controlled Birefringence) LCDs in ad-

dition to current TN-type (Twisted Nematic) or

STN-type (Super Twisted Nematic) LCDs, it

can support 4-color display as well as 4-level

gray scale display. It displays 4-level gray scale

output when HT1647 drives TN-type,

STN-type LCDs. It displays four color output

when HT1647 drives ECB-type. HT1647 uses

PWM (Pulse Width Modulation) technique. The

software configuration feature of the HT1647

make it suitable for multiple LCD applications

including LCD modules and display subsys-

tems. Only six lines (CS, WR, DB0~DB3) are

required for the interface between the host con-

troller and the HT1647. The HT164X series

have many kinds of products that match vari-

ous applications.
