General Description
HT1647 is a peripheral device specially de-
signed for I/O type
C 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.
