General Description
HT1660 is a peripheral device specially designed for I/O
type
max. display segment of the device are 3072 patterns
(96 segments and 32 commons). It also supports four
data bits interface, buzzer sound, Watchdog Timer or
time base timer functions. The HT1660 is a memory
mapping and multi-function LCD controller. Since the
used to expand the display capability. The
MCU
·

·
Consumer electronics
HT1660 can control TN-type (Twisted Nematic) or
STN-type (Super Twisted Nematic) LCDs. The software
configuration feature of the HT1660 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 HT1660.
