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
