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. It is a memory mapping and multi-function LCD controller. Since it 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 it.
