HT1647 -- 4-Level Gray Scale 64x16 LCD Controller For I/O MCU

HT1647 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 1024 patterns (64 segments and 16 commons). It also supports four data bits Interface 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 (Electrically Controlled Birefringence) LCDs in addition 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 the HT1647 drives a TN-type, STN-type LCDs It Displays four color output when the HT1647 drives an 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 subsystems. Only six lines (CS, WR, DB0~DB3) are required for the Interface between the host controller and the HT1647.
