General Description
HT1647A 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 HT1647A is a memory
mapping and multi-function LCD controller. Since the
HT1647A can control ECB-type (Electrically Controlled
Birefringence) LCDs in addition to current TN-type
(Twisted Nematic) or STN-type (Super Twisted Ne-
matic) LCDs. The software configuration feature of the
HT1647A make it suitable for multiple LCD applications
including LCD modules and display subsystems. Only
six lines (CS, WR, DB0~DB3) are required for the inter-
face between the host controller and the HT1647A.
