General Description
The HT16C24/HT16C24G device is a memory
mapping and multi-function LCD controller driver.
The Display segments of the device may be 288
patterns (72 segments and 4 commons), 544 patterns
(68 segments and 8 commons) or 960 patterns
(60 segments and 16 commons). The software
configuration feature of the HT16C24/HT16C24G
device makes it suitable for multiple LCD applications
including LCD modules and display subsystems. The
HT16C24/HT16C24G device communicates with
most microprocessors / microcontrollers via a two-
line bidirectional I²C-bus.
