General Description
The device is a memory mapping and multi-function
LCD controller driver. The maximum display
segments of the device are 160 patterns (40 segments
and 4commons) display. The software configuration
feature of the HT9B92G device makes it suitable for
multiple LCD applications including LCD modules
and display subsystems. The device communicates
with most microprocessors / microcontrollers via a
two-wire bidirectional I²C-bus interface.
