General Description
The HT9B92 device is a memory mapping and
multi-function LCD controller driver. The maximum
display segments of the device are 144 patterns (36
segments and 4 commons) display. The software
configuration feature of the HT9B92 device makes
it suitable for multiple LCD applications including
LCD modules and display subsystems. The HT9B92
device communicates with most microprocessors/
microcontrollers via a two-wire bidirectional I²C-bus
interface.
