General Description

The HT16C22/HT16C22G device is a memory mapping and multi-function LCD controller driver. The maximum

Display segments of the device are 176 patterns (44 segments and 4commons). The software conﬁguration feature

of the HT16C22/HT16C22G makes it suitable for multiple LCD applications including LCD modules and display

subsystems. The HT16C22/HT16C22G device communicates with most microprocessors / microcontrollers via a

two-line bidirectional I²C-bus.
