General Description

The HT16C21 device is a memory mapping and

multi-function LCD controller/driver. The display

segments of the device are 80 patterns (20 segments

and 4 commons) or 128 patterns (16 segments and 8

commons). The software configuration feature of the

HT16C21 device makes it suitable for multiple LCD

applications including LCD modules and display

subsystems. The HT16C21 device communicates with

most microprocessors/microcontrollers via a two-line

bidirectional I2C interface.
