General Description

The HT16C22A/HT16C22AG devices are a memory

mapping and multi-function LCD controller driver.

The maximum display segments of the devices are 176

patterns (44 segments and 4 commons). The software

conﬁguration feature of the HT16C22A/HT16C22AG

devices make it suitable for multiple LCD applications

including LCD modules and display subsystems. The

HT16C22A/HT16C22AG devices communicate with

most microprocessors/microcontrollers via a two-line

bidirectional I²C bus.

• R/W address auto increment

• Internal 16-step voltage adjustment to adjust LCD

operating voltage

• Low power consumption

• Provides the VLCD pin to adjust LCD operating

voltage

• Manufactured in silicon gate CMOS process

• Package Types: 48/52-pin LQFP and COG
