General Description

♦

56×4 patterns: 56 segments and 4 commons

The HT16C23A/HT16C23AG devices are a memory

mapping and multi-function LCD controller driver.

The display segments of the devices are 224 patterns

(56 segments and 4 commons) or 416 patterns (52

segments and 8 commons). The software conﬁguration

feature of the devices make it suitable for multiple

LCD applications including LCD modules and display

subsystems. The devices communicate with most

microprocessors/microcontrollers via a two-line

bidirectional I²C bus.

♦

52×8 patterns: 52 segments and 8 commons

• Versatile blinking modes

• 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: 48/64-pin LQFP and COG
