General Description

– 16 x 8 patterns: 16 segments and 8 commons

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.

Versatile blinking modes

●

R/W address auto increment

Internal 16-step voltage adjustment to adjust LCD

operating voltage

Low power consumption

●

Provides V_LCDpin to adjust LCD operating voltage

Manufactured in silicon gate CMOS process

Package Type: 20/24/28 SOP, 16 NSOP and Chip.
