General Description

The HT16C23/HT16C23G device is a memory

mapping and multi-function LCD controller driver.

The Display segments of the device are 224 patterns

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

segments and 8commons). The software conﬁguration

feature of the HT16C23/HT16C23G device makes it

suitable for multiple LCD applications including LCD

modules and display subsystems. The HT16C23/

HT16C23G device communicates with most

microprocessors / microcontrollers via a two-line

bidirectional I²C-bus.

– 52 x 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 V_LCDpin to adjust LCD operating voltage

Manufactured in silicon gate CMOS process

Package Type: 48LQFP, 64LQFP, Chip and

Goldbump chip.
