General Description

Integrated LED driver

Support I²C or SPI 3-wire serial interface

controlled by IFS pin

●

The HT16L23 device is a memory mapping and

multi-function LCD controller/driver. The display

segments of the device are 208 patterns (52 segments

and 4 commons) for 1/4 duty display or 384 patterns

(48 segments and 8 commons) for 1/8 duty display.

It can also support LED drive outputs on certain

segment pins. The software configuration feature of

the HT16L23 device makes it suitable for multiple

LCD applications including LCD modules and display

subsystems. The HT16L23 device communicates with

most microprocessors/microcontrollers via a two-wire

bidirectional I²C or a three-wire SPI interface.

Four selectable LCD frame frequencies: 64Hz or

85.3Hz or 128Hz or 170.6Hz

●

Up to 48×8 bits RAM for display data storage

●

Display pixel:

– 52×4 pixel: 52 segments and 4 commons

– 48×8 pixel: 48 segments and 8 commons

Support two driver output mode segment/LED on

SEG44~SEG51/LED7~LED0

●

Versatile blinking modes: off, 0.5Hz, 1Hz, 2Hz

R/W address auto increment

●

Low power consumption

Manufactured in silicon gate CMOS process

Package type: 64LQFP package
