General Description

♦

Max. 20×1 matrix key scanning in

The HT16K23A is a memory mapping and multi-

function LCD controller driver. The Max. display

segment numbers in the device are 80 patterns (20

segments and 4 commons) or 128 patterns (16 segments

and 8 commons). The Max. key scan circuits are 20×1

matrix or 16×1 matrix. The software configuration

feature of the HT16K23A makes it suitable for multiple

LCD applications including LCD modules and display

subsystems. The HT16K23A supports a hardware

interrupt using register setting.

20×4 display mode

♦

Max. 16×1 matrix key scanning in

16×8 display mode

• 16×8 bits RAM for display data storage

• Selectable hardware interrupt

• R/W address auto increment

• Manufactured in silicon gate COMS process

• 28-pin SOP/SSOP package

The HT16K23A is compatible with most microcontrollers

and communicates via a two-line bidirectional I²C-bus.
