HT16K33A

RAM Mapping 16×8 LED

Controller Driver with Keyscan

• VCR sets

Feature

• Instrumentation readouts

• Other consumer applications

• LED Displays

• Operating voltage: 4.5V~5.5V

• Integrated RC oscillator

• I²C bus interface

• 16×8 bits RAM for display data storage

• Max. 16×8 patterns, 16 segments and 8 commons

• R/W address auto increment

General Description

The HT16K33A is a memory mapping and multi-function

LED controller driver. The maximum display segment

numbers in the device is 128 patterns (16 segments and 8

commons) with a 13×3 (MAX.) matrix key scan circuit.

The software conﬁguration features of the HT16K33A

makes it suitable for multiple LED applications

including LED modules and display subsystems. The

HT16K33A is compatible with most microcontrollers

and communicates via a two-line bidirectional I²C

bus.

• Max. 13×3 matrix key scanning

• 16-step dimming circuit

• Package types: 20/24/28-pin SOP/SSOP

Applications

• Industrial control indicators

• Digital clocks, thermometers, counters, multimeters

• Combo sets
