HT1632D/HT1632D-2

32×8 & 24×16 LED Driver

Features

Applications

• Operating voltage: 2.4V~5.5V

• Industrial control indicator

• Digital clock, thermometer, counter, voltmeter

• Instrumentation readouts

• Multiple LED display − 32 ROW & 8 COM and

24 ROW & 16 COM

• Integrated display RAM − select 32 ROW &

8 COM for 64×4 display RAM, or select

24 ROW & 16 COM for 96×4 display RAM

• Other consumer application

• LED Displays

• 16-level PWM brightness control

General Description

• Integrated 256kHz RC oscillator

• Serial MCU interface − CS, RD, WR, DATA

• Data mode & command mode instruction

• Cascading function for extended applications

The devices are a memory mapping LED display

controller/driver, which can select a number of ROW

and commons. These are 32 ROW & 8 Commons

and 24 ROW & 16 Commons. The devices support

16-gradation LEDs for each out line using PWM

control with software instructions. A serial interface

is conveniently provided for the command mode

and data mode. Only three or four lines are required

for the interface between the host controller and the

devices. The display can be extended by cascading the

devices for wider applications.

• Selectable NMOS open drain output driver and

PMOS open drain output driver for commons

• 48/52-pin LQFP package
