HT1635C/HT1635D

44×8 LED Driver

Features

General Description

• Operating voltage: 2.4V~5.5V

• LED display -- 44 row and 8 Columns

• 88×4 bit RAM display data storage

• 16-level PWM brightness control

• Integrated 256kHz RC oscillator

• I²C-bus or 4-wire serial interface

• Data mode & command mode instructions

• Cascade function for extend applications

The HT1635C/HT1635D series is a memory mapping

LED display controller/driver. The maximum display

capacity of the device is 352 patterns composed of

44 rows and 8 commons. The devices can generate

16 LED illumination levels using software controlled

PWM circuitry. A serial interface is provided to allow

the device to receive instructions for its command

mode and data mode. Only two or four lines are

required to interface the device to a host controller.

The display capacity can be easily extended by

cascading the devices thus expanding its application

possibilities. The device is compatible with most

microcontrollers oﬀering easy interfacing via its two

serial interfaces, an I²C bus or a 4-wire serial bus.

• Selectable NMOS open drain output driver and

PMOS open drain output driver for COM lines

• 64-pin LQFP package

Applications

• Industrial control displays

• Digital clocks, thermometers, counters, electronic

meters

• Instrumentation readouts

• Other consumer applications

• LED displays
