Rev. C, 03/22/2017
DESCRIPTION
The IS32FL3738 is an automotive grade general
purpose 6×8 LEDs matrix driver with 1/12 cycle rate.
The device can be programmed via an I2C compatible
interface. Each LED can be dimmed individually with
8-bit × 4 PWM data which allowing 512 steps of linear
dimming.
IS32FL3738 features 3 Auto Breathing Modes which
are noted as ABM-1, ABM-2 and ABM-3. For each Auto
Breathing Mode, there are 4 timing characters which
include current rising / holding / falling / off time and 3
loop characters which include Loop-Beginning /
Loop-Ending / Loop-Times. Every LED can be
configured to be any Auto Breathing Mode or
No-Breathing Mode individually.
FEATURES
Up to 48 LEDs (6×8) in dot matrix
Programmable 6×8 (16 RGBs) matrix size with
de-ghost function
Selectable 3 Auto Breath Modes for each dot
Auto Breath Loop Features interrupt pin inform
MCU Auto Breath Loop completed
Auto Breath offers 128 steps gamma current,
interrupt and state look up registers
256 steps Global Current Setting
Individual 512 PWM control steps
Individual Auto Breath Mode select
Individual open and short error detect function

(V01A board with 12V DC input please refer to Appendix
Ⅰ
)
RECOMMENDED EQUIPMENT
5.0V, 2A Micro USB
Arduino IDE, www.arduino.cc/en/Main/Software
Arduino code download from ISSI website
ABSOLUTE MAXIMUM RATINGS
≤5.5V Micro USB DC power supply
Caution: Do not exceed the conditions listed above, otherwise
the board will be damaged.
PROCEDURE
The IS32FL3738 evaluation board is fully assembled,
tested and comes programmed with evaluation
software. Follow the steps listed below to verify board
operation.
Caution: Do not turn on the power supply until all connections
are completed.
1) Connect the 5VDC USB power to the Micro USB.
2) Press K1 to cycle through a display mode.
EVALUATION BOARD OPERATION
The IS32FL3738 evaluation board drives16 RGB
LEDs located underneath the light dispersing filter.
Every press of the K1 switch will cycle through one of
the 8 pre-programmed lighting sequences below:
1) White LED
2) Rainbow bar
3) Red color breath
4) Green color breath
5) Blue color breath
6) Pink color breath
7) Yellow color breath
8) Cyan color breath
Note: IS32FL3738 solely controls the FxLED function on the
evaluation board.

SOFTWARE CONTROL
The evaluation board comes with an Arduino
compatible microcontroller circuit preloaded with
IS32FL3738 demonstration firmware, called a sketch.
This allows the functionality of the IS32FL3738 to be
verified before starting firmware development.
The Arduino hardware consists of an Atmel
microcontroller with a bootloader allowing quick
firmware updates. First download the latest Arduino
Integrated Development Environment IDE (1.6.12 or
greater) from www.arduino.cc/en/Main/Software.
Then download the latest IS32FL3738 firmware
(sketch) from the ISSI website
www.issi.com/US/product-analog-automotive.shtml.
When using the Arduino environment, please select
Genuino UNO as shown below, then select the serial
port. Follow the standard procedure to upload the
latest IS32FL3738 firmware into the Arduino; then
use the IDE to modify it. There is no additional
software required to run the eval board.
EXT-SOFTWARE CONTROL
The IS32FL3738 can also be driven by an external IIC
source.
Follow the steps below to configure the eval board for
external control.
1) Open the two pins of J7 on the right side, to
disable the onboard Arduino and enable external
control (the SDA SCL and SDB become high
impedance).
2) Default VIO is 5V, if you use a 3.3V IO, connect
3.3V to VIO pin in J7.
3) Connect SDB to VIO or high level IO
4) Connect external IIC to the IIC pins of J7
5) Start external IIC control.

Caution: Do not exceed the conditions listed above, otherwise
the board will be damaged.
PROCEDURE V01A
The IS32FL3738 evaluation board is fully assembled
and tested. Follow the steps listed below to verify
board operation.
Caution: Do not turn on the power supply until all connections
are completed.
1) Connect the 12VDC power to the connector or
5VDC USB power to the Micro USB.
2) Turn on the power supply, pay attention to the
supply current. If the current exceeds 1A, please
check for circuit fault.
EVALUATION BOARD OPERATION V01A
The IS32FL3738 evaluation board has three
animation display modes. Press K1 to switch
configurations.
1) White LED
2) Rainbow bar
3) Red LED breath
4) Green LED breath
5) Blue LED breath
6) Red and blue LED breath
7) Red and green LED breath
8) Blue and green LED breath
Note: IS32FL3738 solely controls the FxLED function on the
evaluation board.
SOFTWARE CONTROL
The IS32FL3738 use Arduino as is master controller,
if using Arduino environment, please select Genuino
UNO. No driver is need when initial the hardware.
EXT-SOFTWARE CONTROL V01A
The IS32FL3738 can set its I2C bus interface logic
threshold based on the voltage on the VIO pin.
Follow the steps listed below for external control.
1) Open JP1 to disconnect the I2C communication,
and connect an external MCU VCC to VIO.
2) Pull-up the SDB to VIO.
3) Connect the 12VDC power to the connector or
5VDC power to the Micro USB.
4) Turn on the power supply pay attention to the
supply current. If the current exceeds 1A, please
check for circuit fault.
5) Start external IIC control.
