IS31FL3199
9-CHANNEL LIGHT EFFECT LED DRIVER
October 2018
GENERAL DESCRIPTION
FEATURES
IS31FL3199 is a 9-channel light effect LED driver
which features two-dimensional auto breathing mode
and an audio modulated display mode. It has One Shot
Programming mode and PWM Control mode for RGB
lighting effects. The maximum output current can be
adjusted in 8 levels (5mA~40mA).
In PWM Control mode, the PWM duty cycle of each
output can be independently programmed and
controlled in 256 steps to simplify color mixing. In One
Shot Programming mode, the timing characteristics for
output current - current rising, holding, falling and off
time, can be adjusted individually so that each output
can independently maintain a pre-established pattern
achieving mixing color breathing or a single color
breathing without requiring any additional interface
activity, thus saving valuable system resources.
The IS31FL3199 includes an audio modulated display
mode, wherein the brightness of LED can be
modulated by audio signal. There is a cascade pin for
the synchronization of two chips.

IS31FL3199
DETAILED DESCRIPTION
The 8-bit chip address is sent next, most significant bit
first. Each address bit must be stable while the SCL
level is high.
I2C INTERFACE
The IS31FL3199 uses a serial bus, which conforms to
the I2C protocol, to control the chip’s functions with two
wires: SCL and SDA. The IS31FL3199 has a 7-bit slave
address (A7:A1), followed by the R/W bit, A0. Since
IS31FL3199 only supports write operations, A0 must
always be “0”. The value of bits A1 and A2 are decided
by the connection of the AD pin.
After the last bit of the chip address is sent, the master
checks for the IS31FL3199’s acknowledge. The
master releases the SDA line high (through a pull-up
resistor). Then the master sends an SCL pulse. If the
IS31FL3199 has received the address correctly, then it
holds the SDA line low during the SCL pulse. If the SDA
line is not low, then the master should send a “STOP”
signal (discussed later) and abort the transfer.
The complete slave address is:
Table 1 Slave Address (Write Only):
Bit
A7:A3
A2:A1
A0
Value
11001
AD
0
Following acknowledge of IS31FL3199, the register
address byte is sent, most significant bit first.
IS31FL3199 must generate another acknowledge
indicating that the register address has been received.
AD connected to GND, AD = 00;
AD connected to VCC, AD = 11;
AD connected to SCL, AD = 01;
AD connected to SDA, AD = 10;
Then 8-bit of data byte are sent next, most significant
bit first. Each data bit should be valid while the SCL
level is stable high. After the data byte is sent, the
IS31FL3199 must generate another acknowledge to
indicate that the data was received.
The SCL line is uni-directional. The SDA line is
bi-directional (open-collector) with a pull-up resistor
(typically 4.7kΩ). The maximum clock frequency
specified by the I2C standard is 400kHz. In this
discussion, the master is the microcontroller and the
slave is the IS31FL3199.
The “STOP” signal ends the transfer. To signal “STOP”,
the SDA signal goes high while the SCL signal is high.
ADDRESS AUTO INCREMENT
To write multiple bytes of data into IS31FL3199, load
the address of the data register that the first data byte
is intended for. During the IS31FL3199 acknowledge of
receiving the data byte, the internal address pointer will
increment by one. The next data byte sent to
IS31FL3199 will be placed in the new address, and so
on (Figure 6).
The timing diagram for the I2C is shown in Figure 3.
The SDA is latched in on the stable high level of the
SCL. When there is no interface activity, the SDA line
should be held high.
The “START” signal is generated by lowering the SDA
signal while the SCL signal is high. The start signal will
alert all devices attached to the I2C bus to check the
incoming address against their own chip address.

IS31FL3199
TYPICAL APPLICATION
GENERAL DESCRIPTION
IS31FL3199 is a 9-channel LED driver with
two-dimensional auto breathing and PWM Control
mode. It can drive nine LEDs or three groups RGB.
POWER ON SEQUENCE
IS31FL3199 provides a power-on reset feature that is
controlled by VBAT (voltage at pin1) supply voltage.
When the VBAT exceeds 2.0V (POR_H, Typ.), the
internal circuit starts to work. The reset signal will be
generated to perform a power-on reset (POR_H)
operation, which will reset all control circuits and
configuration registers until the internal power voltage
become stable.
Before SDB pull high, the I2C operation is allowed. The
SDB rising edge will reset the I2C bus.
RGB BREATHING CONTROL WITH AUTO COLOR
CHANGING
By setting the RGBx bits of the Configuration
Register1 (03h) to “1”, the IS31FL3199 will operate in
One Shot Programming mode. In this mode each
group RGB can be modulated breathing cycle
independently by T0~T4. The full cycle is T1 to T4
(Figure 8). Setting different T0~T4 can achieve RGB
breathing with auto color changing. The maximum
intensity of each RGB can be adjusted independently
by the PWM Registers (07h~0Fh).
Note, if IS31FL3199 operates in the One Shot
Programming mode and then enters into the shutdown
mode, an 8-bit data write operation to the Time Update
Register is required to restart the LED breathing effect
after the IC is re-enabled.
Figure 8
Breathing Timing
RGB AUTO BREATHING CONTROL WITH COLOR
SETTING
Figure 7 SDB Pin Sequence
Note 1: I2C operation is allowed when SDB is low.
Note 2: There should be no I2C operation 10µs before and after SDB
rinsing edge.
In some case, like a mouse, when plug-out and quickly
plug-in back the USB power, the LED will flash for a
very short time. The reason is the power is not lower
than the POR_L voltage point 1.92V (Typ.), and the
device still stores the previous setting data, if user
pull-up the SDB high when power up, following with the
initial operation, the LED will be ON between SDB rising
edge and PWM initial effective, to avoid this, as above
figure, a writing to 00h is recommended to shutdown
the chip before pull-high the SDB pin.
PWM CONTROL
By setting the RGBx bits of the Configuration Register1
(03h) to “0”, the IS31FL3199 will operate in PWM
Control mode. The PWM Registers (07h~0Fh) can
modulate LED brightness of 9 channels with 256 steps.
For example, if the data in PWM Register is “0000
0100”, then the PWM is the fourth step.
Writing new data continuously to the registers can
modulate the brightness of the LEDs to achieve a
breathing effect.
Lumissil Microsystems – www.lumissil.com
Rev. C, 10/15/2018
IS31FL3199 can pre-establish pattern achieving
mixing color breathing. There are three groups RGB.
Each RGB consists of three channels. Every channel
has an 8-bit PWM data register. The color can be set
by the PWM data register. For example, there are three
PWM data: 20h, 80h, C8h, so the three data will
determine a kind of color.
After setting the color, T0~T4 time register will be set to
control the LED breathing panel. And T0~T4 time
should be same for one RGB or the pre-established
color will change.
SEMIAUTOMATIC BREATHING
By setting the RGBx bits of the Configuration
Register1 (03h) to “1” and the RM bit of the Ramping
Mode Register (05h) to “1”, the ramping function is
enabled. HT is the time select bit. When HT bit is set to
“0”, T2 will be held forever, and the LED will remain at
the programmed maximum intensity. When HT bit is
set to “1”, T3 will continue and T4 will be held, causing
the LED to complete one breathing cycle and then
remain off.
AUDIO MODULATE DISPLAY MODE WITH AGC
FUNCTION
In audio modulate display mode the output current can
be modulated by the audio input signal. An AGC
automatically adjusts the audio input gain to improve
the dynamic range of the LED current modulation, thus
improving the visual effect. When the input signal is

large such that the amplifier output begins to clip, the
gain goes down. If the input signal is small, the gain
increases, adjusting the output to provide a good
dynamic response to the input signal.
master. There are two pins (CLK, I_AUD) for
synchronization of chips. CLK pin can synchronize the
breathing and I_AUD pin can synchronize the audio
current.
The AGC can be disabled and the audio gain can be
set by programming Configuration Register 1 (03h).
SHUTDOWN MODE
BREATHING MARK FUNCTION
By setting the BME bit of the Breathing Mark Register
(06h) to “1”, the breathing mark function is enabled.
The CLK/V_BM pin is used as V_BM. If the BME bit
sets to “0”, the breathing mark function disabled. The
CLK/V_BM pin is used as CLK. V_BM is an output pin.
The breathing mark function is useful as a signal to
notify the MCU when to update the color data. At the
end of time period T1, V_BM will induce a falling edge
and hold logic low, so the new data can be sent by MCU
at this time. At the end of T3, V_BM will induce a rising
edge and the MCU can send an update command to
update all data simultaneously (Figure 9). The marking
channel (OUT1~OUT9) is selected by the CSS bits of
the Breathing Mark Register (06h).
When IS31FL3199 operates as slave, the breathing
mark function is unavailable.
Shutdown mode can either be used as a means of
reducing power consumption or generating a flashing
display (repeatedly entering and leaving shutdown
mode). During shutdown mode all registers retain their
data and can be accessed via the I2C bus interface.
The only difference between Software and Hardware
shutdown mode is the current consumption.
Software Shutdown
By setting SSD bit of the Shutdown Register (00h) to
“0”, the IS31FL3199 will operate in software shutdown
mode, wherein it consumes only 2μA (Typ.) current.
When the IS31FL3199 is in software shutdown mode,
all current sources are switched off.
Hardware Shutdown
The chip enters hardware shutdown mode when the
SDB pin is pulled low, wherein it consumes only 1μA
(Typ.) current. When the IS31FL3199 is in hardware
shutdown mode, all current sources are switched off.

CASCADE FOR SYNCHRONIZATION OF CHIPS
All registers are accessible (read or write) while the
IS31FL3199 is in either Software or Hardware
shutdown. SDB turn on time is about 200µs, do not
send I2C commands during a rising edge of the SDB
pin as data will be corrupted. Data transfers during
SDB falling edge, low or high steady state are
permitted.
Operating in the cascade mode can make two chips
synchronize. By setting the CM bit of Configuration
Register 2 (04h) to “0”, IS31FL3199 operates as a
