NJU6063
RGB LED Controller Driver with PWM Control
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
The NJU6063 is RGB LED controller driver with PWM control.
It contains PWM controller, LED drivers, I2C interface and constant current
driver etc. and can control RGB LED individually.
NJU6063 can reduce board density because the external parts are
unnecessary for it includes constant current driver.
Making LED a polychromatic light is possible by the control of the PWM
dimming Circuit.
Also, multiple NJU6063 can be controlled by the multi device control.
The NJU6063 is suited for a large number of applications such as cellular
phones, car stereo sets, household appliances, illumination equipment and
gaming equipments, etc.

Data Output terminal 1
The following two kinds of use can be selected by the instruction.
1) Multi device control
Please connect it with terminal RSTb of NJU6063 in the next device.
2) Enable control of external LED driver
It can be use as enable control output terminal using an external LED driver. It outputs “H” level
or “L” level by instruction code.
Data Output terminal 2
It outputs the PWM signal same as LED3 Terminal.
It is used to PWM dimming using an external LED driver.
LED Output terminal (Open drain output)
Output level can be divided into 128 steps by PWM signal. Connecting with the cathode of LED.
Connecting with the cathode of LED.
N.C.
Not connect. These terminals are electrically open.

NJU6063
(1) Description for Each Block
(1-1) PWM Luminance Control Circuit
The NJU6063 incorporates three 128 steps PWM Luminance Control circuits.
At the user’s option, PWM data can be set.
The frame frequency can be changed by the instruction.

(1-2) Oscillator Circuit
The oscillation circuit with the internal register and capacitor generates the clock signal for PWM.
The oscillation circuit can be turned on/off by the instruction to minimize the current consumption.
• The PWM frequency can be selected by the instruction.
• Additionally, it can operate the external clock without using the internal oscillation circuit.
(Note) NJU6063 becomes lights-out state immediately with turning off internal oscillator during LED lights-on.
The lighting status will return just moments before status when the internal oscillator restarted.
Therefore, the LED luminance may be changed a moment when the internal oscillator was turned on.
To avoid this, you should set PWM to "00h" so that lights-off LED, and then turn off the internal
oscillator.

(1-3) LED Luminance Control Setting
There are the following three methods of LED Luminance setting.
(a) Setting of maximum LED current with ISET Terminal (LED1∼3 common setting)
(b) LED Current Magnification Setting (LED1∼3 Separate setting)
(c) PWM Signal Setting (LED 1∼3 Separate setting)
(a) Setting of maximum LED current with ISET Terminal (LED1∼3 common setting)
The setting of maximum LED current connects resistance between the terminal ISET and the terminal AVSS.
The Maximum LED current range can be set in the 5mA to 10mA range.
I LED =
200[times] × 0.5[V ] 100
=
RISET
RISET
(Ex. ILED(MAX)=30.3mA setting, RISET=3.3kΩ)
The LED drive transistor is turned off and the LED driving current is intercepted when ISET Terminal
and AVSS Terminal are short-circuited.
(b) LED Current Magnification Setting (LED1∼3 Separate setting)
The LED current of each LED Terminal can be set the following three magnification: one time, one harf
and one-quarter against ILED(MAX) that set by RISET.
The I2C instruction can set this setting.
Refer to (3) Instruction code: (3-2) LED current setting in detail.
(c) PWM Signal Setting (LED 1∼3 Separate setting)
The PWM signal of each LED terminal is set according to the instruction.
PWM Duty can divide between 0% to 100% into 128.
Refer to (3) Instruction code: (3-3) PWM setting in details.
(1-4) Multi Device Function
NJU6063 can control multi device (a number of NJU6063) on I2C bus line.
Refer to (7) Multi Device Control in details.
(1-5) PWM Data Output Function
The PWM data is output as CMOS output that set to LED3 from DO2 Terminal.
The PWM data is waveform inverted of LED3 Terminal output and this output control is same as LED3
setting.
Moreover, the large current drive LED port can be added by connecting the DO2 Terminal to NJU6080
PWM terminal.

NJU6063
(2) Instructions
The NJU6063 can set the PWM data by I2C interface. The NJU6063 has auto increment function.
So the Lower Address causes the next loop iteration by auto increment.
Apstream: from 00h to 07h, Subsequently: from 02h to 07h
Therefore, it can be write the instruction code from the LED1 PWM setting to START/STOP setting continuously until
becoming I2C stop condition.
Moreover, the lower address that the instruction: 08h to 0Fh is been auto increment to the lower address 02h after
running.

Regarding Gradual Dimming Operating Time
The Gradual Dimming Operating Time depends on each following setting: Frame Frequency, Step
Number and Loop Frequency. The formula is as follows.
Operating Time = Frame Frequency×[(Step Number+1)×Loop Number+1(Internal Processing Time)]
i.e. In case of Frame Frequency: 3.9kHz, Step Number: 32, Loop Number: 64
Operating Time =
1
× [(32 + 1) × 64 + 1] = 0.542[sec]
3.9[kHz]
In actual operation, this function to start running in synchronization with the frame signal.
Therefore, the frame may be delayed maximum one (1) frame cycle against the calculated time.
Running Instruction under Gradual Dimming Operating
During Gradual Dimming operation, IC inside is BUSY state.
Therefore, does not accept non-specific instruction.
In addition, ACK is not output about not acceptable instructions.
If ACK is not output, it should resend from START condition.

Normal Function
The Gradual Dimming operation does the forced stop by making it to D1=1 by the START/STOP
instruction. The PWM output of each LED terminal after forced stop becomes the PWM output of
point that does the forced stop.
Moreover, Gradual Dimming operates to the PWM data set from the last PWM data setting value
again in the Dimming setting immediately after compulsion the stop.
When the forced stop is done, it is not possible to restart. You should set a data again.

Gradual Dimming Start Function
START : Gradual Dimming Function Start
The Gradual Dimming function starts with D0=1. The actual execution start synchronizes to
the frame signal. The PWM output of each LED Terminal is not updated with D0=0.
Moreover, during running the Gradual Dimming function, D0 = 0 is not accepted.
Therefore, running the Gradual Dimming function does not stop.
Force Stop Function
STOP : Force Stop under Gradual Dimming Function
The Gradual Dimming function stops with D0=0. The stop procedure synchronizes to the
frame signal. The PWM output of each LED Terminal is not updated with D0=0.
It should set the STOP setting "H” to D1 after specifying the Lower address 07h.
(It doesn't accept except 07h and 0Fh instruction while executing the function.)
Refer to (3-4) Gradual Dimming Setting regarding behavior at Force Stop.
Caution: DO NOT SET STOP and START to “H” at the same time.

When SCL Terminal is High level, the data read-in is started by falling edge inputting to SDA Terminal.
2. Slave address
You should input the Slave Address and R/W condition to 1st byte data. The NJU6063 Slave Address is
(0100_000). When the Slave Address is corresponding to written Data, ACK is output to 9th bit.
It does not correspond to general code address.
3. Register Upper Address
It should input Register Upper Address to 2nd byte data. Even if the Upper Address is not corresponding, ACK
is output to the ninth bit if the Slave Address is corresponding.
4. Register Lower Address
It should input Register Lower Address to 3rd byte data. When the Slave Address is corresponding to written
Data, ACK is output to 9th bit. When the Slave Address is not corresponding to written Data, ACK is not output to
9th bit.
5. Data
It should input a Data to 4th byte data or later.
Only when it doesn't complete internal processing by gradual dimming within IC, ACK is not output against input
data (Processing Condition Internal IC-2).
If ACK is not output, it should re-enter data from the (1) Start Condition.
Refer to (3-4) Gradual Dimming Setting regarding detailed Gradual Dimming Operating Time.
6. Stop condition
When SCL Terminal is High level, the data read-in is stopped by rising edge inputting to SDA Terminal.
7. Repeat start condition
When SCL Terminal is High level after Start Condition setting, the data read-in is started by falling edge inputting
to SDA Terminal.
(Note): When VDD=1.8V, you should use I2C standard mode.

(8) Control of NJU6080
NJU6080 can be controlled by using the terminal DO1 and the terminal DO2 of NJU6063.
(Refer to APPRICATION CIRCUIT Example 2)
The LED current can be increased by connecting NJU6080 more than NJU6063. The PWM data of LED3
becomes the PWM data of NJU6080.
