Digital Red, Green and Blue Color Light Sensor with IR Blocking Filter
Features
The ISL29125 is a low power, high sensitivity, RED, GREEN and
BLUE color light sensor (RGB) with an I2C (SMBus compatible)
interface. Its state-of-the-art photodiode array provides an
accurate RGB spectral response and excellent light source to
light source variation (LS2LS). The ISL29125 is designed to
reject IR in light sources allowing the device to operate in
environments from sunlight to dark rooms. The integrating
ADC rejects 50Hz and 60Hz flicker caused by artificial light
sources. A selectable range allows the user to optimize
sensitivity suitable for the specific application. In normal
operation mode the device consumes 56µA, which reduces to
0.5µA in power-down mode. The ISL29125 supports hardware
and software user programmable interrupt thresholds. The
Interrupt persistency feature reduces false trigger notification.
The device operates on supplies (VDD) from 2.25V to 3.63V, I2C
supply from 1.7V to 3.63V, and operating temperature across the
-40°C to +85°C range.

ISL29125
Principles of Operation
Photodiodes and ADC
The ISL29125 contains three photodiode arrays, which convert
light into current. The spectral response for RED, GREEN and
BLUE color ambient intensity sensing is shown in Figure 2. After
light is converted to current during the light to signal process, the
current output is converted to a digital count by an on-chip
Analog-to-Digital Converter (ADC). The ADC converter resolution
is selectable from 12 or 16 bits. The ADC conversion time is
inversely proportional to the ADC resolution.
The ADC converter uses an integrating architecture. This
conversion method is ideal for converting small signals in the
presence of a periodic noise. A 100ms integration time (16-bit
mode) for instance, rejects 50Hz and 60Hz power line as well as
florescent flicker noise.
The ADC integration time is determined by an internal oscillator
and the n-bit (n = 12, 16) counter inside the ADC. A good
balancing act of integration time and resolution depends on the
application for optimum system performance.
The ADC provides two programmable ranges to dynamically
accommodate different lighting conditions. For dim conditions,
the ADC can be configured at its high sensitivity (low optical)
range. For bright conditions, the ADC can be configured at its low
sensitivity (higher optical) range. Note that the effective optical
sensitivity of the ISL29125 in terms of counts/µW/cm2 is
directly proportional to the ADC integration time.
SYNC Mode
SYNC mode is when B5 at Reg0x1 is set to ‘1’, the INT pin
becomes an input pin. This mode is beneficial for some systems
which have multiple sensors on I2C bus. Once B5 is set, on the
rising edge of INT the ADC starts conversion so that multiple
devices would measure at exactly the same time. Yet, to read
data out, the system needs to have a different I2C address for
each sensor or have a multiplexer. Moreover, if B5 is set to ‘0’,
then INT pin will be asserted whenever the sensor triggers an
interrupt.
Interrupt Function
The active low interrupt pin is an open-drain pull-down
configuration. The interrupt pin serves as an alarm or monitoring
function to determine whether the ambient light level exceeds
the upper threshold or goes below the lower threshold. It should
be noted that the function of ADC conversion continues without
stopping after interrupt is asserted. If the user needs to read the
ADC count that triggers the interrupt, the reading should be done
before the data registers are refreshed by the following
conversions. The user can also configure the persistency of the
interrupt pin. This reduces the possibility of false triggers, such as
noise or sudden spikes in ambient light conditions. An
unexpected camera flash, for example, can be ignored by setting
the persistency to 8 integration cycles. ISL29125 interrupt
modes can be selected at Bit[1:0] at Reg0x03 Table 11. The user
can select Red, Green or Blue to be the interrupt target. An
interrupt event (RGBTHF) bit at Reg0x08 is governed by Registers
4 through 7. The user writes a high and low threshold value to
these registers and the ISL29125 will issue an interrupt flag if
FN8424 Rev.3.00
Jan 13, 2017
the actual count stored in Registers 0x9 and 0xA for Green or
Registers 0xB and 0xC for Red or Register 0xD and 0xE for Blue
are outside the user’s programmed window. Once ISL29125
issues the interrupt flag, the interrupt status (RGBTHF) bit at
Reg0x08 is asserted to logic HIGH and the INT pin goes low. Both
the INT pin and the interrupt status bit are automatically cleared at
the end of the 8-bit Device Register byte (0x08) transfer. By default
(RGBTHF) bit is LOW or it is within the interrupt thresholds window.
Power-On Reset
The Power-On Reset (POR) circuitry protects the internal logic
against powering up in the incorrect state. The ISL29125 will
power up into Standby mode after VDD exceeds the POR trigger
level and will power down into Reset mode when VDD drops
below the POR trigger level. This bidirectional POR feature
protects the device against ‘brown-out’ failure following a
temporary loss of power.
The POR is an important feature because it prevents the
ISL29125 from starting to operate with insufficient power supply
voltage. The ISL29125 prevents communication to its registers
and reduces the likelihood of data corruption on power-up.
Serial Interface
The ISL29125 supports the Inter-Integrated Circuit (I2C) bus data
transmission protocol. The I2C bus is a two-wire serial
bidirectional interface consisting of SCL (clock) and SDA (data).
Both the wires are connected to the device supply via pull-up
resistors. The I2C protocol defines any device that sends data
onto the bus as a transmitter and the receiving device as the
receiver. The device controlling the transfer is a master and the
device being controlled is the slave. The transmitting device pulls
down the SDA line to transmit a “0” and releases it to transmit a
“1”. The master always initiates the data transfer, only when the
bus is not busy and provides the clock for both transmit and
receive operations. The ISL29125 operates as a slave device in
all applications. The serial communication over the I2C interface
is conducted by sending the Most Significant Bit (MSB) of each
byte of data first.
Start Condition
During data transfer, the SDA line must remain stable while the
SCL line is HIGH. All I2C interface operations must begin with a
START condition, which is a HIGH to LOW transition of SDA while
SCL is HIGH (refer to Figure 9). The ISL29125 continuously
monitors the SDA and SCL lines for the START condition and does
not respond to any command until this condition is met (refer to
Figure 9). A START condition is ignored during the power-up
sequence.
Stop Condition
All I2C interface operations must be terminated by a STOP
condition, which is a LOW to HIGH transition of SDA while SCL is
HIGH (refer to Figure 9). A STOP condition at the end of a
read/write operation places the device in its standby mode. If a
stop is issued in the middle of a Data byte, or before 1 full Data
byte and ACK is sent, then the serial communication of ISL29125
resets itself without performing the read/write. The contents of
the register array are not affected.
Page 6 of 17
ISL29125
Acknowledge
Write Operation
An acknowledge (ACK) is a software convention used to indicate
a successful data transfer. The transmitting device releases the
SDA bus after transmitting 8 bits. During the ninth clock cycle,
the receiver pulls the SDA line LOW to acknowledge the reception
of the eight bits of data (refer to Figure 9). The ISL29125
responds with an ACK after recognition of a START condition
followed by a valid Identification Byte and once again, after
successful receipt of an Address Byte. The ISL29125 also
responds with an ACK after receiving a Data byte of a write
operation. The master must respond with an ACK after receiving
a Data byte of a read operation
BYTE WRITE
In a byte write operation, ISL29125 requires the Device Address
byte, Register Address byte and the Data byte. The master starts
the communication with a START condition. Upon receipt of the
Device Address byte, Register Address byte and the Data byte,
the ISL29125 responds with an acknowledge (ACK). Following
the ISL29125 data acknowledge response, the master
terminates the transfer by generating a STOP condition. The
ISL29125 then begins an internal write cycle of the data to the
volatile memory. During the internal write cycle, the device inputs
are disabled and the SDA line is in a high impedance state, so the
device will not respond to any requests from the master (refer to
Figure 8).
Device Addressing
Following a START condition, the master must output a Device
Address byte. The 7 MSBs of the Device Address byte are known
as the device identifier. The device identifier bits of ISL29125 are
internally hard-wired as “1000100”. The LSB of the Device
Address byte is defined as read or write (R/W) bit. When this
R/W bit is a “1”, a read operation is selected and when “0”, a
write operation is selected (refer to Figure 7). The master
generates a START condition followed by Device Address byte
1000100x (x as R/W) and the ISL29125 compares it with the
internal device identifier. Upon a correct comparison, the device
outputs an acknowledge (LOW) on the SDA line (refer to Figure 9).

BURST WRITE
The ISL29125 has a burst write operation, which allows the
master to write multiple consecutive bytes from a specific
address location. It is initiated in the same manner as the byte
write operation, but instead of terminating the write cycle after
the first Data byte is transferred, the master can write to the
whole register array. After the receipt of each byte, the ISL29125
responds with an acknowledge and the address is internally
incremented by one. The address pointer remains at the last
address byte written. When the counter reaches the end of the
register address list, it “rolls over” and goes back to the first
Register Address.

Read Operation
ISL29125 has two basic read operations: Byte Read and Burst
Read.
The master terminates the read operation by not responding with
an acknowledge and then issuing a stop condition. Refer to
Figure 10.
BURST READ
BYTE READ
Byte read operations allow the master to access any register
location in the ISL29125. The Byte read operation is a two step
process. The master issues the START condition and the Device
Address byte with the R/W bit set to “0”, receives an
acknowledge, then issues the Register Address byte. After
acknowledging receipt of the register address byte, the master
immediately issues another START condition and the Device
Address byte with the R/W bit set to “1”. This is followed by an
acknowledge from the device and then by the 8-bit data word.

Burst read operation is identical to the Byte Read operation.
After the first Data byte is transmitted, the master now responds
with an acknowledge, indicating it requires additional data. The
device continues to output data for each acknowledge received.
The master terminates the read operation by not responding with
an acknowledge but issuing a STOP condition (refer to Figure 11).

This device has various RGB operating modes. These modes are
selected by setting B2:B0 bits in Table 4. The device powers up on
a disable mode. All operating modes are in continuous ADC
conversion. The following bits are used to enable the operating
mode.

GREEN/BLUE
The device is designed for operation under dark glass cover
which significantly attenuates visible light and passes the
infrared light without much attenuation. The device has an on
chip passive optical filter designed to block (reject) most of the
incident infrared. In addition, the device provides a
programmable active IR compensation which allows fine tuning
of residual infrared components from the output, which allows
optimizing the measurement variation between differing
IR-content light sources. B7 is “IR Comp Offset” and B[5:0] is “IR
Comp Adjust”, which provides means for adjusting IR
compensation. B7 = ‘0’ + B[5:0] is the effective IR compensation
from 0 to 63 codes and B7 set to ‘1’+B[5:0] the effective IR
compensation is from 106 to 169. Table 9 on page 11 shows
lightweight for each IR compensation bit and Figure 12 is a
typical system measure for both IR Comp Adjust and IR Comp
Offset. More detail about how to IR compensation, see IR
compensation in “Applications Information” on page 13.
RGB Data Sensing Range [B3]
The Full Scale RGB Range has two different selectable ranges at
bit 3. The range determines the ADC resolution (12 bits and
16 bits). Each range has a maximum allowable lux value. Higher
range values offer better resolution and wider lux value.

ADC Resolution [B4]
ADC’s resolution and the number of clock cycles per conversion is
determined by this bit in Table 6. Changing the resolution of the
ADC changes the number of clock cycles of the ADC which in turn
changes the integration time. Integration time is the period the
ADC samples the photodiode current signal for a measurement.
Recommended to set BF at register 0x02 to max out IR
compensation value. It make High range reach more than
10,000 lux.

INTERRUPT THRESHOLD ASSIGNMENT [B1:0]
INTERRUPT PERSIST CONTROL [B3:2]
The interrupt status bit (RGBTHF) bit0 at Reg0x08 is a status bit
for light intensity detection. The bit is set to logic HIGH when the
light intensity crosses the interrupt thresholds window (register
address 0x04 - 0x07) and set to logic LOW when it’s within the
interrupt thresholds window. Once the interrupt is triggered, the
INT pin goes low and the interrupt status bit goes HIGH until the
status bit is polled through the I2C read command. Both the INT
pin and the interrupt status bit are automatically cleared at the
end of the 8-bit Device Register byte (0x08) transfer. Table 11
shows selectable interrupt for the device.
To minimize interrupt events due to 'transient' conditions, an
interrupt persistency option is available. IN the event of a
transient condition, an 'X-consecutive' number of interrupt must
happen before the interrupt flag and PINT (INT) pin gets driven
low. The interrupt is active-low and remains asserted until the
status register (Addr: 0x08) is read to CLEAR the bit(s).

Interrupt Threshold (Reg 0x4, Reg0x5, Reg0x6 and Reg0x7)
The interrupt threshold level is a 16-bit number (Low Threshold-1 and Low Threshold-2). The lower interrupt threshold registers are used
to set the lower trigger point for interrupt generation. If the ALS value crosses below or is equal to the lower threshold, an interrupt is
asserted on the interrupt pin (LOW) and the interrupt status bit (HIGH). Registers Low Threshold-1 (0x04 or 0x6) and Low Threshold-2
(0x05 or 0x7) provide the low and high bytes, respectively, of the lower interrupt threshold. The interrupt threshold registers default to
0x00 upon power-up. The user can also configure the persistency for the interrupt pin. This reduces the possibility of false triggers, such
as noise or sudden spikes in ambient light conditions or an unexpected camera flash, for example, can be ignored by setting the
persistency to 8 integration cycles.

This is the status bit of the interrupt. The bit is set to logic high
when the interrupt thresholds have been triggered (out of
threshold window) and logic low when not yet triggered. Once
activated and the interrupt is triggered, the INT pin goes low and
the interrupt status bit goes high until the status bit is polled
through the I2C read command. Both the INT output and the
interrupt status bit are automatically cleared at the end of the
8-bit (00h) command register transfer
Bit2 on register address 0x08 is a status bit for brownout
condition (BOUT). The default value of this bit is HIGH, BOUT = 1,
during the initial power-up. This indicates the device may possibly
have gone through a brownout condition. Therefore, the status
bit should be reset to LOW, BOUT = 0, by an I2C write command
during the initial configuration of the device. The default register
value is 0x04 at power-on.

The ISL29125 has two 8-bit read-only registers to hold the higher and lower byte of the ADC value. The lower and higher bytes are
accessed at address, respectively. For 16-bit resolution, the data is from D0 to D15; for 12-bit resolution, the data is from D0 to D11.
The registers are refreshed after every conversion cycle. The default register value is 0x00 at power-on. Because all the register are
double buffered the data is always valid on the data registers.

OF LIGHT SOURCES
System Compensation and RGB to XYZ
Transform (Chroma Meter)
The accuracy of the RGB sensor is extremely sensitive to the
optomechanical design of the system in which it resides. The
compensation setting and calculation of RGB to XYZ transform
should be characterized within that environment with as many
standard illuminants as possible. A minimal recommended set
would include A, F2 and D65 illuminants (see Notes 11, 12, 13
and “References” on page 15 about IEC 1931, Planckian locus
and standard illuminants). The two most important
optomechnical features are FOV (Field Of View FWHM) and
optical filters as example of tinted cell phone glass through
which the sensor will detect the ambient lighting. With the
combination of the FOV and a large sample for the filter
(30x30mm) it is possible to determine the best compensation
and XYZ transform coefficients. It is also possible to project the
accuracy of the measurement system.
FN8424 Rev.3.00
Jan 13, 2017
COMPENSATION
The compensation adjustment is used to balance the various
illuminates of interest (A, F2 and D65 recommended) such that
the value measured at the same power level (measured with a
lux meter) is the closed value. Since the compensation
adjustment is piecewise linear the proper setting can be
determined by extrapolating from a pair of measurements and
calculating the closest intersection of the sources of interest.
The Configuration register (Reg 0x02[7:0]) allows coarse tuning
B7 and fine tuning (B[5:0] of the residual infrared component
from the ALS output.
Page 13 of 17
ISL29125
Noise Rejection
The recommended procedure for determining ALS IR
compensation is as follows:
• Illuminate the ISL29125 based design configuration with a no
IR F2 light source. Record the ALS measurement and the lux
level.
• Illuminate the device with A and D65 with heavy IR and the F2
light sources. Take an ALS measurement and lux level
measurement.
• It really depends on the system setup in order to adjust the
Configuration register (Reg 0x02, B7 and B[5:0]) to
compensate for the IR contribution.
• Repeat steps above until the IR light source contribution to the
ALS measurement is under 10 percent assuming no change in
lux level due to IR light source.
SYSTEM MEASUREMENT RANGE (lux)
Figure 14 is an example showing how to calculate the
compensation for varying level of infrared components such as
A, F2 and D65 (see Notes 11, 12 and 13 on page 11). With
compensation adjustment from 0% to 100%. The crossing point
is the IR compensation value which results in tighter variation
with varying levels of infrared components. This setup system is
a sensor without IR tinted glass and is illuminated with 3
different light sources. Since it is not under IR tinted glass, then
reg0x2 setups like b7 = ‘0’ and B[5:0] is at about 25%
compensation adjust (%/range) which means about 40 codes.
Layout and Board Mounting
Considerations
Suggested PCB Footprint
It is important that users check TB477 “Surface Mount Assembly
Guidelines for Optical Dual Flat Pack No Lead (ODFN) Package”
before starting ODFN product board mounting.
Board Mounting
12000
10000
For applications requiring the light measurement, the board
mounting location should be reviewed. The device uses an
Optical Dual Flat Pack No Lead (ODFN) package, which subjects
the die to mild stresses when the printed circuit (PC) board is
heated and cooled, which slightly changes the shape. Because of
these die stresses, placing the device in areas subject to slight
twisting can cause degradation of reference voltage accuracy. It
is normally best to place the device near the edge of a board, or
on the shortest side, because the axis of bending is most limited
in that location.

Electrical AC power worldwide is distributed at either 50Hz or
60Hz. Artificial light sources vary in intensity at the AC power
frequencies. The undesired interference frequencies are infused
on the electrical signals. This variation is one of the main sources
of noise for the light sensors. Integrating type ADC’s have
excellent noise-rejection characteristics for periodic noise
sources whose frequency is an integer multiple of the conversion
rate. By setting the sensor’s integration time to an integer
multiple of periodic noise signal, the performance of an ambient
light sensor can be improved greatly in the presence of noise. In
order to reject the AC noise, the integration time of the sensor
must be adjusted to match the AC noise cycle. For instance, a
60Hz AC unwanted signal’s sum from 0ms to k*16.66ms
(k = 1, 2...ki) is zero. Similarly, setting the device’s integration
time as an integer multiple of the periodic noise signal greatly
improves the light sensor output signal in the presence of noise.

The ISL29125 is relatively insensitive to layout. Similar to other
I2C devices, it is intended to provide excellent performance even
in significantly noisy environments. There are only a few
considerations that will ensure best performance.

Calculating Lux
Y-coordinate is Ev measured in lux. The data can be converted to
lux by using an equation. There are two different data sensing
ranges (375 lux and 10,000 lux) and also two different resolution
selections (16 bits and 12 bits) on this device. Equation 2 is
dependent on both these parameters.
Ev = Y = CYRxRed + CYGxGreen + CYBxBlue xRange

Layout
Route the supply and I2C traces as far as possible from all
sources of noise. Use two power-supply decoupling capacitors,
1µF and 0.1µF, placed close to the device.
Soldering
Convection heating is recommended for reflow soldering; direct
infrared heating is not recommended. The plastic ODFN package
does not require a custom reflow soldering profile and is
qualified to +260°C. A standard reflow soldering profile with a
+260°C maximum is recommended.
