DATASHEET ISL29125 FN8424 Rev.3.00 Jan 13, 2017 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 56A, which reduces to 0.5A 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 -40C to +85C range. * 56A operating current, 0.5A shutdown current * Selectable range (Via I2C) * I2C (SMBus compatible) output * ADC resolution 16 bits * Programmable interrupt windows * Two optical sensitivity ranges - Range 0 = 5.7m lux to 375 lux - Range 1 = 0.152 lux to 10,000 lux * Operating power supply 2.25 to 3.63V * I2C power supply 1.7V to 3.63V * 6 Ld ODFN (1.65x1.65x0.7mm) package Applications Related Literature * Smart phone, PDA, GPS, tablet PCs, LCD-TVs, digital picture frames, digital cameras AN1914, "Evaluation Hardware/Software User Manual for RGB Sensor" * Dynamic display color balancing AN1910, "Enhancing RGB Sensitivity and Conversion Time" * Printer color enhancement * Industrial/commercial LED lighting color management * Ambient light color detection/correction * OLED display aging compensation C1 Vbus R1 C2 VDD 2.0 R 2 R3 R4 VDD SDA 4 6 MCU SCL GPIO 5 R1 - 100 R2 - 2.7k to 10k R3 - 2.7k to 10k R4 - 2.7k to 10k C1 - 1F C2 - 0.1F SDA SCL ISL29125 INT GND 3 FIGURE 1.

RADIATION PATTERN Page 5 of 17 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/W/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). 1 0 0 0 1 0 0 R/W DEVICE ADDRESS BYTE A7 A6 A5 A4 A3 A2 A1 A0 REGISTER ADDRESS BYTE D7 D6 D5 D4 D3 D2 D1 D0 DATA BYTE 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. FIGURE 7.

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. SIGNAL FROM MASTER DEVICE SIGNAL AT SDA SIGNALS FROM SLAVE DEVICE S T A R T DEVICE ADDRESS WRITE 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).

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.

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. TABLE 5. SENSING RANGES B3 RANGES (lux) 0 375 1 10,000 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.

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). TABLE 11.

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.

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. A 8000 D65 6000 4000 F2 2000 0 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. 0 20 40 60 80 100 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. COMPENSATION ADJUSTMENT (% RANGE) FIGURE 14. IR COMPENSATION VALUE 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 (EQ. 2) FN8424 Rev.3.00 Jan 13, 2017 Layout Route the supply and I2C traces as far as possible from all sources of noise. Use two power-supply decoupling capacitors, 1F and 0.1F, 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 +260C. A standard reflow soldering profile with a +260C maximum is recommended.
