Page 12 Datasheet, Public Document Feedback [v2-00] 2023-Feb-09 TCS3400 − Functional Description The TCS3400 device provides ambient light sensing and color temperature sensing. The internal state machine manages the operation of the device. It controls the ALS functionality and power down modes. Average po wer consumption is managed via control of variable endurance low power wait cycles. The interrupt feature improves sy stem efficiency by eliminating the need to poll the sensor. Two interrupt sources (ALS, ALS saturation) can activate the open drain output pin. Each interrupt source is enabled independently. ALS interrupts appear when upper or lower thresholds are exceeded for a consecutive number of sample readings. The advanced digital color light sensor portion of the TCS3400 contains a segmented circular photodiode array used for color measurements. This architecture provides stable color sensing independent of the in cident angle of light. Four integrating analog-to-digital converters (ADCs) integrate light energy from photodiodes simultaneously. Figure 18: Simplified ALS State Machine Communication with the device is accomplished through a fast (up to 400 kHz) two wire I²C serial bus for easy connection to a microcontroller or embedded controller. The device typically draws only 235μA in color operation and 1μA during power down. Functional Description Sleep Start Wait RGBC PON = 1 (0x80:b0) PON = 0 (0x80:b0)

Datasheet, Public Page 21 [v2-00] 2023-Feb-09 Document Feedback TCS3400 − Register Description RGBC Data Registers (0x94 - 0x9B) Clear, red, green, and blue data is stored as 16-bit values. The read sequence must read byte pairs (low followed by high) starting on an even address boundary (0x94, 0x96, 0x98, or 0x9A) inside the RGBC Data Regist er block. When the lower byte register is read, the upper eight bits are stored into a shadow register, which is read by a subsequent read to the upper byte. The upper register will read the correct value even if additional ADC integration cycles end betw een the reading of the lower and upper registers.

Datasheet, Public Page 23 [v2-00] 2023-Feb-09 Document Feedback TCS3400 − Power Supply Considerations Place a 1-μF low-ESR decoupling capacitor as close as possible to the V DD pin. Figure 34: Typical Application Hardware Circuit VBUS in the above figures refers to the I²C bus voltage which is either V DD or 1.8V. Be sure to apply the specified I²C bus voltage shown in the Ordering & Contact Information for the specific device being used. The I²C signals and the Interrupt are open-drain outputs and require pull-up resistors. The pull-up resistor (RP) value is a function of the I²C bus speed, the I²C bus voltage, and the capacitive load. The ams OSRAM EV M running at 400 kbit/s, uses 1.5-kΩ resistors. A 10-kΩ pull-up resistor (RPI) can be used for the interrupt line. Power Supply Considerations TCS3400 VDD 1 µF VBUS GND I/C INT SCL SDA RP RP RPIVoltage Regulator Cap sized per regulator specs

Page 28 Datasheet, Public Document Feedback [v2-00] 2023-Feb-09 TCS3400 − Soldering & Storage Information Moisture Sensitivity Optical characteristics of the device can be adversely affected during the soldering process by the release and vaporization of moisture that has been previous ly absorbed into the package. To ensure the package contains the smallest amount of absorbed moisture possible, each device is baked prior to being dry packed for shipping. Devices are dry packed in a sealed aluminized envelope called a moisture-barrier bag with silica gel to protect them from ambient moisture during shipping, handling, and storage before use. Shelf Life The calculated shelf life of the device in an unopened moisture barrier bag is 24 months from the date code on the bag when stored under the following conditions:
- Shelf Life: 24 months
- Ambient Temperature: < 40 °C
- Relative Humidity: < 90% Rebaking of the devices will be required if the devices exceed the 24 months shelf life or the Humidity Indicator Card shows that the devices were exposed to conditions beyond the allowable moisture region. Floor Life The FN package has been assigned a moisture sensitivity level of MSL 3. As a result, the floor life of devices removed from the moisture barrier bag is 168 hours from the time the bag was opened, provided that the devices are stored under the following conditions:
- Floor Life: 168 hours
- Ambient Temperature: < 30°C
- Relative Humidity: < 60% If the floor life or the temperature/humidity conditions have been exceeded, the devices must be rebaked prior to solder reflow or dry packing. Rebaking Instructions When the shelf life or floor life limits have been exceeded, rebake at 50 °C for 12 hours.
