page 12 ams datasheet document feedback [v1-01] 2016-apr-13 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 235 a in color operation and 1ua during power down. functional description sleep start wait rgbc pon = 1 (0x80:b0) pon = 0 (0x80:b0)

ams datasheet page 29 [v1-01] 2016-apr-13 document feedback 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 12 months from the date code on the bag when stored under the following conditions: ? shelf life: 12 months ? ambient temperature: < 40 c ? relative humidity: < 90% rebaking of the devices will be required if the devices exceed the 12 month 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.
