The integrated IR blocking filter on the photodiode array eliminates the need for an external IR cut filter, ensuring accurate color measurement in the visible spectrum. The device communicates via I2C at up to 400kHz with a fixed 7-bit address of 0x29. Programmable integration time (2.4ms to 614ms) and gain settings allow optimization for different light conditions. An interrupt output with configurable upper and lower thresholds enables event-driven operation without continuous I2C polling. The FN-6 chip-scale package (2.0 x 2.4mm) is the smallest available for a full RGB color sensor.","working_principle":"The TCS34725FN uses a 4x4 array of photodiodes with different optical filters: 4 red-filtered, 4 green-filtered, 4 blue-filtered, and 4 clear (no filter) photodiodes. The IR blocking filter integrated on the die attenuates infrared wavelengths above approximately 700nm that would otherwise cause color measurement errors. During each integration cycle, the photodiode currents are integrated and converted by a 16-bit ADC. The integration time is programmable from 2.4ms (fast response) to 614ms (high sensitivity for low-light conditions). The gain setting (1x, 4x, 16x, or 60x) amplifies the photodiode signal before ADC conversion, extending the dynamic range. The I2C interface provides access to the 16-bit RGBC data registers, configuration registers, and interrupt threshold registers. The interrupt output can be configured to assert when any channel exceeds a programmable upper or lower threshold, with a persistence filter to prevent spurious triggers. The separate VDD (2.7-3.6V) and VDDIO (1.8V) supplies allow direct connection to 1.8V logic MCUs without level shifters.","pin_description":"\n
      Pin<\/th>Name<\/th>Type<\/th>Description<\/th><\/tr>\n
      1<\/td>VDD<\/td>Power<\/td>Supply voltage input. Operates from 2.7V to 3.6V (nominally 3.0V). Bypass with 0.1\u00b5F ceramic capacitor to GND placed as close to the pin as possible. Do not exceed 3.6V to prevent permanent damage. For 5V systems, use a level shifter or LDO regulator.<\/td><\/tr>\n

      3<\/td>GND<\/td>Ground<\/td>Ground reference. Connect to system ground plane. The exposed paddle (bottom of package) is also GND and must be soldered to the PCB for both electrical continuity and thermal dissipation.<\/td><\/tr>\n

      TCS34725FN pin assignment (FN-6 \/ Dual Flat No-Lead, top view, Pin 1 marked by dot): Pin 1 = VDD, Pin 2 = SCL, Pin 3 = GND, Pin 4 = NC, Pin 5 = INT, Pin 6 = SDA. The package is a tiny 2.0 x 2.4 x 0.65mm DFN with exposed thermal pad (GND) on the bottom. The I2C address is fixed at 0x29 and cannot be changed. Only two external components required: 0.1\u00b5F bypass cap and I2C pull-up resistors.<\/p>","application_scenarios":"
