The TCS3414 of ams: thé Digital Color Sensor of the “HELIOS”

Intelligent Light Sensors for every vertical application
The TCS3404/3414FN digital color light sensor is designed to accurately derive the color chromaticity and illuminance (intensity) of ambient light and provide a digital output with 16-bits of resolution.
The device includes an 8 x 2 array of filtered photodiodes, analog-to-digital converters, and control functions on a single monolithic CMOS integrated circuit.
Of the 16 photodiodes, 4 have red filters, 4 have green filters, 4 have blue filters, and 4 have no filter. With the advanced patent pending in-package trim capability, device-to-device and system-to-system tolerance can be minimized allowing very precise repeatability to be attained.

Four parallel analog-to-digital converters (ADC) transform the photodiode currents to a SMBus (TCS3404) or I2C (TCS3414) digital output that, in turn, can be input to a microprocessor. A single SMB-Alert style interrupt (TCS3404) as well as a single traditional level-style interrupt (TCS3414) can be dynamically configured for any one of the four channels including a corresponding high/low threshold setting. The interrupt will remain asserted until the firmware clears the interrupt.
