Digital Color Sensors

The TCS3404 and TCS3414 digital color light sensors are

designed to accurately derive the color chromaticity and

illuminance (intensity) of ambient light and provide a digital

output with 16-bits of resolution. The devices include an

8 × 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 (clear). 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.

A synchronization input (SYNC) provides precise external

control of sensor integration allowing the internal conversion

cycles to be synchronized to a pulsed light source. Furthermore,

the synchronization feature supports the following advanced

modes of operation to maximize flexibility across a broad range

of hardware systems:

1. sync for one internal-time cycle, and

2. accumulate for specified number of pulses.

The device also supports free-running and

serial-bus-controlled integration modes if precise coupling

between the sensor and light source is not required.

Four parallel analog-to-digital converters (ADC) transform the

photodiode currents to an SMBus (TCS3404) or I2C (TCS3414)

digital output that, in turn, can be input to a microprocessor.

The RGB values can be read in a single read cycle to minimize

the number of read command protocols defined in the

communication interface. The slave address for this device is

39h (0111001b). 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.

The TCS3404/14 devices can help

1. automatically adjust the display brightness of a

backlight to extend battery, increase lamp life, and

provide optimum viewing in diverse lighting

conditions,

2. white-color balance display panel and/or captured

images in diverse lighting conditions, and

3. manage RGB LED backlighting to maintain color

consistency over a long period of time.
