TCS3404, TCS3414

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 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 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:
sync for one internal-time cycle, and
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
automatically adjust the display brightness of a backlight to extend battery, increase lamp life, and provide optimum viewing in diverse lighting conditions,
white-color balance display panel and/or captured images in diverse lighting conditions, and
manage RGB LED backlighting to maintain color consistency over a long period of time.

TCS3404, TCS3414 − General Description

These devices are also ideal in controlling keyboard illumination in low ambient light conditions. Chromaticity coordinates x,y can be used to derive color temperature for the purpose of white-color balancing of displays and/or captured images. Illuminance, in lux, can be used to approximate the human eye response of ambient light and to manage exposure control in digital cameras. The TCS3404/14 devices are ideal in notebook/tablet PCs, LCD monitors, flat-panel televisions, cell phones, and digital cameras. Additional applications include street light control, security lighting, sunlight harvesting, and automotive instrumentation clusters.

TCS3404, TCS3414 − Principles of Operation

Interrupt

Although the ADC channel data registers can be read at any time to obtain the most recent conversion value, in some applications, periodic polling of the device may not be desirable. For these types of applications, the device supports a variety of interrupt options allowing the user to configure the device to signal when a change in light intensity has occurred. High and low threshold registers allow a range of light levels to be defined, outside of which the device generates an interrupt. A persistence setting allows the user to specify a time duration that the measured value must remain outside of the defined range before generating an interrupt. The interrupt function can be assigned to any one of the four ADC color channels. See Interrupt Control Register 02h for more information on configuring the interrupt functions.

SMBus and I2C Protocols

Each Send and Write protocol is, essentially, a series of bytes. A byte sent to the TCS3404/14 with the most significant bit MSB equal to 1 will be interpreted as a COMMAND byte. The lower four bits of the COMMAND byte form the register select address see Figure 24 , which is used to select the destination for the subsequent byte s received. The TCS3404/14 responds to any Receive Byte requests with the contents of the register specified by the stored register select address. The TCS3404/14 implements the following protocols of the SMB specification:
• Send Byte Protocol
• Receive Byte Protocol
• Write Byte Protocol
• Write Word Protocol
• Read Word Protocol
• Block Write Protocol
• Block Read Protocol

The TCS3404/14 implements the following protocols of the I2C specification:
• I2C Write Protocol
• I2C Read Combined Format Protocol

When an SMBus Block Write or Block Read is initiated see description of Command Register , the byte following the COMMAND byte is ignored but is a requirement of the SMBus specification. This field contains the byte count i.e. the number of bytes to be transferred . The TCS3404 SMBus device ignores this field and extracts this information by counting the actual number of bytes transferred before the Stop condition is detected.
ams Datasheet [v1-00] 2015-Nov-11

TCS3404, TCS3414 − Principles of Operation

When an I2C Write or I2C Read Combined Format is initiated, the byte count is also ignored but follows the SMBus protocol specification. Data bytes continue to be transferred from the TCS3414 I2C device to Master until a NACK is sent by the Master.

The data formats supported by the TCS3404 and TCS3414 devices are:
• Master transmitter transmits to slave receiver SMBus and I2C
• The transfer direction in this case is not changed.
• Master reads slave immediately after the first byte SMBus only
• At the moment of the first acknowledgment provided by the slave receiver the master transmitter becomes a master receiver and the slave receiver becomes a slave transmitter.
