## Vishay Semiconductors 

## **RGBW Color Sensor With I[2] C Interface** 

## **FEATURES** 

- Package type: surface mount 

- Dimensions (L x W x H in mm): 2.0 x 1.25 x 1.0 

- Integrated modules: color sensor (RGBW) and signal conditioning IC 

- Filtron[TM] technology provides a spectrum matching real human eye responses 

- Supports low transmittance (dark) lens design 

- Fluorescent light flicker immunity 

- Provides 16-bit resolution for each channel (R, G, B, W) 

## **DESCRIPTION** 

VEML6040 color sensor senses red, green, blue, and white light and incorporates photodiodes, amplifiers, and analog / digital circuits into a single chip using CMOS process. With the color sensor applied, the brightness, and color temperature of backlight can be adjusted base on ambient light source that makes panel looks more comfortable for end user’s eyes. VEML6040’s adoption of Filtron[TM] technology achieves the closest ambient light spectral sensitivity to real human eye responses. 

VEML6040 provides excellent temperature compensation capability for keeping the output stable under changing temperature. VEML6040’s function are easily operated via the simple command format of I[2] C (SMBus compatible) interface protocol. VEML6040’s operating voltage ranges from 2.5 V to 3.6 V. VEML6040 is packaged in a lead (Pb)-free 4 pin OPLGA package which offers the best market-proven reliability.

## **APPLICATION INFORMATION** 

## **Pin Connection with the Host** 

VEML6040 integrates R, G, B, and W sensor together with I[2] C interface. It is very easy for the baseband (CPU) to access VEML6040 output data via I[2] C interface without extra software algorithms. The hardware schematic is shown in the following diagram. 

The 0.1 μF capacitor near the VDD pin is used for power supply noise rejection. The 2.2 k  s are suitable for the pull-up resistors of I[2] C.

## Vishay Semiconductors 

## **Digital Interface** 

The VEML6040 contains a CONF register (00h) used for operation control and parameter setup. Measurement results are stored in four separate registers, one each for red, green, blue, and white respectively (08h to 0Bh). All registers are accessible via I[2] C communication. Figure 8 shows the basic I[2] C communication with the VEML6040. Each of the registers in the VEML6040 are 16 bit wide, so 16 bit should be written when a write command is sent, and 16 bit should be read when a read command is sent. The built in I[2] C interface is compatible with I[2] C modes “standard” and “fast”: 100 kHz to 400 kHz

## **Note** 

- Please note the repeat start condition when data is read from the sensor. A stop condition should not be sent here. 

## **Slave Address and Function Description** 

VEML6040 uses 10h slave address for 7-bit I[2] C addressing protocol. VEML6040 has 16-bit resolution for each channel (R, G, B, and W) that provides sensitivity up to 0.0056 lux/step for G, which is advantageous under a low transmittance lens design (dark lens).

## **Data Access** 

Each of the R, G, B, and W result registers has a 16-bit resolution (2 bytes). One byte is the LSB and the other byte is the MSB. The host needs to follow the read word protocol as shown in figure 7. The data format shows as below.

- Data byte low represents LSB and data byte high represents MSB. 

The integration time settings result in the corresponding resolutions that are shown in table 6.

## **Data Auto-Memorization** 

VEML6040 keeps the last results read. These values will remain in the registers, and can be read from these registers, until the device wakes up and a new measurement is made. 

## **Lux and CCT Calculation** 

In order to use the results to calculate the lux or correlated color temperature, please refer to the “Designing the VEML6040 into an Application” application note (www.vishay.com/doc?84331).

## **RECOMMENDED IRON TIP SOLDERING CONDITION AND WARNING HANDLING** 

1. Solder the device with the following conditions: 

   - 1.1. Soldering temperature: 400 °C (max.) 

   - 1.2. Soldering time: 3 s (max.) 

2. If the temperature of the method portion rises in addition to the residual stress between the leads, the possibility that an open or short circuit occurs due to the deformation or destruction of the resin increases. 

3. The following methods: VPS and wave soldering, have not been suggested for the component assembly. 

4. Cleaning method conditions: 

   - 4.1. Solvent: methyl alcohol, ethyl alcohol, isopropyl alcohol 

   - 4.2. Solvent temperature < 45 °C (max.) 

   - 4.3. Time: 3 min (min.)
