Color sensor
S11059-01WT
I2C interface-compatible color sensor
The S11059-01WT is a color sensor that supports the I2C (inter-integrated circuit) interface. It is sensitive to red ( =615 nm), green ( =530 nm), blue ( =460 nm), and infrared ( =855 nm) light, and outputs detected results as 16-bit digital data for each color. The photodiode for each color is automatically switched sequentially to perform measurements. The sensitivity and integration time can be adjusted so that light measurements can be performed over a wide range.
Features
I2C interface compatible Sequential measurements of red, green, blue, and infrared light 2-step sensitivity switching (sensitivity ratio 1 : 10) Sensitivity adjustment by setting the integration time Low voltage (2.5 V or 3.3 V) operation Low current consumption: 75 A typ. Small package (WL-CSP: wafer level-chip size package) Internal infrared-cut lter Wide dynamic range (Low gain: 1 to 10 klx) Feature
Applications
LCD backlight adjustment for cell phones, notebook PC, etc. Energy-saving sensor for large-size TV, etc. Various types of light detection or color adjustment
The sensor supports the
01 I C interface-compatible to allow direct connection to micro-controller

Feature
interface and so can exchange data
The WL-CSP measures only 1.18 × 1.68 × 0.58 mm and lead-free re ow solder (260 °C) can be used.
02 WL-CSP makes the device even smaller and highly reliable
with the micro-controller using two signal lines jointly usable with other devices. The digital output makes it easy to install into electronic devices such as cell phones and at-panel TVs whose microcontroller is compatible with the I2C interface. The sensor supports I2C Fast mode (400 kHz) and operates on 2.25 to 3.63 V.

Compensation method for sensitivity variation
1. Power on 2. Power on reset, initialization 3. ADC reset enable, standby disable 4. Measurement condition setting Gain, manual setting mode, integration time
Sensitivity variation can be decreased using the compensation coefficient which is calculated from the integration time measurement result. Explanation of compensation method is shown as follows.
Integration time measurement method
In case of integration time measurement, it is necessary to set manual setting mode. The integration time measurement starts after “ADC reset” disabled. To measure the nishing integration time (measurement) Tmeas, check “Standby monitor” bit until it becomes to “1”.
5. ADC reset disable 6. Measurement start (integration time)
Compensation method
The sensitivity compensation that used integration time is as follows:
K=
Tset Tmeas
No
Standby monitor = “1”? Yes
S' = S · K
K : compensation coef cient Tset : integration time (setting) Tmeas: integration time (measurement) S : photo sensitivity (measurement) S’ : photo sensitivity (compensation)
7. Measurement end (integration time)
8. Data read out
Measurement accuracy of integration time
9. Compensation
The measurement minimum resolution of Tmeas is de ned by the looping duration (Tunit). In case of default setting, the Tset is 2184 ms and assuming the Tunit to 7.8 ms, the accuracy of integration time is calulated by following formula.
Tunit 7.8 × 100 = × 100 = 0.36% Tset 2184
The speci cation of compensated sensitivity is de ned as 0.36% accuracy.
