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 (O=615 nm),
green (O=530 nm), blue (O=460 nm), and infrared (O=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 integra-
tion 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 NjA typ.
Small package (WL-CSP: wafer level-chip size package)
Internal infrared-cut ¿lter
Wide dynamic range (Low gain: 1 to 10 klx)
01 Feature
I2C interface-compatible to allow direct connection to micro-controller
The sensor supports the I2C interface and so can exchange data
with the micro-controller using two signal lines jointly usable with
other devices. The digital output makes it easy to install into elec-
tronic devices such as cell phones and Àat-panel TVs whose micro-
controller is compatible with the I2C interface. The sensor supports
I2C Fast mode (400 kHz) and operates on 2.25 to 3.63 V.
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
02 Feature
WL-CSP makes the device even smaller and highly reliable
The WL-CSP measures only 1.18 × 1.68 × 0.58 mm and lead-free
reÀow solder (260 °C) can be used.
