I2C interface-compatible color sensor S11059-01WT www.hamamatsu.com The S11059-01WT is a color sensor that supports the I 2C (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 Applications 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 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 Feature FeatureI2C interface-compatible to allow direct connection to micro-controller WL-CSP makes the device even smaller and highly reliable01 02 The sensor supports the I 2C 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 À at-panel TVs whose micro- controller is compatible with the I 2C interface. The sensor supports I2C Fast mode (400 kHz) and operates on 2.25 to 3.63 V. The WL-CSP measures only 1.18 × 1.68 × 0.58 mm and lead-free reÀ ow solder (260 °C) can be used.

(infrared) Output data (infrared, MSB) 0A Output data (infrared, LSB) Adrs 00 bit 7: Asserting this bit to “1”, the ADC block is reset. The register data is not reset. To start the operation, set this bit to “0”. Adrs 00 bit 6: Asserting this bit to “1” the device goes into standby mode. The ADC block stops its operation. The register data is not reset. To start the operation, set this bit to “0”. Adrs 00 bit 5: This monitors auto standby function. “1” means standby mode. This is read only. Adrs 00 bit 3: Gain selection bit. “1” is high gain mode and “0” is low gain mode. This bit is selecting the photodiode area. The size ratio of high gain photodiode area and low gain photodiode area is 10 : 1. Therefore the gain ratio is 10 times from low to high. Adrs 00 bit 2: Asserting this bit to “1”, the device goes into manual setting mode. Deasserting this bit to 0, goes into ¿ xed period mode. In manual setting mode, the S11059-01WT automatically goes to standby mode after a measurement is made. In ¿ xed period mode, measurements are continuously repeated. Adrs 00 bit 1,0: These bits select the period of internal basis clock. The period is equal to integration time per color in ¿ xed period mode. “00” 44.8 ms, “11” is 368 ms. The integration time per color is set to multiple value (Adrs 01 & 02) with the period. Adrs 01 & 02: This is a multiple value setting in manual setting mode, and can be set to a minimum of 0x0000 and a maximum of 0 xFFFF (65535). This is used to set how far to expand the integration time per color which speci ¿ ed by “Integration time setting” (Tint). For example, if you want to set the integration time per color to 546 ms, set 175 —s by Tint=“00” and then set this register to N=3120 (0xC30).

Explanation of compensation method is shown as follows. In case of integration time measurement, it is necessary to set manual setting mode. The integra- tion time measurement starts after “ADC reset” disabled. To measure the ¿ nishing integration time (measurement) Tmeas, check “Standby monitor” bit until it becomes to “1”. Integration time measurement method 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 in- tegration time is calulated by following formula. Tunit Tset 7.8 2184× 100 = × 100 = 0.36% The speci¿ cation of compensated sensitivity is de¿ ned as 0.36% accuracy. Measurement accuracy of integration time 1. Power on 2.
