Digital color sensor
S11012-01CR
12-bit digital output
The S11012-01CR is a digital color sensor sensitive to red (λ=615 nm), green (λ=540 nm) and blue (λ=465 nm) regions of the
spectrum. Detected signals are serially output as 12-bit digital data. Built-in three 12-bit registers allow simultaneous measurement
of RGB three colors. Sensitivity level is adjustable in two steps to cover a wide photometric range.

Feature
02
Simultaneous measurement of RGB three colors
Light signals detected by the photodiode are amplified and convert-
ed into 12-bit digital signals. An amplifier is also formed for each of
the RGB photodiode elements arrayed in the mosaic pattern, allow-
ing simultaneous accurate measurement of the RGB components of
incident light.
The photodiode consists of 9 × 9 elements arrayed in a mosaic
pattern. Each element has an on-chip
fi
lter that it sensitive to one
color of light, either red (λp=615 nm), green (λp=540 nm) or blue
(λp=465 nm).

2-step sensitivity switching
To enable measurement over a wide range of illuminance, the photodiode sensitivity can be selected from two setting modes (high sensitivity
mode and low sensitivity mode). The photodiode photosensitive area used to detect light differs depending on which sensitivity mode is selected
(high sensitivity mode: 9 × 9 elements, low sensitivity mode: 3 × 3 elements in center).

Operating sequence
(1) Set the Gate terminal and CK terminal to “Low”.
(2) Select the desired sensitivity with the Range terminal.
(3) Set the Gate terminal from “Low” to “High”, to start integrating the light intensity.
(4) After the desired integration time (tg) has passed, set the Gate terminal from “High” to “Low” to end the light intensity integration.
(5) Measurement data is output from the Dout terminal by inputting 36 CK pulses to the CK terminal.
Note 1: A total of 36 CK pulses are required to read out 3-color measurement data. Red data is output by the first 12 pulses,
green data by the next 12 pulses, and blue data by the last 12 pulses. Measurement data is output from the LSB side.
Note 2: Measurement data changes at the CK pulse rising edge.
Note 3: Do not switch the Range terminal during integration time (tg).
