Color sensor TCS3200

Color sensor TCS3200 is a programmable color light-to-frequency converter that combines configurable silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). In the TCS3200 sensor, the light-to-frequency converter reads an 8 x 8 array of photodiodes. Sixteen photodiodes have blue filters, 16 photodiodes have green filters, 16 photodiodes have red filters, and 16 photodiodes are clear with no filters. The full-scale output frequency can be scaled by one of three preset values via two control input pins. Digital inputs and digital output allow direct interface to a microcontroller or other logic circuitry. An output enables (OE) places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line.

The four types (colors) of photodiodes are interdigitated to minimize the effect of non-uniformity of incident irradiance. All photodiodes of the same color are connected in parallel. Pins S2 and S3 (photodiode type selection) are used to select which group of photodiodes (red, green, blue, clear) are active. Similarly, the output frequency scaling selection can be carried out through pins S0 and S1. TCS3200 (available in a SOIC-8 package with part number TCS3200D) is designed for single-supply operation and can be powered from dc 2. 7 to 5.5 volts.
