Description

7 S2

The TCS3200 and TCS3210 programmable color

light-to-frequency converters that combine confi-

gurable silicon photodiodes and a current-to-fre-

quency converter on a single monolithic CMOS

integrated circuit. The output is a square wave

(50% duty cycle) with frequency directly propor-

tional to light intensity (irradiance).

TCS3210

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. Output enable (OE)

places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line.

In the TCS3200, the light-to-frequency converter reads an 8 × 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.

In the TCS3210, the light-to-frequency converter reads a 4 × 6 array of photodiodes. Six photodiodes have blue

filters, 6 photodiodes have green filters, 6 photodiodes have red filters, and 6 photodiodes are clear with no

filters.

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 are used to select which

group of photodiodes (red, green, blue, clear) are active. Photodiodes are 110 μm × 110 μm in size and are on

134-μm centers.
