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).
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 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.
In the TCS3210, the light-to-frequency converter reads a 4 x 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 x 110 μm in size and are on
134-μm centers.
