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
