TCS3200, tcs3210 programmable color light-to-frequency converter taos099a ? august 2011 7 the lumenology company copyright 2011, taos inc. www.taosinc.com application information power supply considerations power-supply lines must be decoupled by a 0.01-f to 0.1-f capacitor with short leads mounted close to the device package. input interface a low-impedance electrical connection between the device oe pin and the device gnd pin is required for improved noise immunity. all input pins must be either driven by a logic signal or connected to vdd or gnd ? they should not be left unconnected (floating). output interface the output of the device is designed to drive a standard ttl or cmos logic input over short distances. if lines greater than 12 inches are used on the output, a buffer or line driver is recommended. a high state on output enable (oe) places the output in a high-impedance state for multiple-unit sharing of a microcontroller input line. power down powering down the sensor using s0/s1 (l/l) will cause the output to be held in a high-impedance state. this is similar to the behavior of the output enable pin, however powering down the sensor saves significantly more power than disabling the sensor with the output enable pin. photodiode type (color) selection the type of photodiode (blue, green, red, or clear) used by the device is controlled by two logic inputs, s2 and s3 (see table 1). output frequency scaling output-frequency scaling is controlled by two logic inputs, s0 and s1. the internal light-to-frequency converter generates a fixed-pulsewidth pulse train. scaling is accomplished by internally connecting the pulse-train output of the converter to a series of frequency dividers. divided outputs are 50%-duty cycle square waves with relative frequency values of 100%, 20%, and 2%. because division of the output frequency is accomplished by counting pulses of the principal internal frequency, the final-output period represents an average of the multiple periods of the principle frequency. the output-scaling counter registers are cleared upon the next pulse of the principal frequency after any transition of the s0, s1, s2, s3, and oe lines. the output goes high upon the next subsequent pulse of the principal frequency, beginning a new valid period. this minimizes the time delay between a change on the input lines and the resulting new output period. the response time to an input programming change or to an irradiance step change is one period of new frequency plus 1 s. the scaled output changes both the full-scale frequency and the dark frequency by the selected scale factor. the frequency-scaling function allows the output range to be optimized for a variety of measurement techniques. the scaled-down outputs may be used where only a slower frequency counter is available, such as low-cost microcontroller, or where period measurement techniques are used. ams ag technical content still valid
TCS3200, tcs3210 programmable color light-to-frequency converter taos099a ? august 2011 8 copyright 2011, taos inc. the lumenology company www.taosinc.com application information measuring the frequency the choice of interface and measurement technique depends on the desired resolution and data acquisition rate. for maximum data-acquisition rate, period-measurement techniques are used. output data can be collected at a rate of twice the output frequency or one data point every microsecond for full-scale output. period measurement requires the use of a fast reference clock with available resolution directly related to reference clock rate. output scaling can be used to increase the resolution for a given clock rate or to maximize resolution as the light input changes. period measurement is used to measure rapidly varying light levels or to make a very fast measurement of a constant light source. maximum resolution and accuracy may be obtained using frequency-measurement, pulse-accumulation, or integration techniques. frequency measurements provide the added benefit of averaging out random- or high-frequency variations (jitter) resulting from noise in the light signal. resolution is limited mainly by available counter registers and allowable measurement time. frequency measurement is well suited for slowly varying or constant light levels and for reading average light levels over short periods of time. integration (the accumulation of pulses over a very long period of time) can be used to measure exposure, the amount of light present in an area over a given time period. pcb pad layout suggested pcb pad layout guidelines for the d package are shown in figure 6. 2.25 6.90 4.65 1.27 0.50 notes: a. all linear dimensions are in millimeters. b. this drawing is subject to change without notice. figure 6. suggested d package pcb layout ams ag technical content still valid
