Description
The TSL230RD, TSL230ARD, and TSL230BRD programmable light-to-frequency converters combine a
configurable silicon photodiode and a current-to-frequency converter on single monolithic CMOS integrated
circuit. The output can be either a pulse train or a square wave (50% duty cycle) with frequency directly
proportional to light intensity. Device sensitivity is selectable in three ranges, providing two decades of
adjustment. The full-scale output frequency can be scaled by one of four preset values. All inputs and the output
are TTL compatible, allowing direct two-way communication with a microcontroller for programming and output
interface. The output enable (OE) places the output in the high-impedance state for multiple-unit sharing of a
microcontroller input line.
The devices are available with absolute output frequency tolerances of ±10% (TSL230BRD), ±15%
(TSL230ARD), and ±20% (TSL230RD). They have been temperature compensated for the ultraviolet-to-visible
light range of 320 nm to 700 nm and respond over the light range of 320 nm to 1050 nm. The devices are
characterized over the temperature range of −25°C to 70°C.

APPLICATION INFORMATION
Power-Supply Considerations
Power-supply lines must be decoupled by a 0.01-μF to 0.1-μF capacitor with short leads placed close to the
TSL230RD device package. A low-noise power supply is required to minimize jitter on output pulses.
Device Operational Details
The frequency at the output pin (OUT) is given by:
fO = fD + (Re) (Ee)
where:
fO
fD
Re
Ee
is the output frequency
is the output frequency for dark condition (Ee = 0)
is the device responsivity for a given wavelength of light given in kHz/(μW/cm2)
is the incident irradiance in μW/cm2
fD is an output frequency resulting from leakage currents. As shown in the equation above, this frequency
represents a light-independent term in the total output frequency fO. At very low light levels, this dark frequency
can be a significant portion of fO. The dark frequency is temperature dependent. For optimum performance of
any given device over the full output range, the value of fD should be measured (in the absence of light) and
later subtracted from subsequent light measurement (see Figure 1).
Input Interface
A low-impedance electrical connection between the device OE pin and the device GND pin is required for
improved noise immunity.
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.
Sensitivity Adjustment
Sensitivity is controlled by two logic inputs, S0 and S1. Sensitivity is adjusted using an electronic iris technique
— effectively an aperture control — to change the response of the device to a given amount of light. The
sensitivity can be set to one of three levels: 1×, 10×, or 100×, providing two decades of adjustment. This allows
the responsivity of the device to be optimized to a given light level while preserving the full-scale
output-frequency range. Changing of sensitivity also changes the effective photodiode area by the same factor.

TAOS054P − OCTOBER 2007
APPLICATION INFORMATION
Output-Frequency Scaling
Output-frequency scaling is controlled by two logic inputs, S2 and S3. Scaling is accomplished on chip by
internally connecting the pulse-train output of the converter to a series of frequency dividers. Divided outputs
available are divide-by 2, 10, 100, and 1 (no division). Divided outputs are 50 percent-duty-cycle square waves
while the direct output (divide-by 1) is a fixed-pulse-width pulse train. Because division of the output frequency
is accomplished by counting pulses of the principal (divide-by 1) frequency, the final-output period represents
an average of n (where n is 2, 10, or 100) periods of the principal 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, or 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 in the
divided output modes. In contrast with the sensitivity adjust, use of the divided outputs lowers 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 divide-by-1 or straight-through output can be used with a frequency counter, pulse
accumulator, or high-speed timer (period measurement). The divided-down outputs may be used where only
a slower frequency counter is available, such as a low-cost microcontroller, or where period measurement
techniques are used. The divide-by-10 and divide-by-100 outputs provide lower frequency ranges for high
resolution-period measurement.
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.
Using the divide-by-2 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 or from noise in the power supply.
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.

Moisture Sensitivity
Optical characteristics of the device can be adversely affected during the soldering process by the release and
vaporization of moisture that has been previously absorbed into the package molding compound. To prevent
these adverse conditions, all devices shipped in carrier tape have been pre-baked and shipped in a sealed
moisture-barrier bag. No further action is necessary if these devices are processed through solder reflow within
24 hours of the seal being broken on the moisture-barrier bag.
However, for all devices shipped in tubes or if the seal on the moisture barrier bag has been broken for 24 hours
or longer, it is recommended that the following procedures be used to ensure the package molding compound
contains the smallest amount of absorbed moisture possible.
For devices shipped in tubes:
1. Remove devices from tubes
2. Bake devices for 4 hours, at 90°C
3. After cooling, load devices back into tubes
4. Perform solder reflow within 24 hours after bake
Bake only a quantity of devices that can be processed through solder reflow in 24 hours. Devices can be
re-baked for 4 hours, at 90°C for a cumulative total of 12 hours (3 bakes for 4 hours at 90°C).
For devices shipped in carrier tape:
1. Bake devices for 4 hours, at 90°C in the tape
2. Perform solder reflow within 24 hours after bake
Bake only a quantity of devices that can be processed through solder reflow in 24 hours. Devices can be
re−baked for 4 hours in tape, at 90°C for a cumulative total of 12 hours (3 bakes for 4 hours at 90°C).
