TSL2584TSV

TSL2584TSV
Light-to-Digital Device
General Description
The TSL2584TSV is a very-high sensitivity light-to-digital
converter that transforms light intensity into a digital signal
output capable of direct I²C interface. The device combines one
broadband photodiode (visible plus infrared), one
infrared-responding photodiode, and a photopic
infrared-blocking filter on a single CMOS integrated circuit. Two
integrating ADCs convert the photodiode currents into a digital
output that represents the irradiance measured on each
channel. This digital output can be input to a microprocessor
where illuminance (ambient light level) in lux is derived using
an empirical formula to approximate the human eye response.
The TSL2584TSV supports a traditional level style interrupt that
remains asserted until the firmware clears it.

TSL2584TSV − Detailed Description
Detailed Description
The TSL2584TSV contains two integrating analog-to-digital
converters (ADC) that integrate currents from two photodiodes.
Integration of both channels occurs simultaneously. Upon
completion of the conversion cycle, the conversion result is
transferred to the Channel 0 and Channel 1 data registers. The
transfers are double-buffered to ensure that the integrity of the
data is maintained. After the transfer, the device automatically
begins the next integration cycle.
Communication with the device is accomplished through a
standard, two-wire I²C serial bus. Consequently, the
TSL2584TSV can be easily connected to a microcontroller or
embedded controller. No external circuitry is required for signal
conditioning. Because the output of the device is digital, the
output is effectively immune to noise when compared to an
analog signal.
The TSL2584TSV also supports an interrupt feature that
simplifies and improves system efficiency by eliminating the
need to poll a sensor for a light intensity value. The primary
purpose of the interrupt function is to detect a meaningful
change in light intensity. The concept of a meaningful change
can be defined by the user both in terms of light intensity and
time, or persistence, of that change in intensity. The device has
the ability to define thresholds above and below the current
light level. An interrupt is generated when the value of a
conversion exceeds either of these limits.

Note(s) and/or Footnote(s):
1. Optical measurements are made using small-angle incident radiation from light-emitting diode optical sources. Visible white LEDs
and infrared 850 nm LEDs are used for final product testing for compatibility with high-volume production.
2. The white LED irradiance is supplied by a white light-emitting diode with a nominal color temperature of 4000 K.
3. The 850 nm irradiance Ee is supplied by a GaAs light-emitting diode with the following typical characteristics: peak wavelength
λ p = 850 nm and spectral halfwidth Δλ½ = 42 nm.
4. The integration time Tint, is dependent on the internal oscillator frequency (f OSC ) and on the number of integration cycles (ATIME)
in the Timing Register as described in the register section. For nominal fOSC = 750 kHz, nominal Tint = 2.7 ms x ATIME.
5. 111x gain is affected by the line inductance between the VDD pin and the decoupling capacitor.

TSL2584TSV − Register Description
Interrupt Register (02h)
The Interrupt Register controls the extensive interrupt
capabilities of the device. The open-drain interrupt pin is active
low and requires a pull-up resistor to V DD in order to pull high
in the inactive state. The Interrupt Register provides control
over when a meaningful interrupt will occur. The concept of a
meaningful change can be defined by the user both in terms of
light intensity and time, or persistence of that change in
intensity. The value must cross the threshold (as configured in
the Threshold Registers 03h through 06h) and persist for some
period of time as outlined in Figure 19.
When a level Interrupt is selected, an interrupt is generated
whenever the last conversion results in a value outside of the
programmed threshold window. The interrupt is active-low and
remains asserted until cleared by writing an 11 in the
TRANSACTION field in the COMMAND register.

TSL2584TSV − Register Description
Interrupt Threshold Registers (03h-06h)
The Interrupt Threshold Registers store the values to be used
as the high and low trigger points for the comparison function
for interrupt generation. If the value generated by Channel 0
crosses below or is equal to the low threshold specified, an
interrupt is asserted on the interrupt pin. If the value generated
by Channel 0 crosses above the high threshold specified, an
interrupt is asserted on the interrupt pin. Registers THLLOW and
THLHIGH provide the low byte and high byte, respectively, of
the lower interrupt threshold. Registers THHLOW and THHHIGH
provide the low and high bytes, respectively, of the upper
interrupt threshold. The high and low bytes from each set of
registers are combined to form a 16-bit threshold value. The
interrupt threshold registers default to 00h on power up.

Note(s) and/or Footnote(s):
1. Since two 8-bit values are combined for a single 16-bit value for each of the high and low interrupt thresholds, the Byte protocol
should not be used to write to these registers. Any values transferred by the Byte protocol with the MSB set would be interpreted
as the COMMAND field and stored as an address for subsequent read/write operations and not as the interrupt threshold information
as desired. The Write Word protocol should be used to write byte-paired registers. For example, the THLLOW and THLHIGH registers
(as well as the THHLOW and THHHIGH registers) can be written together to set the 16-bit ADC value in a single transaction.

TSL2584TSV − Register Description
ADC Channel Data Registers (14h-17h)
The ADC Channel data are expressed as 16-bit values spread
across two registers. The ADC Channel 0 data registers,
DATA0LOW and DATA0HIGH provide the lower and upper bytes,
respectively, of the ADC value of Channel 0. Registers
DATA1LOW and DATA1HIGH provide the lower and upper bytes,
respectively, of the ADC value of Channel 1. All Channel data
registers are read-only and default to 00h on power up.

Note(s) and/or Footnote(s):
1. The Read Word protocol can be used to read byte-paired registers. For example, the DATA0LOW and DATA0HIGH registers (as well
as the DATA1LOW and DATA1HIGH registers) may be read together to obtain the 16-bit ADC value in a single transaction.
The upper byte data registers can only be read following a read
to the corresponding lower byte register. When the lower byte
register is read, the upper eight bits are strobed into a shadow
register, which is read by a subsequent read to the upper byte.
The upper register will read the correct value even if additional
ADC integration cycles end between the reading of the lower
and upper registers.

TSL2584TSV − Register Description
Manual Integration Timer Registers (18h-19h)
The Manual Integration Timer Registers provide the number of
cycles in 10.9 μs increments that occurred during a manual
start/stop integration period. The timer is expressed as a 16-bit
value across two registers. See CONTROL and TIMING Registers
for further instructions in configuring a manual integration. The
maximum time that can be derived without an overflow is
714.3ms.

Information
Soldering Information
The reflow profile specified here describes expected maximum
heat exposure of devices during the solder reflow process of
the device on a PCB. Temperature is measured at the top of the
device. Devices should be limited to one pass through solder
reflow profile. It is recommended after solder reflow that
underfill is used for increased robustness.

TSL2584TSV − Soldering & Storage Information
Storage Information
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.
Devices are dry packed in a sealed aluminized envelope called
a moisture-barrier bag with silica gel to protect them from
ambient moisture during shipping, handling, and storage
before use.
Floor Life
This package has been assigned a moisture sensitivity level of
MSL 1. As a result, the floor life of the devices removed from the
moisture barrier bag is unlimited from the time the bag was
opened, provided that the devices are stored under the
following conditions:
• Floor Life: Unlimited
• Ambient Temperature: < 30°C
• Relative Humidity: < 85%
If the floor life or the temperature/humidity conditions have
been exceeded, the devices must be rebaked prior to solder
reflow or dry packing.
Rebaking Instructions
When the shelf life or floor life limits have been exceeded,
rebake at 50°C for 12 hours.
