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. Ordering Information and Content Guide appear at end of datasheet.

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. ams Datasheet [v1-05] 2015-Sep-01 Page 3 Document Feedback TSL2584TSV − Pin Assignment The TSL2584TSV pin assignments are described below.

Example: For a 1 × 2.7-ms interval, 0xFF should be written. For 2 × 2.7-ms intervals, 0xFE should be written. The maximum integration time is 688.5 ms (00000001b).

Page 16 Document Feedback ams Datasheet [v1-05] 2015-Sep-01 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.

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. Figure 22: Interrupt Threshold Registers Register Address Bits Description THLLOW 3h 7:0 ADC Channel 0 lower byte of the low threshold THLHIGH 4h 7:0 ADC Channel 0 upper byte of the low threshold THHLOW 5h 7:0 ADC Channel 0 lower byte of the high threshold THHHIGH 6h 7:0 ADC Channel 0 upper byte of the high threshold 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. ams Datasheet [v1-05] 2015-Sep-01 Page 19 Document Feedback TSL2584TSV − Register Description Analog Register (07h) The Analog Register provides eight bits of control to the analog block.

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.

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. ams Datasheet [v1-05] 2015-Sep-01 Page 21 Document Feedback 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.

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. ams Datasheet [v1-05] 2015-Sep-01 Page 27 Document Feedback TSL2584TSV − Ordering & Contact Information Ordering & Contact Information Figure 33: Ordering Information Ordering Code Interface Delivery Form Delivery Quantity TSL2584TSV I²C Vbus = 1.8 V Interface Tape & Reel 3500 pcs/reel Buy our products or get free samples online at: www.ams.com/ICdirect Technical Support is available at: www.ams.com/Technical-Support Provide feedback about this document at: www.ams.com/Document-Feedback For further information and requests, e-mail us at: [email protected] For sales offices, distributors and representatives, please visit: www.ams.com/contact Headquarters ams AG Tobelbaderstrasse 30 8141 Unterpremstaetten Austria, Europe Tel: +43 (0) 3136 500 0 Website: www.ams.com Page 28 Document Feedback ams Datasheet [v1-05] 2015-Sep-01 TSL2584TSV − RoHS Compliant & ams Green Statement RoHS Compliant & ams Green Statement RoHS: The term RoHS compliant means that ams AG products fully comply with current RoHS directives. Our semiconductor products do not contain any chemicals for all 6 substance categories, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, RoHS compliant products are suitable for use in specified lead-free processes. ams Green (RoHS compliant and no Sb/Br): ams Green defines that in addition to RoHS compliance, our products are free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material).
