[v1-01] 2016-Dec-08 Document Feedback AS7221 Calibrated XYZ Chromatic Manager for Network Enabled Smart Lighting The AS7221 Smart Lighting Mana ger device is part of the ams Cognitive Lighting™ family of products that enable lights to be “aware” and adapt to their surroundings, autonomously adapting to human lighting and energy conservation needs. The device is equipped with an advanced Cognitive Lighting Engine (CLE) to optimize, chromatic white/color tuning, daylight harvesting and lumen maintenance via a combination of PWM and/or 0-10V controls with dimming ballasts. Direct connection to a local sensor network (LSN), enables connectivity with standard occupancy sensors, dimmers or communications bridges. AS7221 XYZ chromatic white/color sensing provides mapping to x, y (z) of the CIE 1931 2-dimensional color gamut coordinates and scales the coordinates to the CIE 1976 u’v’ coordinate system. The AS7221 integrates standard observer filters into standard silicon via nano-optic deposited interference filters which deliver high-stability over time and temperature. The LGA package includes a built in aperture to control light entering the sensor array. Integrated intelligence enables lifetime CCT calibration to within 2-4 Macadam steps. The AS7221 connects to standard 0-10V dimmers inputs and drives 0-10V dimming ballasts/ drivers to enable a highly cost-effective white tunable current-steering luminaire design with a single-channel constant current ballast. Direct PWM inputs can also interface to standard LED drivers or multi-channel ballasts for constant voltage LED lighting architectures. A UART interface is provided for configuration, control and management of the CLE. This UART interface responds to simple Smart Lighting Set commands. Ordering Information and Content Guide appear at end of datasheet. General Description

[v1-01] 2016-Dec-08 Document Feedback AS7221 − Detailed Description AS7221 Smart Lighting Manager - Overview The Cognitive Light Engine (CLE) is the “brains” of the Smart Lighting Manager. The CLE constantly processes information from the calibrated XYZ chromatic white/color sensor, network access and inputs while contro lling outputs. AS7221 initial setup and ongoing parameter storage is automatically done by software within the required external serial flash memory, via SPI bus. A luminaire solution for chromatic white/color maintenance with lumen maintenance requires only the AS7221. A luminaire solution with chromatic white color/maintenance, lumen maintenance and daylighting requir es just the addition of an ams TSL4531 single chip ambient light sensor, connected via I²C. Refer to the table in the Figure below. Overall AS7221 timing generation uses an on chip 16MHz temperature compensated oscillator for master clock timing. Refer to the separate AS7221 User Guide as well as the ams Smart Lighting Command Set document for additional usage and setup information.

Document Feedback [v1-01] 2016-Dec-08 AS7221 − Detailed Description XYZ Chromatic White Color Sensor The XYZ chromatic white/color sensor, part of the AS7221 Cognitive Light Engine (CLE), is a next-generation digital color sensor device. The sensor contains an integrating analog-to-digital converter (16-bit resolution ADC), which integrates current from photodio des. Upon completion of the conversion cycle, the result is transferred to the corresponding data registers. Transfers are double-buffered to ensure integrity of the data is maintained. Standard observer interference filters realize the XYZ response, which enables both a no life-time drift and very high temperature stability. Note the AS7221 LGA package contains an internal aperture that provides a package field of view (PFOV) of ± 20.5°. External optics can be used as needed to expand or reduce this built in PFOV. AS7221 Inputs Figure 16: VDDHV Based Settings for Inputs Note(s): 1. For VDDHV <= 3.6V, VDDHV and VDD should be tied together. 2. With external dividers connected to 0-10V in puts, the max voltage to the device input is 2V. For the AS7221, dimming can be accomplished from either the input pin (0_10V_DIM) or network command via the UART. For network commanded dimming, using the AS7221 Smart Lighting Command set, the UART interface is used. Local hardware inputs can be provided by, for example, a slide control dimmer. The 0-10V DIM analog input signal is downscaled by the AS7221 with an internal voltage divider and converted to a 10 bit digital value, 0V=full dimming, 10V=no dimming. When using the internal voltage divider the voltage at the VDDHV pin has to be higher than 10V. If a second supply is not available, VDDHV and VDD are tied together and the downscale has to be done by an external resistor divider. The maximum range in the downscaled input is limited to 2V. Hence to accept a full range 10V signal the input resistor divider has to be 5:1 ratio. Dependent on the level at pin VDDHV the Smart Lighting Manager automatically selects either the internal or the external voltage divider. Refer to the Figures above and below. If the 0_10V_DIM pin is not used, an external resister pull-up connecting it to VDDHV is recommended.

Document Feedback [v1-01] 2016-Dec-08 AS7221 − Detailed Description Refer to the Figure above. When pulled down for more than 100ms the SYNC/RESN pin will reset the AS7221 Smart Lighting Manager. In this case the push-button “overrides” the output of the opto-coupler. Therefore a resistor should be placed in series with the opto-coupler. AS7221 Outputs The AS7221 outputs, used to control dimming and LED warm/cool strings, can be configured as either three PWM outputs, two PWMs and one analog output, or two PWMs. The PWMs are 12 bit and factory set to 888 Hz. Refer to the Figure below. The three PWM outputs, PWM_1, PWM_2 and PWM_3 all switch with the same frequency, but ar e not simultaneous for better EMI performance. The PWM_1 output can be set to either analog (0-VDDHV) or digital (0-VDDHV) dimming. Analog dimming range is 10-100%. Digital Dimming range is 1-100%. PWM2 and PWM3 are used for cool white and warm white LED color controlling. Either string can be warm or cool as the AS7221 automatically configures string color type. Range is 0-100% for both PWM2 and PWM3. To set the desired device operat ion MODE use the appropriate R MODE resistor, also shown in the Figure below. Figure 19: Outputs Note(s): 1. For VDDHV>10.5, output max is 10V, else output max tracks VDDHV. Indicator LED An LED, connected to pin LED_IND, is used to indicate programming progress of the device. During programming of the AS7221 via an external SD card the indicator LED starts. When programming is finished the indicator LED is off. The LED_IND pin is set for 1mA operation by the AS7221 factory firmware, and is not under user control.

[v1-01] 2016-Dec-08 Document Feedback AS7221 − Detailed Description I²C Read Access Random, Sequential and Current Address Read are used to read data from the slave. Figure 25: I²C Random Read Random Read and Sequential Read are combined formats. The repeated START condition is used to change the direction after the data transfer from the master. The word address transfer is initiated with a START condition issued by the master while the bus is idle. The START condition is followed by the device-write address and the word address. In order to change the data direction a repeated START condition is issued on the 1st SCL pulse after the acknowledge bit of the word address transfer. After the reception of the device-read address, the slave be comes the transmitter. In this state the slave transmits register data located by the previous received word address vector. The master responds to the data byte with a not-acknowledge, and issues a STOP condition on the bus. S SW A WA Data N PA WA++ S r SR A read WA++
Document Feedback [v1-01] 2016-Dec-08 AS7221 − Detailed Description Figure 26: I²C Sequential Read I²C Sequential Read: Shows the format of an I²C sequential read access. Sequential Read is the extended form of Random Read, as more than one register-data bytes are transferred subsequently. In difference to the Random Read, for a sequential read the transferred register-data bytes are responded by an acknowledgement from the master. The number of data bytes transferred in one sequence is unlimited (consider the behavior of the word-address counter). To terminate the transmission the master has to send a not-acknowledge following the last data byte and generate the STOP condition subsequently.

[v1-01] 2016-Dec-08 Document Feedback AS7221 − Soldering & Storage Information Manufacturing Process Considerations The AS7221 package is compatible with standard reflow no-clean and cleaning processes including aqueous, solvent or ultrasonic techniques. However, as an open-aperture device, precautions must be taken to avoid particulate or solvent contamination as a result of any manufacturing processes, including pick and place, reflow , cleaning, integration assembly and/or testing. Temporary covering of the aperture is allowed. To avoid degradation of accuracy or performance in the end product, care should be taken that any temporary covering and associated sealants/debris are th oroughly removed prior to any optical testing or final packaging. 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. To ensure the package contains the smallest amount of absorbed mois ture possible, each device is baked prior to being dry packed for shipping. Devices are dry packed in a sealed aluminized envelope called a moisture-barrier bag with sili ca gel to protect them from ambient moisture during shipping, handling, and storage before use. Shelf Life The calculated shelf life of the device in an unopened moisture barrier bag is 12 months from the date code on the bag when stored under the following conditions:
- Shelf Life: 12 months
- Ambient Temperature: <40°C
- Relative Humidity: <90% Rebaking of the devices will be required if the devices exceed the 12 month shelf life or the Humidity Indicator Card shows that the devices were exposed to conditions beyond the allowable moisture region. Floor Life The module has been assigned a moisture sensitivity level of MSL 3. As a result, the floor life of devices removed from the moisture barrier bag is 168 hours from the time the bag was opened, provided that the devices are stored under the following conditions:
- Floor Life: 168 hours
- Ambient Temperature: <30°C
- Relative Humidity: <60%
Document Feedback [v1-01] 2016-Dec-08 AS7221 − Soldering & Storage Information 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.
