I2C interface
• 1.8V I/O-logic level for SDA and SCL
• I/O-pins are open drain type and logic high level is set with external pull-up resistor
• SFH 7773 operates in slave mode with address 0x38.
• Designed for the I2C-modes: Standard (100 kb/s), Fast (400 kb/s) and High Speed (3.4 Mb/s)
• Combined format is supported (see I2C Bus specification UM10204 from NXP) for data reading
• Block READ and WRITE modes are available. In these modes several registers can be read or written
during a single I2C traffic period. Registers are returned in a cyclic manner until the bus master sends
the stop condition. E.g. if master uses block read and starts from register 0x8C, the slave returns the
following register values: 0x8C, 0x8D, 0x8E, 0x8F, 0x90, 0x91, 0x92, 0x93, 0x94 and so on until the
master sends stop condition.
• Interrupt pin (INT): open-drain output (like SDA and SCL)

Measurement modes
If VDD exceeds the threshold-voltage , the sensor will switch from OFF mode to STAND-BY mode. As
shown in the transition-diagram above it is possible to switch between all modes without any restriction.
The transition time between modes (ttrans) is < 10ms. The delay time between STAND-BY and start of
measurement is max. 10ms for the ambient light sensor.
OFF IDD is below 2μA and the device is inactive. Other units may use the I2C bus without
any restrictions; I/O pins and INT are in Z state. There is no sink current through the
LED
STAND-BY This is the initial mode after power-up. IDD is below 5μA. No measurement is
performed. Device can be activated by I2C bus communication. Data registers can
be read and written. The data will be stored in the registers when the device goes
from TRIGGERED or FREE-RUNNING to STAND-BY.
TRIGGERED Every measurement is separately initiated by MCU. This mode can be used for
ambient light sensor and proximity sensor. Measurement data are available in the
registers after a defined delay time.
FREE-RUNNING Measurements are triggered internally by SFH7773. This mode can also be used
for ambient light sensor and proximity sensor. The measurement repetition rate and
current through the LED is defined by MCU. Measurement results can be read from
the data register, the status from the interrupt register.

1) Start-up sequence
The threshold limit where the device switches from OFF to STAND-BY mode is between VDD =1.4V and
VDD =2.0V.
Within 0.2s after exceeding the threshold voltage the device will switch from OFF to STAND-BY mode.
2) Output signal of the proximity sensor
The proximity sensor delivers output values in the range from 0 to 255, depending on integration time
settings. Low output values correspond to low irradiance of the sensor, while high values indicate high
irradiance. A threshold level for the proximity switch can be programmed via the I2C bus.

Note: Some of the following registers are marked as unused. They can still be accessed by block
write and read procedures.

Note: Register 0x26 is only accessible if access-bit ’0’ of register 0x20 is set to ’1’. Integration time
can then be changed. It is recommended to set access-bit ’0’ of the Integration Time Access register
afterwards back to ’0’. When reading or writing in block-read/-write mode, it is recomended to start at
reister 0x26 and stop at register 0x27, as there are other registers accessible which are not intended for
user access. Afterwards set the access bit of register 0x20 back to 0.
Note that the absolut ambient light sensor range depends on the integration time. I.e. default setting
range is 0.3 lx to 6.5 klx with resolution of 0.1 lx per count, whereas 10 ms results in a range of 3 lx to
65 klx with 1 lx resolution per count.

Note that the PS Integration Time sets the absolute PS signal count. I.e. an integration time of 1000 us
delivers a signal count which is around 50 counts higher compared to an integration time of 100 us. A
factor of 10 in signal level (resp. integration time) corresponds to around an increase of 50 counts
(pseudo-logarithmic relationship).

Ambient light measurement data (0x8C: LSB , 0x8D: MSB )
The result of the ambient light sensor is a 16bit word with MSB and LSB and is stored in two registers..
The binary data can be converted directly to decimal „lx“ values (max. 65535lx)
Status of measurement data for ambient light sensor (ALS) and proximity sensor (PS)
When the measurement is available in the register the corresponding statusbit (bit 6 for ambient-light;
bit 0 for proximity) in register 0x8E is set to „1“; when the measurement has been read by the MCU the
statusbit is automatically set back to „0“.
Bit 7 is set „1“ when the measured ALS value is outside the threshold level settings (register 0x96...
0x99). Bit 1 is set when the measured PS value is above the threshold level (register 0x93).
The status of register 0x8E will always be updated when a new measurement is available.

Interrupt register / INT output.
In Bit6/5 the source which triggers the interrupt is noted. Data from Status Register (0x8E) are used. In
latched mode (set by bit3) this remains unchanged until the Interrupt register has been read by the MCU,
afterwards it is set to 0 automatically. In unlatched mode it is updated after every measurement.
The Output polarity (pin 5 of the SFH7773) can be changed by bit 2.
Interrupt can be triggered by the ambient light sensor and / or by the proximity sensor; this can be set
in the Interrupt mode (bit 1/bit 0); when bit 1 and bit 0 is set to 0 the INT Output is in the Z state (high
impedance).

Cleaning / Washing
In general, OSRAM Opto Semiconductors does not recommend a wet cleaning process for components like the OSTAR
SMT, OSTAR Comp actand SFH777x 3in1 as the p ackage is not hermetically seale d. Due to the open de sign, all kind
of cleaning liquids can in filtrate the pac kage and cause a deg radation or a complete failure of the LED / ASIC. It is also
recommended to prevent penetration of organic substances from the environment which could interact with the hot
surfaces of the operating chips. Ultrasonic cleaning is generally not recommended for all types of LEDs (see also the
application note "Cleaning of LEDs"). As is standard for the electronic industry, OSRAM Opto Semiconductors
recommends using low-res idue or no-clean s older paste, so that PCB clean ing af ter soldering is no longer re quired. In
any case, all materials and methods should be tested beforehand in order to determine whether the component will be
damaged in the process.

The information describes the type of component and shall not be considered as assured characteristics. Due to the
special conditions of the manufacturing processes of Sensor, the typical data or calculated correlations of technical
parameters can only reflect statistical figures. These do not necessarily correspond to the actual parameters of each
single product, which could differ from the typical data and calculated correlations or the typical characteristic line. If
requested, e.g. because of technical improvements, these typ. data will be changed without any further notice.
Terms of delivery and rights to change design reserved. Due to technical requirements components may contain
dangerous substances. For information on the types in question please contact our Sales Organization.
Packing
Please use the recycling operators known to you. We can also help you – get in touch with your nearest sales office.
By agreement we will take packing material back, if it is sorted. You must bear the costs of transport. For packing
material that is returned to us unsorted or which we are not obliged to accept, we shall have to invoice you for any costs
incurred.
Components used in life-support devices or systems must be expressly authorized for such purpose! Critical
components 1 , may only be used in life-support devices or systems 2 with the express written approval of OSRAM OS.
1 A critical component is a component usedin a life-support device or system whose failure can reasonably be expected
to cause the failure of that life-support device or system, or to affect its safety or effectiveness of that device or system.
2 Life support devices or systems are intended (a) to be implanted in the human body, or (b) to support and/or maintain
and sustain human life. If they fail, it is reasonable to assume that the health of the user may be endangered.
