• The inductivity of the wire from the LED pin (1,2 or 3) to the cathode of the LED needs to be
<20nH at If=200mA (e.g. max 2 – 3cm length of a wire). The cable length may be increased for
lower currents inversely proportional to forward current: cable length ∼ 1/forward current (e.g. max 8
- 12cm at If=50mA).
• Proposed size for the pull-up resistor is 560 Ohm

I2C interface
• 1.8V IO-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 7770 E6 operates always as slave, address is 0x38.
• Designed for the I2C-modes: Standard (100kHz), Fast (400kHz) and High Speed (3.4MHz)
• Combined format (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 single I2C traffic period. The register values are provided in a cyclic manner until master sends
the stop condition. E.g. if master uses block read and starts from register 0x8C, the slave returns
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
OFF
I
DD is below 2μA and the device is inactive. Other units may use the I2C bus without
any restrections; I/O pins and INT are in a high Z state. There is no sink current
through the LEDs.
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 SFH7770 E6. This mode can also be
used for Ambient Light Sensor and Proximity Sensor. Measurement repetition rate
and current through the LEDs are defined by the MCU. Measurement results can
be read from the data register, the status from the interrupt register.

If
VDD exceeds the threshold-voltage, the sensor will switch from OFF 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.

1)
The limits for the logic levels of SCL and SDA pins are in accordance with the I²C bus specification from NXP
(UM10204 „I²C bus specification and user manual“, Rev. 03 - 19 June 2007). The same limits are valid for the logic
levels of the interrupt pin (INT): the maximum level for logic „LOW“ level is 30% of the I/O voltage
level for logic „HIGH“ level is 70% of the I/O voltage VIO
VIO, the minimum
.
2)
Extended voltage range for I²C bus communication is only valid for standard- and fast-mode. Input levels are
internally referenced to 1.8V. So „LOW“ level threshold is 30% of 1.8V and „HIGH“ level threshold is 70% of 1.8V
regardless of the external I/O voltage VIO. Operating at VIO>2.0V can lead to minor timing violations to the I²C bus
specification from NXP concerning the minimum/maximum hold time requirement.

DC-offset of 0.5mA has to be added to LED current consumption during LED burst
2) Output signal of the Proximity Sensor
The sensitivity range of the Proximity Sensor is typ. 10 μW/cm2 to 2000 μW/cm2 . Within this range, the
data in the SFH 7770 E6 output register are available in an approximately logarithmic scale. The
advantage of the logarithmic scale is the possibility to cover a large range of distance without changing
the sensitivity settings of the sensor.
When the irradiance is below 10 μW/cm², the PS output signal exhibits noise which is typically below 40
output counts (see the dashed line in the graph below).
For irradiance higher than typ. 10μW/cm², the PS output signal increases monotonically.
The proximity signal is converted to a 8 bit signal.

The absolute resolution range of the ALS depends on the integration time. This can be set in register 0x26. Default
value is 100ms resulting in a resolution range of 0.3 lx ... 6500 lx. To access register 0x26, register 0x20 must first
be set to 0x01. After changing the integration time it is recomended to set register 0x20 back to 0x00. For a detailed
description please see page 11.

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 register 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 1000 ms results in a range of 0.03lx
to 650 lx with 0.01 lx resolution per count.

Proximity sensor Integration Time
Note: Register 0x27 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

for user access. Afterwards set the access bit of register 0x20 back to ’0’.
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 60 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 60 counts
(pseudo-logarithmic relationship).

When the measurement data are available in the register, the corresponding status bit (bit 6 for
ambient-light; bit 4, 2 and 0 for proximity) in register 0x8E is set to ’1’. When the measurement data have
been read by the MCU, the status bit 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, 3 and 5 are set when the measured PS value is above the threshold level (register 0x93...
0x95).
The status of register 0x8E will always be updated when a new measurement is available.

In Bit6/5 the source which triggers the interrupt is noted. Data from the status register (0x8E) are used.
In latched mode (set by bit3) this remains unchanged until the Interrupt register has been read by the
MCU, afterewards it is set to ’0’ automatically. In unlatched mode it is updated after every measurement.
The output polarity (pin 5 of the SFH7770 E6) can be changed by bit 2.
The interrupt can be triggered by the Ambient Light Sensor and / or by the Proximity Sensor; this can
be set by the Interrupt mode (bit 1/bit 0). When bit 1 and bit 0 are set to ’0’, the INT output is in the high
Z state (high impedance).
