APPLICATION INFORMATION
VCNL4010 is a cost effective solution of proximity and ambient light sensor with I2C bus interface. The standard serial digital
interface is easy to access “Proximity Signal” and “Light Intensity” without complex calculation and programming by external
controller. Beside the digital output also a flexible programmable interrupt pin is available.
1. Application Circuit
Fig. 12 - Application Circuit
(x) = Pin Number
Notes
• The interrupt pin is an open drain output. The needed pull-up resistor may be connected to the same supply voltage as the application
controller and the pull-up resistors at SDA/SCL. Proposed value R2 should be >1 kΩ , e.g. 10 kΩ to 100 kΩ.
Proposed value for R3 and R4, e.g. 2.2 kΩ to 4.7 kΩ, depend also on the I2C bus speed.
For detailed description about set-up and use of the interrupt as well as more application related information see AN: “Designing VCNL4010
into an Application”.
• IR_Cathode needs no external connection. The needed connection to the driver is done internally.

2. I2C Interface
The VCNL4010 contains seventeen 8 bit registers for operation control, parameter setup and result buffering. All registers are
accessible via I2C communication. Figure 13 shows the basic I2C communication with VCNL4010.
The built in I2C interface is compatible with all I2C modes (standard, fast and high speed).
I2C H-level range = 1.7 V to 5 V.
Please refer to the I2C specification from NXP for details.
Fig. 13 - Send Byte/Receive Byte Protocol
Device Address
The VCNL4010 has a fix slave address for the host
programming and accessing selection. The predefined 7 bit
I2C bus address is set to 0010 011 = 13h. The least
significant bit (LSB) defines read or write mode. Accordingly
the bus address is set to 0010 011x = 26h for write, 27h for
read.
Register Addresses
VCNL4010 has seventeen user accessible 8 bit registers.
The register addresses are 80h (register #0) to 90h
(register #16).
REGISTER FUNCTIONS
Register #0 Command Register
Register address = 80h
The register #0 is for starting ambient light or proximity measurements. This register contains 2 flag bits for data ready indication.
Note
• With setting bit 3 and bit 4 at the same write command, a simultaneously measurement of ambient light and proximity is done. Beside als_en
and/or prox_en first selftimed_en needs to be set. On-demand measurement modes are disabled if selftimed_en bit is set. For the
selftimed_en mode changes in reading rates (reg #4 and reg #2) can be made only when b0 (selftimed_en bit) = 0. For the als_od mode
changes to the reg #4 can be made only when b4 (als_od bit) = 0; this is to avoid synchronization problems and undefined states between
the clock domains. In effect this means that it is only reasonable to change rates while no selftimed conversion is ongoing.

Register #15 Proximity Modulator Timing Adjustment
Register address = 8Fh.
Note
• The settings for best performance will be provided by Vishay. With first samples this is evaluated to:
delay time = 0; dead time = 1 and prox. frequency = 0. With that register#15 should be programmed with 1 (= default value).
Register #16 Ambient IR Light Level Register
Register address = 90h.
This register is not intended to be used by customer.
3. IMPORTANT APPLICATION HINTS AND EXAMPLES
3.1 Receiver standby mode
In standby mode the receiver has the lowest current consumption of about 1.5 μA. In this mode only the I2C interface is active.
This is always valid, when there are no measurement demands for proximity and ambient light executed. Also the current sink
for the IR-LED is inactive, so there is no need for changing register #3 (IR LED current).
3.2 Data Read
In order to get a certain register value, the register has to be addressed without data like shown in the following scheme. After
this register addressing, the data from the addressed register is written after a subsequent read command.
Fig. 14 - Send Byte/Receive Byte Protocol
The stop condition between these write and read sequences is not mandatory. It works also with a repeated start condition.
Note
• For reading out 2 (or more) subsequent registers like the result registers, it is not necessary to address each of the registers separately. After
one read command the internal register counter is increased automatically and any subsequent read command is accessing the next
register.

Modulation delay time Proximity frequency Modulation dead time
Description
Modulation delay time
R/W bits. Setting a delay time between IR LED signal and IR input signal evaluation.
This function is for compensation of delays from IR LED and IR photo diode. Also in respect to the
possibility for setting different proximity signal frequency. Correct adjustment is optimizing measurement
signal level. ( DEFAULT = 0)
Proximity frequency
R/W bits. Setting the proximity IR test signal frequency
The proximity measurement is using a square IR signal as measurement signal. Four different values are
possible:
00 = 390.625 kHz (DEFAULT)
01 = 781.25 kHz
10 = 1.5625 MHz
11 = 3.125 MHz
Modulation dead time
R/W bits. Setting a dead time in evaluation of IR signal at the slopes of the IR signal. ( DEFAULT = 1)
This function is for reducing of possible disturbance effects.
This function is reducing signal level and should be used carefully.

Example: read register “Ambient Light Result Register” #5 and #6:
Addressing:command: 26h, 85h (VCNL4010_I2C_Bus_Write_Adr., Ambient Light Result Register #5 [85])
Read register #5:command: 27h, data (VCNL4010_I2C_Bus_Read_Adr., {High Byte Data of Ambient Light Result register #5
[85])}
Read register #6:command: 27h, data (VCNL4010_I2C_Bus_Read_Adr., {Low Byte Data of Ambient Light Result register #6
[86])}
3.3 Continuous Conversion Mode in Ambient Light Measurement
In the following is a detail description of the function “continuous conversion” (bit 7 of register #4)
Standard mode (bit 7 of reg #4 = 0):
In standard mode the ambient light measurement is done during a fixed time frame of 100 ms. The single measurement itself
takes actually only appr. 300 μs.
The following figures show examples of this measurement timing in standard mode using averaging function 2 and 8 as
examples for illustration (possible values up to 128).
Fig. 15 - Ambient Light Measurement with Averaging = 2;
Final Measurement Result = Average of these 2 Measurements
Fig. 16 - Ambient Light Measurement with Averaging = 8;
Final Measurement Result = Average of these 8 Measurements
Note
•≥ Independent of setting of averaging the result is available only after 100 ms.
Continuous conversion mode (bit 7 of register #4 = 1):
In continuous conversion mode the single measurements are done directly subsequent after each other.
See following examples in figure 17 and 18
