Device Address
Register Addresses
The VCNL4000 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.
VCNL4000 has twelve user accessible 8 bit registers. The
register addresses are 80h (register #0) to 8Bh (register #11).
REGISTER FUNCTIONS
Register #0 Command Register

Description
config_lock
Read only bit. Value = 1
als_data_rdy
Read only bit. Value = 1 when ambient light measurement data is available in the result registers. This bit
will be reset when one of the corresponding result registers (reg #5, reg #6) is read.
prox_data_rdy
Read only bit. Value = 1 when proximity measurement data is available in the result registers. This bit will
be reset when one of the corresponding result registers (reg #7, reg #8) is read.
als_od
R/W bit. Starts a single on-demand measurement for ambient light. If averaging is enabled, starts a
sequence of readings and stores the averaged result. Result is available at the end of conversion for
reading in the registers #5(HB) and #6(LB).
prox_od
R/W bit. Starts a single on-demand measurement for proximity.
Result is available at the end of conversion for reading in the registers #7(HB) and #8(LB).
Notes
• After a proximity start command [prox_od] a WAIT time of ≥ 400 μs should be inserted before any read out commands.
• With setting bit 3 and bit 4 at the same write command, a simultaneously measurement of ambient light and proximity is done.

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.
Modulation dead Time
R/W bits. Setting a dead time in evaluation of IR signal at the slopes of the IR signal.
This function is for reducing of possible disturbance effects.
This function is reducing signal level and should be used carefully.
Note
• The settings for best performance will be provided by Vishay. With first samples this is evaluated to: delay time = 4 and dead time = 1, with
that register #10 should be programmed with: 129 (dez.)
Register #11 Ambient IR Light Level Register
Register address = 8Bh.
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.
Example: read register “Ambient Light Result Register” #5 and #6:
Addressing:command: 26h, 85h (VCNL4000_I2C_Bus_Write_Adr., Ambient Light Result Register #5 [85])
Read register #5:command: 27h, data (VCNL4000_I2C_Bus_Read_Adr., {High Byte Data of Ambient Light Result Register #5 [85])}
Read register #6:command: 27h, data (VCNL4000_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).

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 (bit7 of reg #4 = 1):
In continuous conversion mode the single measurements are done directly subsequent after each other.
