DESCRIPTION AMBIENT LIGHT FUNCTION
VEML6030 is a high accuracy ambient light digital 16-bit • FiltronTM technology adaption: close to real human eye
resolution sensor in a miniature transparent 2 mm x 2 mm response
package. It includes a high sensitive photodiode, a low
noise amplifier, a 16-bit A/D converter and supports an • O-TrimTM technology adoption: ALS output tolerance
easy to use I2C bus communication interface and additional ≤ 10 %
interrupt feature. • 16-bit dynamic range for ambient light detection from
The ambient light result is as digital value available. 0 lx to about 120 klx with resolution down to 0.0036 lx/ct,
supports low transmittance (dark) lens design
APPLICATIONS • 100 Hz and 120 Hz flicker noise rejection
• Ambient light sensor for mobile devices (e.g. smart • Excellent temperature compensation
phones, touch phones, PDA, GPS) for backlight dimming • High dynamic detection resolution
• Ambient light sensor for industrial on- / off-lighting • Software shutdown mode control
operation
• Optical switch for consumer, computing, and industrial
devices and displays

2. I2C Interface
The VEML6030 contains actual six 16 bit command codes for operation control, parameter setup, and result buffering. All
registers are accessible via I2C communication. Figure 7 shows the basic I2C communication with VEML6030.
The built in I2C interface is compatible with I2C modes “standard” and “fast”: 10 kHz to 400 kHz.
I2C H-level range = 1.3 V to 3.6 V.
Please refer to the I2C specification from NXP for details.

Device Address With ADDR pin plugged to ground = low, the slave address
The VEML6030 has two fix slave addresses for the host (7 bit) is set to 0010000 = 0x10. According 8 bit the bus
programming and accessing selection. address is then 0010 0000 = 20h for write and 0010 0001 =
21h for read.
With ADDR pin plugged to power supply = high = VDD, the
predefined 7 bit I2C bus address is set to 1001000 = 0x48.
The least significant bit (LSB) defines read or write mode.
Accordingly the bus address is set to 1001 0000 = 90h for
write and 1001 0001 = 91h for read.

Register Addresses Auto-Memorization
VEML6030 has actual six user accessible 16 bit command VEML6030 can memorize the last ambient data before
codes. shutdown and keep this data before waking up.
The addresses are 00h to 06h (03h not defined / reserved). When VEML6030 is in shutdown mode, the host can freely
read this data via read command directly.
When VEML6030 wakes up, the data will be refreshed by
new detection.
