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 Application CircuitFig. 12 - Application Circuit(x) = Pin NumberNotes 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.

10 Proposed value R2 should be >1 k , 10 k to 100 k . Proposed value for R3 and R4, k to k , 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.
