CM32181
Low Power, High Sensitivity
I2C Ambient Light Sensor
Rev: 1.1 Revised 11th-June-2013
Description
Features
CM32181 is an advanced ambient light sensor with
I2C protocol interface and designed by the CMOS
process. It is easily operated via a simple I2C
command. The active interruption feature within the
threshold windows setting offers the benefit of
eliminating loading of the controller monitor.
CM32181 incorporates a photodiode, amplifiers and
analog circuits into a single chip. The best spectral
sensitivity is used to closely capture real human eye
responses. CM32181 has excellent temperature
compensation. Its robust refresh rate setting does not
need an external RC low pass filter. Software
shutdown mode is provided which reduces power
consumption to be less than 0.5μA. CM32181’s
operating voltage ranges from 2.5V to 3.6V and
consumes only 1uA. The maximum detective light
strength is over 167K Lux.
Block Diagram
Filtron™ technology adoption :
excellent responsivity : close to real human eye
responses
