Overview

The PCA9685PW/Q900,118 is an I²C-bus controlled 16-channel LED controller optimized forRed/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has itsown 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operatesat a programmable frequency from a typical of 24 Hz to 1526 Hz with a duty cycle that isadjustable from 0 % to 100 % to allow the LED to be set to a specific brightness value.All outputs are set to the same PWM frequency.

The Software Reset (SWRST) General Call allows the master to perform a reset of thePCA9685PW/Q900,118 through the I²C-bus, identical to the Power-On Reset (POR) that initializes theregisters to their default state causing the outputs to be set LOW. This allows an easy andquick way to reconfigure all device registers to the same condition via software.
