GENERAL DESCRIPTION
The IS31FL3216 is a fun light LED controller with an audio modulation mode. It can store data of 8 frames with internal RAM to play small animations automatically.
IS31FL3216 can sample the input signal to modulate the intensity of LEDs, or control 8 frames playing by internal ADC block.
The LED current of each channel can be set in 256 steps by adjusting the PWM duty cycle through an I2C interface. 8 channels can be used as GPIO ports. IS31FL3216 is available in QFN-28 (4mm × 4mm). It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
