IS31FL3216
16 CHANNELS LED DRIVER
January 2012
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 à 4mm). It
operates from 2.7V to 5.5V over the temperature range
of -40°C to +85°C.
