IS31FL3732 AUDIO MODULATED MATRIX LED DRIVER GENERAL DESCRIPTION The IS31FL3732 is a compact LED driver for 144 single LEDs.
The device can be programmed via an I2C compatible interface.
The IS31FL3732 offers two blocks each driving 72 LEDs with 1/9 cycle rate.
The required lines to drive all 144 LEDs are reduced to 18 by using the cross-plexing feature optimizing space on the PCB.
Additionally each of the 144 LEDs can be dimmed individually with 8-bit allowing 256 steps of linear dimming.
To reduce CPU usage up to 8 frames can be stored with individual time delays between frames to play small animations automatically.
LED frames can be modulated with audio signal.
IS31FL3732 is available in...
