AUDIO MODULATED MATRIX LED DRIVER
December 2011
GENERAL DESCRIPTION
IS31FL3730 is a LED matrix driver which features an
audio modulation display mode and a general LED dot
matrix display mode. The default configuration of
IS31FL3730 is to drive a single 8×8 LED matrix.
However, IS31FL3730 may be configured to drive
either one or two 8×8, 7×9, 6×10, or 5×11 dot matrix
display(s). The intensity of any matrix picture can be
modulated by an audio signal.
In matrix display mode, the rows and columns of the
matrix are internally scanned, requiring only one time
programming of the individual LED on or off state, thus
eliminating the need for real time system resource
utilization to perform the row and column scanning
function.
In the general purpose mode, the ON or OFF condition
of each individual LED in the display matrix is
programmed via an I2C interface.
IS31FL3730 is available in QFN-24 (4mm × 4mm). It
operates from 2.7V to 5.5V over the temperature range
of -40°C to +85°C.

Note 1: Due to the row and column scanning sequence, the average current of an individual LED in the display is IOUT/8 when configured to
drive a single matrix. When configured to drive two matrices, the average current of an individual LED in the display is IOUT/16.
Note 2: All row drivers are on.
Note 3: Guaranteed by design.
Note 4: Cb = total capacitance of one bus line in pF. ISINK 6mA. tR and tF measured between 0.3 × VCC and 0.7 × VCC.
