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.
FEATURES
2.7V to 5.5V supply
I2C interface, automatic address increment
function
Internal reset register
Programmable single or dual 8×8, 7×9, 6×10, or
5×11 LED matrix display mode
One-time programming, internal scan
Audio modulated display intensity with digitally
programmable input gain
Internal registers to digitally adjust display
intensity
Modulate LED brightness with 128 different items
in PWM
One address pin with 4 logic levels to allow four
I2C slave addresses
Over-temperature protection
QFN-24 (4mm × 4mm) package
APPLICATIONS
Mobile phones and other hand-held devices for
LED display
LED in home appliances
TYPICAL APPLICATION CIRCUIT
