IS31FL3730

IS31FL3730 AUDIO MODULATED MATRIX LED DRIVER May 2018 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.
