概觀

IS31FL3728 is a general purpose 8×8 LED matrix driver which features an audio frequency equalizer (EQ) mode or a general LED dot matrix display mode. The general LED matrix display defaults to an 8×8 configuration, however, it can be configured for a 5×11, 6×10, 7×9 dot matrix display. The m atrix picture brightness can be modulated by audio. In either the audio EQ mode or matrix display mode, the array is internally scanned, and requires only one-time programming, thus eliminating the need for real time system resource utilization. It programs the LED array through I2C interface. In the general purpose display mode, each dot of the LED array is independently programmed on or off over time. In the audio EQ mode, the X axis (column) represents the frequency bands while the Y axis (row) represents the strength of the input audio signal in each band. The number of LEDs lit in a column is proportional to the strength of the audio signal in the corresponding band in a thermometer-coded manner. IS31FL3728 is available in 24-pin QFN (4mm × 4mm). It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C (IS31FL3728-QFLS2-TR), -40°C to +105°C (IS31FL3728-QFLS3-TR).
