IS31FL3739 Overview
The IS31FL3739 is a general purpose 8×8 or 7×9 matrix LED driver programmed via a 1MHz I2C bus patible interface. Each LED can be dimmed individually with 8-bit PWM data, and each CSx has 8-bit DC current scaling for color calibration. The bination enables 256 steps of linear PWM dimming for each dot and 256 steps of DC current adjustment for each CSx.
