IS31FL3751 - Lumissil

IS31FL3751 9x8 MATRIX LED DRIVER

The IS31FL3751 is a general purpose 9×8 LED Matrix programmed via 1MHz I2C compatible interface. Each LED can be dimmed individually with 12-bit PWM data and each LED can be dimmed with 4-bit DC scaling (Color Calibration) data which allowing 4096 steps of linear PWM dimming and 16 steps of DC current level adjustment. Additionally each LED open and short st.
