IS31FL3719 Overview
FEATURES The IS31FL3719 is a general purpose 15×9 or 16×8 LED Matrix driver programmable via 1MHz I2C patible interface. All LED can be turned on and off individually, and 9×7 or 8×8 of the matrix’s LED can be dimmed individually with 8-bit PWM data. All LED has a global 7-bit current control (GCC) data which allowing 128 steps of linear DC current adjustable levels.
