IS31FL3766 - Lumissil

IS31FL3766 18??6 DOTS MATRIX LED DRIVER

The IS31FL3766 is a general purpose 18 × 6 (n=1~6) LED Matrix programmed via 1MHz I2C compatible interface. Each LED can be dimmed individually with 12-bit/8+4-bit/8-bit/6+2-bit PWM data and each color sink can have 8-bit DC scaling data which allowing 256 steps of linear PWM dimming and each color sink has 256 steps of DC current adjustable level and precis.
