IS31FL3761 - Lumissil

IS31FL3761 33x12 DOTS MATRIX LED DRIVER

The IS31FL3761 is a general purpose 33 × n (n=12~1) LED Matrix programmed via 1MHz I2C or 12MHz SPI compatible interface. Each LED can be dimmed individually with 12-bit PWM data, and each color sink can have 8-bit DC scaling data which allows 4096 steps of linear PWM dimming and each color sink has 64 steps of DC current adjustable level. The output current.
