IS31FL3761 Overview
The IS31FL3761 is a general purpose 33 × n (n=12~1) LED Matrix programmed via 1MHz I2C or 12MHz SPI patible 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 of each channel is designed to be 30mA, which can be adjusted...
