IS32FL3746B Overview
The IS32FL3746B is a general purpose 18×n (n=1~4) LED Matrix programmed via 12MHz SPI interface. Each LED can be dimmed individually with 8-bit PWM data and 8-bit DC scaling data which allowing 256 steps of linear PWM dimming and 256 steps of DC current adjustable level. Additionally each LED open state can be detected, IS32FL3746B store the open information in OpenRegisters.
