Lumissil IS32FL3202

The IS32FL3202 is a three-channel smart LED controller. Each channel supports 6-bit current adjustment for color setting and 16-bit PWM for smooth LED dimming control. To minimize EMI, the IS32FL3202 supports spread spectrum on the PWM clock generator. It supports Location Address Assignment for addressing hundreds of RGB LEDs without the need for address pins. The maximum output current of each LED channel is 63mA. The IS32FL3202 incorporates a state machine core that enables low-latency communication with any microcontroller over a CAN bus interface, speeding up the transmission of instructions for individual LED brightness and color control. This integrated state machine also measures the RGB LED temperature and employs a built-in temperature compensation algorithm to ensure consistent luminance across a wide temperature range. The temperature compensated PWM data is stored in 16-bit registers. All the IS32FL3202 registers can be accessed and updated via the fast CAN Bus.
