I2C Controller for Addressable LED - IS3750

The IS3750 is a One-Wire Addressable LED controller chip. Your microcontroller writes the LED data to the IS3750 internal memory map via I2C, while the chip continuously renders and streams this data, keeping the LEDs updated. Since all the complex tasks of data rendering and streaming are handled by the IS3750, your microcontroller can send the data at a relaxed pace—slowly or in paused partial updates—without any issues, allowing the IS3750 to keep the LEDs perfectly updated..

The IS3750 frees your microcontroller from the strict timing requirements of controlling the One-Wire protocol, thereby reducing the use of timers, flash memory, and RAM. It also eliminates the need for a dedicated pin, as it operates over a shared bus (I2C).

The aim of the IS3750 is to save engineering time and costs associated with implementing and testing the Modbus RTU communication protocol, providing a reliable solution that reduces the time-to-market (TTM) of your product.

The device operates at 3.3V, and its I/O pins are 5V tolerant, allowing the use of either 3.3V or 5V microcontrollers. It is available in two temperature ranges: Industrial (-40ºC to +85ºC) and Extended (-40ºC to +125ºC).
