IS3750 General Description

The IS3750 handles Addressable LED signal generation autonomously, requiring no CPU intervention. It is capable of controlling up to 1200 LEDs, with a dedicated RAM of 3600 registers—one for each color of each LED.

Your microcontroller writes the LED data to the IS3750's internal memory map via I2C, and the IS3750 will render and stream the data.

Since the IS3750 handles all the time-critical tasks of data rendering and streaming, your microcontroller can send data without being constrained by the timing requirements of the addressable LED protocol. This allows for more flexible data transmission over I2C, enabling the IS3750 to keep the LEDs perfectly synchronized.

The usage of the IS3750 also reduces CPU interruptions, peripheral usage (such as timers), and both flash and RAM consumption. Additionally, it eliminates the need for dedicated pins, as it operates over a shared I2C bus.

The IS3750 saves engineering time and associated costs by handling the communication protocol, providing a reliable solution that reduces the time-to-market (TTM) for your product

IS3750 Main Advantages

  • LED Agnostic: compatible with any color sequence and color quantity: GRB, RGB, GRBW, etc.

  • Offloads your microcontroller’s processing load by independently handling the Addressable LED protocol.

  • Reduces firmware development time—no need to implement the protocol yourself.

  • Minimizes Flash and RAM footprint in your microcontroller.

  • The use of I2C eliminates the need for dedicated pins.

  • 3,600 bytes of RAM: drive 1200 3-color LEDs or 900 4-color LEDs

IS3750 Applications

  • Custom lighting

  • LED signaling

  • Color-coded process indicators

  • Architectural lighting

  • Status bars or meters

  • Interactive buttons or sliders with visual feedback
