Art-Net Controller – IS3740

Revolutionize Lighting Control with the IS3740 ArtNet Controller Chip

The ArtNet Controller Chip IS3740 is the ultimate solution for manufacturers and developers seeking to integrate standardized professional lighting control into their products with minimal effort. ArtNet is the most widely adopted protocol for transmitting DMX512 data over Ethernet networks. Implementing this complex networking stack—including the underlying TCP/IP, UDP, and the specific ArtNet application layer—can consume significant development resources. The IS3740 eliminates this struggle by embedding both the full Ethernet stack and the ArtNet protocol into one powerful chip.

Immediate Time-to-Market Advantage

The traditional approach to ArtNet integration requires specialized knowledge in networking, socket programming, and real-time data handling. This often results in long, costly development cycles. The IS3740 abstracts away the entire network complexity. Your host microcontroller’s job is reduced to sending simple DMX data frames via the Serial Peripheral Interface (SPI) bus.

This hardware acceleration offers several critical benefits:

• Drastic Time Savings: Skip months of coding and debugging network and protocol layers.

• Simplified Hardware: Utilize smaller, less powerful (and thus cheaper) microcontrollers, as the IS3740 handles the heavy processing load.

• Guaranteed Interoperability: The chip’s pre-verified ArtNet implementation ensures seamless communication with all professional lighting consoles and software.

Straightforward Data Flow via SPI

The operational simplicity is a core feature of the ArtNet Controller Chip. Data transfer is highly intuitive:

1. Your host MCU gathers or generates DMX control data.

2. The MCU sends this raw data to the IS3740 over the high-speed SPI bus.

3. The IS3740 automatically formats the data into the correct ArtNet packets, manages the Ethernet communication, and sends the lighting information across the network.

This direct, SPI-to-ArtNet data path ensures extremely low latency, which is essential for professional lighting applications, ranging from stage lighting and architectural installations to kinetic art displays.
