I2C Controller

I2C Controller

The I²C Controller IP Core is a silicon-proven, highly reliable solution designed for robust synchronous serial communication in advanced SoC and FPGA platforms. Fully compliant with the latest I²C specifications, this controller enables seamless, industry-standard connectivity for a broad ecosystem of I²C-compatible devices—ranging from sensors and memory modules to power management ICs and peripheral controllers. This IP core supports both multi-master and multi-slave operation, making it ideal for complex system topologies where flexibility and reliability are paramount. Its architecture is highly configurable, allowing design teams to tailor features such as FIFO depth, clock prescalers, interrupt management, and address modes (7-bit/10-bit) to specific application requirements.With support for APB and AXI host interfaces, the core integrates easily into both legacy and modern SoC buses, ensuring rapid design closure and minimal integration effort. Advanced I²C protocol features—including clock stretching, multi-master arbitration, programmable SCL/SDA timing, and glitch filtering—are natively supported to maximize interoperability and data integrity, even in electrically noisy or demanding environments. The core has been validated in silicon, guaranteeing proven performance, interoperability, and long-term reliability. Built-in error detection,comprehensive status reporting, and integrated interrupt controller further streamline embedded software development and system debug.
