Introducing the New IP Core in Silesia Devices’ Portfolio

MIPI I3C Basic Secondary Controller: Elevating Connectivity Standards


As the demand for seamless connectivity and efficient communication in the IoT ecosystem intensifies, the I3C protocol emerges as an unequivocal frontrunner among the protocols currently available in the market. Offering a compelling synthesis of speed, device connectivity, low-power efficiency, and reduced complexity and intricacies in the hardware setup, the I3C positions itself as the go-to solution for engineers seeking a protocol addressing the limitations of existing alternatives.

That’s why one of our engineering teams spent the last few months creating MIPI I3C Basic Secondary Controller IP Core. This IP core not only implements the most popular subset of the I3C specification, but does it with the maximum possible overhead reduction for the host processor, performing most of the protocol layer operations autonomously. Configurability is at the core of its design, facilitated by Verilog definitions, ensuring adaptability to diverse use cases.

Key attributes that set apart our product from existing IP’s:

1. AHB Manager Bridge:
A distinctive feature allowing the IP Core to act as an AHB Manager Bridge, enabling autonomous data transmission and management. This autonomy streamlines operations, directing traffic through the AHB with minimal host intervention—a unique functionality not standard in I3C.

2. Low Power Feature:
Introduces a low-power mechanism from the AHB perspective. The clock need not operate unless AHB communication is imminent, signaling clock requirements only when data is present in the FIFO—an additional, power-efficient feature.

3. Secondary Controller Capability:
Offers the capability to function as a secondary controller, providing flexibility in managing transmissions as a temporary controller.

4. CCC Command Support:
Implements support for Common Command Codes (CCC), a feature absent in I2C, enhancing command-level functionalities.

5. Legacy Mode Compatibility:
Ensures compatibility with legacy mode I2C in private transmissions, widening the scope of interoperability.

6. Defined FIFOs:
Provides defined FIFOs, alleviating the need for byte-by-byte data handling, enhancing efficiency for the end user.


Technical Insights

The I3C-SC core, compliant with the MIPI I3C BasicSM specification, serves as a versatile secondary controller supporting Single Data Rate (SDR) mode. It seamlessly communicates with legacy I2C devices and can be configured for I3C or I2C bus operation.
