SmartDV’s PMBus Master IP is a silicon-proven, fully featured power management bus solution purpose-built for SoC designs requiring reliable, standards-compliant communication with power management ICs, voltage regulators, and other PMBus-compatible devices across server, data center, automotive, and high-performance embedded applications. Fully compliant with PMBus v1.4.1 Part II, SMBus v3.3.1, and I2C v6.0, it delivers complete master-side I2C, SMBus, and PMBus functionality across all speed modes from Standard-mode at 100 kbit/s through Ultra Fast-mode at 5 Mbit/s.
Designed to address the full breadth of modern power management bus requirements, the IP supports the complete PMBus command set including Zone Write and Read, Extended Command Protocol, Address Resolution Protocol, and Device Fault Management, alongside comprehensive packet error checking, alert and suspend handling, and master arbitration and clock synchronization. Its HCI and non-HCI interface options give SoC teams the flexibility to deploy a standards-compliant PMBus master across both OS-managed and bare-metal power management architectures.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its parameterized architecture, dual HCI and non-HCI interface options, and clean host interface enable fast integration and confident design bring-up across a wide range of process nodes and power management applications.
