MIPI System Power Management Interface (MIPI SPMIâ„ ) is a critical hardware standard developed by the MIPI Alliance
PMICs, voltage regulators, or sensor hubs. The architecture supports up to 16 logical slave devices.
By providing a unified standard for components from different manufacturers, MIPI SPMI offers several industry advantages: Space Savings 🔗 The official PDF is available for download
If you are a hardware designer, firmware engineer, or technical architect, searching for the is likely your first step toward understanding how to reduce pin counts, lower power consumption, and streamline communication between processors and power management ICs (PMICs).
The current release is v2.0 , which was finalized in 2012. While the specification itself is restricted to MIPI Alliance members, its core features are widely implemented in commercial IP cores.

The protocol natively supports advanced system topologies, allowing up to 4 master devices and up to 16 slave devices on a single shared bus. This multi-master capability is crucial for modern devices where a primary application processor, a modem, and a dedicated sensor hub might all need to independently request power state changes from the same central PMIC. High-Speed Performance
defines a high-speed, low-latency, two-wire serial interface that connects a System-on-Chip (SoC) processor to one or more Power Management Integrated Circuits (PMICs). Its primary role is to accurately monitor and dynamically control supply voltages in real time based on the processor's current workload. In technical terms: The Master: Resides within the SoC's integrated Power Controller (PC). The Slave: Resides within the PMIC's voltage regulation systems. Key Technical Features
