Introduction

The MIPI System Power Management Interface (MIPI SPMI℠) is a standardized, high-speed, two-wire serial interface designed to facilitate efficient communication between a System-on-Chip (SoC) and power management integrated circuits (PMICs). It was developed by the MIPI Alliance to replace legacy point-to-point interfaces, significantly reducing pin count and board complexity in mobile and portable devices. mipi spmi specification pdf

3. Public summaries: MIPI offers overview documents (not full spec) on their website.
4. Chipset vendor documentation: Qualcomm, MediaTek, etc., often include SPMI implementation details in their technical reference manuals (TRMs).

Typical Use Case: Application processor (master) sends a command to the PMIC (slave) to lower CPU voltage during idle — all over SPMI. MIPI Alliance Member: Download directly from https://www

. However, technical summaries and application notes can be found from providers like Prodigy Technovations of the different SPMI versions or a of the multi-master bus topology? MIPI System Power Management Typical Use Case: Application processor (master) sends a

The interface supports a multi-master, multi-slave configuration, allowing up to 4 masters and 16 slaves on a single bus. Masters are typically integrated power controllers within the SoC, while slaves are voltage regulation systems within PMICs. Key Technical Specifications
