MIPI System Power Management Interface (SPMI)

The is a standardized high-speed, two-wire serial bus specification developed by the MIPI Alliance . It provides a unified hardware interface for communication between a system-on-chip (SoC) application processor and multiple peripheral components, specifically Power Management Integrated Circuits (PMICs) .

Two-Wire Interface:

Uses one bidirectional data line (SDATA) and one clock line (SCLK). mipi spmi specification pdf

The official specification PDF includes an appendix with annotated transaction logs. Additionally, the MIPI Alliance publishes a "SPMI Primer" whitepaper (often free) that summarizes the PDF’s content. MIPI System Power Management Interface (SPMI) The is

1.2 What is MIPI SPMI?

The MIPI SPMI protocol defines the communication mechanism between power management components. The protocol includes: Overview of MIPI SPMI

  1. Overview of MIPI SPMI

    • MIPI SPMI official overview page (public)
    • Linux kernel SPMI subsystem documentation
    • Qualcomm PMIC hardware manuals (often reference SPMI timing but not full spec)
    • MIPI SPMI Protocol Decoder (Saleae, Teledyne LeCroy): These logic analyzers include SPMI decoders that parse commands directly from the bus.
    • MIPI DisCo for SPMI: A specification addendum for device tree configuration (Linux/Android).
    • PMIC Documentation (Qualcomm, Dialog, TI): Each PMIC datasheet references specific SPMI command sequences. Read these alongside the main SPMI PDF.
