No. SPMI is for power management devices. Use I2C for sensors, audio codecs, and touch controllers.
Exact voltage thresholds, pull-up/pull-down resistor values, and capacitive loading limits for the SDA and SCL lines. mipi spmi specification pdf
When reviewing the MIPI SPMI specification PDF, you will find highly detailed timing, electrical, and protocol parameters. Below is a summary of the standard performance metrics: Specification 2-wire (SCLK, SDATA), multi-master, multi-slave Maximum Clock Speed Up to 26 MHz Voltage Rails Typically 1.2V or 1.8V I/O configurations Arbitration Priority-based, built-in bit-level arbitration Data Throughput Optimized for small, frequent control packets 4. Protocol and Frame Structure
Here's a concise post you can use to share information and a link about the MIPI SPMI specification PDF. Use an oscilloscope with an
The (System Power Management Interface) is a standardized, high-speed, low-latency, two-wire serial interface designed for communication between a processor (typically the power controller in an SoC) and peripheral components, most notably Power Management Integrated Circuits (PMICs).
A standard SPMI transaction consists of the following phases: Use I2C for sensors, audio codecs, and touch controllers
| Feature | MIPI SPMI | I2C | SMBus | PMBus | | :--- | :--- | :--- | :--- | :--- | | | 2 | 2 | 2 | 4 (with alert) | | Multi-master | Yes (collision detect) | No (requires arbitration) | No | No | | Target Devices | Up to 16 PMICs | Up to 128 | Up to 128 | Up to 100 | | Speed | Up to 26 MHz | Up to 5 MHz (fast mode plus) | Up to 1 MHz | Up to 1 MHz | | Power Optimized | Yes (sleep/dynamic clock) | No | Partial | No | | Primary Use Case | CPU to PMIC | Sensors, EEPROM | Battery management | Power supplies |
To implement or verify a system using MIPI SPMI, engineers need access to the official, detailed specification document. The MIPI SPMI specification document provides:
Every device on the bus is assigned a unique priority level. Master devices generally hold higher priority than slave devices.
