Spmi Online

Unlike I²C (which is general-purpose) or SMBus (which focuses on low-power system management), SPMI is optimized for with hardware-based command sequencing, interrupt handling, and sleep/wake transitions.

1. Overview SPMI (System Power Management Interface) is a high-speed, two-wire, bidirectional serial bus defined by the MIPI (Mobile Industry Processor Interface) Alliance. It is specifically designed to connect a processor (application processor, modem, or baseband) to one or more Power Management Integrated Circuits (PMICs) and other peripheral devices. Unlike I²C (which is general-purpose) or SMBus (which
