Mipi Spmi Specification Pdf Site

Do you currently use SPMI in your designs, or are you still relying on older PMBus/I2C solutions? Let’s discuss in the comments.

A simple two-wire CMOS-based interface consisting of: SDATA: Bi-directional serial data signal. SCLK: Unidirectional serial clock signal. mipi spmi specification pdf

MIPI SPMI (System Power Management Interface) is a low-pin-count, high-efficiency serial bus standard designed for communication between application processors and power-management integrated circuits (PMICs). It reduces board complexity and power consumption by enabling scalable, point-to-point or shared bus topologies for control and telemetry of power rails, regulators, and sensors. Do you currently use SPMI in your designs,

No, unless you are a MIPI member. Individual purchase costs several hundred dollars. However, the MIPI Alliance offers a "Register to Download" option for some public specifications, but SPMI typically requires a paid license. SCLK: Unidirectional serial clock signal
