According to technical specifications from Arasan Chip Systems and Kingston , the pinout is categorized into high-speed data lanes, power supply lines, and control signals.
UFS 3.1 | Universal Flash Storage | Samsung Semiconductor Global
Maintaining stable power is critical for UFS 3.1 performance, especially with features like "Write Booster". ufs 3.1 pinout
UFS 3.1 (Universal Flash Storage) is a high-speed, serial interface designed for mobile systems like smartphones and tablets. Unlike older parallel interfaces like eMMC, the utilizes Low Voltage Differential Signaling (LVDS) to achieve high-performance full-duplex operation, allowing the device to read and write simultaneously. UFS 3.1 Pin Configuration Overview
Differential data lanes for receiving data from the storage device to the host. Unlike older parallel interfaces like eMMC, the utilizes
Ground pins used for power return and signal shielding. Clock and Control Signals
UFS 3.1 relies on the MIPI M-PHY physical layer, which uses differential pairs for data transmission. Clock and Control Signals UFS 3
Differential data lanes for sending information from the host to the storage device.
Power supply for the controller and I/O interface, typically 1.14V to 1.26V (nominal 1.2V).
