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
While the physical package layout (BGA) varies by manufacturer (Samsung, Western Digital, SK Hynix, Kioxia), the logical interface defined by the JEDEC standard (JESD220E) remains consistent. ufs 3.1 pinout
UFS 3.1 utilizes a differential serial interface (M-PHY) with up to two lanes for data transfer. Mouser Electronics Data Lanes (Differential Pairs): DIN_t / DIN_c: Input data lanes (Host to Device). DOUT_t / DOUT_c: Output data lanes (Device to Host). Power Supplies: VCC (2.7V – 3.6V): Main power for the NAND flash media. VCCQ (1.14V – 1.26V): Power for the UFS controller and I/O interface. VCCQ2 (1.7V – 1.95V): Power Supplies: VCC (2
