Ufs 3.1 Pinout

⚠️ : UFS 3.1 uses M-PHY 4.1 (Gear 4) and UniPro 1.8 . While the pinout is physically compatible with UFS 2.x, high-speed signals (Rx/Tx) require stricter PCB layout. Always verify with the specific component datasheet (e.g., Samsung, Kioxia, Micron, SK Hynix).

🔹 Unlike the parallel bus of eMMC, UFS relies on high-speed differential signaling.

eMMC uses a continuous operating clock signal (CLK). UFS uses a reference clock ( REF_CLK ) to internally lock phase-locked loops (PLLs) for burst-mode transmission, conserving power.
