Isolated from RX lanes by VSS tracks to prevent loopback interference.
A multi-chip package (MCP) footprint that frequently integrates both UFS 3.1 storage and LPDDR RAM into a single IC to save motherboard real estate. 2. UFS 3.1 Pinout Signal Categorization
Note: For ISP, power is often supplied via the device's USB port (battery connected) rather than external VCC wires to avoid current supply issues. UFS | eStorage | Samsung Semiconductor Global
(Note: Some early UFS implementations used a VCCQ rail for the controller and VCCQ2 for the PHY, but modern UFS 3.1 BGA packages generally consolidate these into the standard VCC and VCCQ2 configuration.) ufs 3.1 pinout
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.
Because UFS 3.1 supports dual-lane data transmission (Gear 4), it features two dedicated upstream channels and two dedicated downstream channels. High-Speed Differential Data Lanes

However, understanding UFS 3.1 requires more than just looking at speed benchmarks; it requires understanding the physical layer. Unlike the parallel interface of eMMC, UFS utilizes a serial differential interface. This article provides a deep dive into the , explaining the signal paths, voltage rails, and the physical form factors that define modern mobile storage.
