The UFS BGA 254 package, designed for high-performance mobile storage, often combines UFS and LPDDR RAM in mid-to-high-end devices, adhering to JEDEC UFS 2.1, 2.2, or 3.1 specifications. These chips operate via a full-duplex differential-signaling interface (M-PHY) with 2-lane operation, typical power requirements of VCC 2.7V–3.6V, and VCCQ2 1.7V–1.95V.
