Ufs Bga 254 Datasheet

Designing with a current UFS 3.1 BGA 254 socket or footprint can be forward-compatible if you keep power delivery over-provisioned and route all unused balls as "NC" with test points.

: Typically a 11.5mm x 13.0mm or 12.0mm x 15.0mm package with 254 solder balls. Ufs Bga 254 Datasheet

Crucially, the datasheet details the (e.g., Gear 1, 2, 3, 4, up to 5.8 Gbps per lane). Where an eMMC datasheet speaks of a single 8-bit parallel bus with setup/hold times, the UFS BGA 254 datasheet speaks of differential line pairs (RXN/RXP) and unidirectional lanes . This is a physical acknowledgment that storage is no longer a peripheral; it is a peer on the high-speed interconnect. The layout engineer must treat these traces as RF transmission lines, complete with impedance control (typically 50Ω differential) and length matching within 0.5mm – a stark contrast to the forgiving parallel bus of eMMC.

The "254" refers to the number of solder balls on the underside of the package. The grid is typically a : (Input) and (Output) differential pairs. Control : (Reference Clock), (Hardware Reset). DRAM Interface : Includes dedicated balls for DQcap D cap Q CAcap C cap A (Command/Address), and CKcap C cap K (Clock) for the LPDDR section of the MCP. 4.
