Power supply for the UFS controller logic. Typically 1.2V or 1.8V.
Up to 5.8 Gbps per lane (Total 11.6 Gbps for 2 lanes).
The UFS BGA 254 datasheet typically consists of the following sections:
: Up to 2 lanes for receive (RX) and 2 lanes for transmit (TX).
UFS, or Universal Flash Storage, is the high-speed flash storage standard that has largely replaced eMMC (embedded MultiMediaCard) in performance-oriented devices like flagship smartphones. BGA, or Ball Grid Array, is a surface-mount packaging technology that uses a grid of tiny solder balls to connect the chip to a printed circuit board (PCB). The number specifies the total count of these solder balls, defining the package's physical and electrical interface. This packaging is physically standardized, for instance, measuring approximately 11.5mm x 13mm with a ball pitch of 0.5mm . Ufs Bga 254 Datasheet
Utilizes the MIPI M-PHY physical layer and UniPro link layer.
The compact 11.5 × 13 mm footprint saves valuable PCB space. 4. Common Applications
: Many BGA 254 sockets are "2-in-1" designs, supporting both
Control lines and the reference clock (REF_CLK) are typically routed at 50 ohms single-ended impedance. Trace Length Matching Power supply for the UFS controller logic

UFS BGA 254 is a standardized high-performance memory package commonly used in modern smartphones (like Samsung and Xiaomi) and automotive electronics. It follows the JEDEC Universal Flash Storage (UFS)
If you can tell me the (e.g., Samsung, Micron, Western Digital) or the device you are repairing , I can help you find a more accurate, model-specific datasheet. Would you like a breakdown of the differences between UFS 2.1 and UFS 3.0 in this package?
The positive (_t) and negative (_c) traces of each differential pair must be tightly matched in length—ideally within ±0.1mm. Intra-pair skew can cause phase shifts that close the data "eye diagram," leading to bit errors. Additionally, Lane 0 and Lane 1 trace lengths must be closely matched to prevent inter-lane latency issues. Decoupling Capacitor Placement The UFS BGA 254 datasheet typically consists of
To get the most accurate, detailed technical specifications (such as power-on sequence, exact pin locations, and timing diagrams), it is highly recommended to consult the manufacturer-specific datasheet (e.g., Western Digital iNAND or Samsung UFS) available on Scribd or official manufacturer websites.
Traditional repair tools can’t talk to it. The pins are so small and numerous that a single shaky hand could short the entire board. The Secret: If the chip's part number has an 'M' after the 'K' (e.g., ), it’s an with built-in RAM. If it’s an 'L', it’s a standalone
Ignoring these details can lead to signal integrity issues, boot failures, or catastrophic field returns.
A typical UFS BGA 254 datasheet, such as those provided by manufacturers like Samsung or Micron, includes several vital sections:
