UFS 3.1 is designed for a wide range of applications, including:
UFS 3.1 devices require stable, clean power rails to prevent data corruption during high-speed reads and writes:
The specialized pinout of UFS 3.1 supports several advanced power and performance features introduced in the 3.1 standard:
The UFS 3.1 pinout is defined around . Successful interfacing requires strict power sequencing, clean differential routing, and correct reference clock. Always obtain the chip's dimensioned ball map (from datasheet or board schematic) before soldering or probing. ufs 3.1 pinout
Different manufacturers (Samsung, Kioxia, SK Hynix) may rename these. Common alternatives:
The UFS host pinout consists of the following pins:
While the contains the complete electrical and protocol definition, it does not include a standardized ballmap as part of the standard. Instead, each manufacturer publishes its own datasheet that references the JEDEC electrical requirements but provides the specific ball assignment for its package. Main Power Supply for the memory controller and NAND flash
Main Power Supply for the memory controller and NAND flash. VCCQ / VCCQ2: Power Supply for the interface and M-PHY.
The positive and negative traces of each differential pair must be perfectly length-matched to avoid phase skew, which corrupts the high-speed serial data stream.
UFS 3.1 leverages the MIPI M-PHY physical layer and MIPI UniPro link layer to achieve high bandwidth. The pinout represents the physical layout of the 153 solder balls on the underside of the NAND flash package. B5) for a specific BGA package?
If you are designing a PCB with UFS 3.1, I can provide more details on routing guidelines or help you identify specific power requirements based on a particular manufacturer's data sheet. Datasheet - Arasan Chip Systems
Do you need the (e.g., A3, B5) for a specific BGA package?
