Ufs 3.1 Pinout

standard (JESD220E) typically uses a 153-ball BGA (Ball Grid Array) package, similar to previous UFS generations like 2.1 and 3.0, but with updated electrical specifications for higher speeds. Key Signals and Power Rails

Unlike UFS 2.1, UFS 3.1 strictly requires the hardware reset signal to be implemented to properly initialize the device after power-on.

While exact coordinates can vary slightly by manufacturer (such as Samsung, SK Hynix, or Micron), the critical high-speed lines generally cluster together to minimize PCB trace lengths. Below is a conceptual view of how key functional pins are organized:

Because UFS 3.1 datasheets are under NDA for many manufacturers, your best public resources are:

While many UFS 2.1 devices also used BGA 153, the signaling and speed requirements for UFS 3.1 differ. UFS 3.1 operates at High-Speed Gear 4 ( ), requiring superior signal integrity compared to in older models. Voltage: UFS 3.1 often operates at lower VCCQcap V cap C cap C cap Q voltages to reduce power consumption.

Universal Flash Storage (UFS) 3.1 is a cornerstone technology in modern high-end smartphones, automotive infotainment systems, and embedded devices. Delivering sequential read speeds up to 2,100 MB/s, UFS 3.1 bridges the gap between mobile storage and desktop-class NVMe SSDs.
