eMMC utilizes a 1-bit, 4-bit, or 8-bit parallel data bus (DAT0–DAT7) along with a CMD (Command) line. UFS completely removes the parallel data bus in favor of dedicated, high-speed uni-directional differential serial lanes (Rx/Tx).
For a complete, vendor‑agnostic pinout table, the community‑maintained “UFS 3.1 BGA153 universal handbook” provides a full JEDEC‑equivalent ball assignment. This document is based on JESD220E and is the design baseline for all major UFS 3.1 vendors.
Below is a comprehensive technical breakdown of the UFS 3.1 pinout configuration, signal descriptions, and hardware implementation requirements. 1. UFS 3.1 Form Factors and BGA Configurations
Understanding the UFS 3.1 pinout is essential for modern hardware engineers working on performance-driven mobile and automotive systems. By strictly following the signal definitions—specifically the differential data lanes and robust power supply layout—designers can ensure reliable, high-speed data storage performance.
Here is the UFS 3.1 pinout:

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:
Reset (often required for stable detection on newer chips).
on the TX line to ground to enable communication with certain flasher boxes. ball-by-ball map ufs 3.1 pinout
If the phone cannot boot or detect storage, issues may arise from broken solder balls, improper power delivery ( VCCQcap V cap C cap C cap Q ), or a faulty
The chip is placed into a specialized UFS hardware programmer socket (such as Medusa Pro II, EasyJtag Plus, or MiPi Tester). These hardware tools use the standardized UFS 3.1 pinout to establish a direct connection to the storage controller, bypassing a broken phone processor to dump the physical memory. 6. UFS 3.1 vs. eMMC Pinout: Key Structural Differences
UFS 3.1 uses a split-rail power architecture to balance high-speed digital performance with ultra-low standby power consumption.
Multiple RPMB (Replay Protected Memory Block) regions. 2. UFS 3.1 Pinout Overview (BGA 153/100) eMMC utilizes a 1-bit, 4-bit, or 8-bit parallel
For hardware engineers, PCB designers, and data recovery technicians, understanding the is not just a theoretical exercise; it is a practical necessity. Whether you are designing a next-generation device, troubleshooting a dead phone, or attempting direct memory access for forensic analysis, the 153-ball BGA (Ball Grid Array) pinout is your roadmap.
Power supply for the high-speed MIPI M-PHY interface blocks. Typically operates at 1.2V . C. Clock and Control Signals
Universal Flash Storage (UFS) 3.1 is the standard for high-performance storage in modern smartphones, tablets, and embedded systems. Offering significantly faster read/write speeds, lower power consumption, and improved efficiency compared to older eMMC or earlier UFS versions, UFS 3.1 relies on a precise, serialized interface to deliver its capabilities.
