Ufs 3.1 - Pinout

The Universal Flash Storage (UFS) standard has rapidly become the backbone of high-performance mobile computing. From flagship smartphones like the Samsung Galaxy S23 to automotive infotainment systems and professional drones, UFS 3.1 offers sequential read speeds exceeding 2,100 MB/s—dwarfing the capabilities of eMMC.

Whether you are repairing a bricked smartphone or designing a high-end ADAS system, the 153 balls of the UFS 3.1 package hold the keys to high-speed, reliable storage. Treat them with the respect that 11.6 Gbps demands. ufs 3.1 pinout

UFS 3.1 typically utilizes a (153-ball) package with an 11.5mm x 13.0mm footprint. Unlike the parallel interface of eMMC, UFS uses a serial differential interface (MIPI M-PHY) to achieve significantly higher speeds—over 1,500 MB/s for UFS 3.1. ⚡ Critical Signal Groups The Universal Flash Storage (UFS) standard has rapidly

Many balls on the 153 BGA are or R.F.U. (Reserved for Future Use) . For production designs, these must be left floating or connected to VSS as per the specific manufacturer's datasheet.

: Many central balls (e.g., row F–J) are NC (No Connect) . Do not ground them – they may be test points or unused.

⚠️ Pinouts vary by manufacturer! A Samsung chip may not map 1:1 with a Micron chip on the exact same footprint. Always verify the datasheet for the specific Part Number.
