How to Read a UFS BGA 254 Datasheet: Step-by-Step
If you have a vendor-specific datasheet (e.g., "Samsung KLUFG8RHDA-B0D1"), follow this workflow: Here is the complete feature set for a
UFS Features
- Storage Capacities: Available in various capacities, ranging from 32GB to 512GB or more, to suit different application needs.
- Interface: UFS uses a high-speed serial interface for data transfer, supporting speeds much higher than older interfaces like eMMC.
Electrical and interface specifications
- Supply voltages: typical VCC/VCCQ values defined per device (e.g., core and I/O rails such as 1.2 V/1.8 V/3.3 V variants depending on device family).
- I/O signaling: M-PHY physical layer with UniPro protocol stack; differential lanes for high-speed data.
- Signal integrity: termination, impedance control, and layout guidance in datasheet (trace length matching, controlled impedance).
- Power consumption: idle, active read/write, deep-sleep states — exact currents vary by device and capacity.

Typical Ball Assignment Groups:
| Ball Group | Pin Count | Description | |------------|-----------|-------------| | VCC (Main Supply) | ~20-30 balls (distributed) | 2.5V or 3.3V – core and NAND supply. Requires low-ESR decoupling caps. | | VCCQ (Controller I/O) | ~12-18 balls | 1.2V or 1.8V – interface logic and reference. | | VCCQ2 (Optional) | ~6-10 balls | 1.8V – for high-speed M-PHY. | | VSS (Ground) | ~60-80 balls | Multiple ground balls to reduce loop inductance. Critical for signal integrity. | | REF_CLK | 2 balls | Differential reference clock input (26MHz or 19.2MHz typical). | | UFS_D0_P / UFS_D0_N | 2 balls | Lane 0 differential pair (TX and RX shared). | | UFS_D1_P / UFS_D1_N | 2 balls | Lane 1 differential pair (optional for dual-lane mode). | | RST_N | 1 ball | Active-low hardware reset. Must be pulled high externally. | | CMD (Boot LUN) | 1 ball | Boot-specific control (varies by vendor). | | NC / RFU | ~40-60 balls | No Connect or Reserved for Future Use. Do not route to these. |
