Hardware reset pin (active low) used by the host controller to initialize or recover the storage device. Power Supply Rails
The 254-ball count provides enough I/O pins to handle the expanding interface of UFS (M-PHY lanes) while integrating massive storage controllers. It is the standard packaging for systems. A uMCP using the 254-BGA form factor frees up roughly 40% of the board space compared to discrete solutions, which is critical for fitting larger batteries into slim devices.
All RX and TX differential pairs must be routed with a target differential impedance of (or

The 254-ball matrix contains a high percentage of ground (VSS) and power (VDD) balls to provide shielding and stable voltage rails for high-speed data transmission. The primary signal groups listed in the datasheet include: High-Speed MIPI M-PHY Interface
A critical high-frequency reference clock input (typically ) used to synchronize the M-PHY PLLs.
UFS BGA-254 refers to a Universal Flash Storage (UFS) device packaged in a 254-ball ball-grid array (BGA) footprint. It’s a high-performance embedded flash storage solution commonly used in smartphones, tablets, IoT devices, and other compact systems that require fast sequential and random I/O with low power consumption. Hardware reset pin (active low) used by the
As a point of comparison, UFS BGA 254 is a more advanced and much faster standard compared to the older eMMC technology, thanks to its full-duplex, serial interface. A UFS 2.1 chip can achieve sequential read speeds of up to 850 MB/s, which is a major leap from the ~250 MB/s typical of eMMC 5.1.
: A high-speed SLC (Single-Level Cell) cache that significantly improves burst write speeds.
Ranging from 64GB, 128GB, 256GB, to 512GB and 1TB. Voltage: Optimized for low power, usually operating at 1.8V1.8 cap V VDDQcap V cap D cap D cap Q VCCcap V cap C cap C 3. UFS BGA 254 Pinout Analysis A uMCP using the 254-BGA form factor frees

In a mobile or industrial datasheet, the "Operating Temperature" is critical. For standard consumer-grade UFS 254 chips, the range is usually . If the chip is automotive-grade, this range will extend to higher temperatures (often up to 105°C).
The UFS BGA 254 is a standardized JEDEC form factor (MO-276) that enables high-speed data transfer through a serial interface. Unlike older eMMC technology that uses a parallel interface, UFS utilizes a LVDS (Low-Voltage Differential Signaling) interface, allowing simultaneous read and write operations. 2.
