Ufs 3.1 Pinout ((link)) 🎯 Top

Data Output True (t) and Complement (c). These are the transmitting (Tx) lines from the UFS device to the host processor. B. Power Supplies

The pins on a UFS 3.1 memory chip are divided into four main functional groups: Power Supply, Data Transmission (MIPI M-PHY), Clock/Control, and Ground/Reserved lines. 1. Data Transmission Lines (MIPI M-PHY Interface)

The core power supply for the internal NAND flash memory array. It typically operates at 2.5V to 3.3V .

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 ufs 3.1 pinout

UFS 3.1 supports speeds up to 11.6 Gbps per lane.

UFS 3.1 supports , meaning it can utilize two sets of these differential pairs to double its bandwidth, reaching sequential read speeds up to 2,100 MB/s . Power Supply Pins :

The reference clock signal supplied by the host. It provides the base frequency synchronization for the M-PHY interface. Data Output True (t) and Complement (c)

: Differential transmit pairs from the host to the UFS device.

Data Input 0 (True/Complement). Differential data input lane 0. Power Supplies The pins on a UFS 3

: The supply voltage dedicated strictly to the high-speed MIPI M-PHY I/O blocks. It operates at 1.2V .

Always use the exact module datasheet and reference design; UFS physical pinouts and required rails are vendor-specific. For implementation, base your PCB and power sequencing on the manufacturer’s documents.

The vast majority of embedded UFS 3.1 devices come in a . The key mechanical parameters are:

Note: While many manufacturers use the JEDEC standard 153-ball layout, always consult the specific datasheet (e.g., Kioxia or Kingston) for the exact model number. 2.1 Essential Signal Pins (M-PHY)
