Ufs 3.1 Pinout Portable

Decoupling capacitors must be placed as close as humanly possible to the VCC , VCCQ , and VCCQ2 pins on the PCB layout to suppress voltage ripple during massive burst write operations.

The BGA153 ballmap is arranged as a 13 × 13 grid (rows A–M, columns 1–13), with some balls omitted to create a “depopulated” pattern that prevents reverse assembly. The UFS 3.1 interface uses a relatively small number of active signals, which can be grouped into several functional categories.

Unlike older parallel standards like eMMC, UFS 3.1 uses a that significantly reduces the number of required signal pins while boosting performance. UFS 3.1 Pin Configuration (153-Ball FBGA)

Unlike older eMMC storage which heavily relies on a parallel bus interface, UFS utilizes a high-speed serial interface based on the MIPI M-PHY physical layer and MIPI UniPro link layer protocol. ufs 3.1 pinout

For PCB designers working with UFS 3.1, the pinout dictates strict layout rules due to the high frequencies involved (up to 11.6 Gbps per lane in Gear 4).

The reset line should be pulled up to VCCQ (1.2 V) with a 10 kΩ–100 kΩ resistor to ensure it remains de‑asserted during power‑up. When connecting a level‑shifted version of the platform reset, be mindful of signal integrity to avoid false resets.

True and Complement pins for receiving data from the host (Host to Device, Lane 0).

A high-precision reference clock signal (usually 19.2 MHz, 26 MHz, 38.4 MHz, or 52 MHz) supplied by the host processor (SoC) to synchronize the M-PHY state machine.
