Ufs 3.1 Pinout

UFS 3.1 operates at G4 rates (11.6 Gbps). This is in the microwave frequency domain. Standard eMMC routing rules will fail.

| Group | Key Pins | Purpose | |-------|----------|---------| | | VCC (3.3V), VCCQ (1.2V/1.8V), VCCQ2 (1.8V) | Core flash memory, controller logic, and I/O interface power | | High-Speed Data | UFS_RX_P, UFS_RX_N, UFS_TX_P, UFS_TX_N | Differential receive/transmit lanes (M-PHY gear 4) | | Control & Clock | REF_CLK (26 MHz typical), RST_n | Reference clock and hardware reset | | Auxiliary & Strapping | Boot_LD, Boot_EN, RPMB_Key, CMD (legacy), VDDi | Boot mode selection, security, and voltage configuration | ufs 3.1 pinout

The UFS 3.1 pinout is defined around . Successful interfacing requires strict power sequencing, clean differential routing, and correct reference clock. Always obtain the chip's dimensioned ball map (from datasheet or board schematic) before soldering or probing. | Group | Key Pins | Purpose |
