Active-low hardware reset. This must be high (1.8V) for normal operation. A glitch here can simulate a dead chip.
TX and RX lanes must be designed with strict 100Ω differential impedance (50Ω single-ended). ufs 3.1 pinout
* * Use open-source hardware databases (e.g., from Pine64 or Raspberry Pi CM4 carrier boards) or schematics of older flagship phones (Google Pixel 6, OnePlus 9) which often leak detailed UFS pinouts. Active-low hardware reset
is the standard for high-performance embedded storage found in flagship smartphones (e.g., Samsung Galaxy S21/S22, OnePlus 9/10) and automotive systems. Unlike eMMC, UFS uses a full-duplex serial interface (MIPI M-PHY) supporting separate read and write lanes, offering theoretical speeds up to 2,900 MB/s. TX and RX lanes must be designed with
The UFS 3.1 pinout is designed for high-bandwidth, low-power data transmission. With a standardized 153-ball arrangement, it allows for high-speed differential data lanes ( ), precise clocking (
Reference clock input (square wave) required for High-Speed (HS) modes. RST_N: Hardware reset signal (active low).
