To understand the pinout, one must first understand the architecture. eMMC relied on a parallel bus (8 data lines) to transfer data. UFS uses a serial interface with differential signaling, similar to SATA or PCI Express, but specifically optimized for low power consumption.
The reballed chip is inserted into a specialized UFS IC socket reader (e.g., EasyJtag Plus, Medusa Pro II, or MiPi Tester). These hardware boxes contain native high-speed UFS controllers capable of interfacing directly with the chip's internal pin configuration to read the partition tables and extract files safely. ufs 3.1 pinout
The specialized pinout of UFS 3.1 supports several advanced power and performance features introduced in the 3.1 standard: To understand the pinout, one must first understand
