Rtl9210b Datasheet [top] Jun 2026

The is a high-performance USB bridge controller designed to act as a versatile link between a USB host and various M.2 storage devices . Its primary appeal lies in its dual-protocol support, allowing it to handle both NVMe (PCIe) and SATA SSDs seamlessly . Key Specifications & Features

The controller supports PCIe ASPM L0s and L1 states. When the SSD is idle, the PCIe lanes are dynamically powered down into a low-leakage state, cutting power consumption by up to 80% during periods of inactivity. USB Link Power Management (LPM) The chip complies with USB LPM U1, U2, and U3 states:
