Deep sleep mode utilized when the host operating system enters standby, dropping current draw to milliamperes. Storage Link Power States
is a high-performance, dual-protocol USB bridge chip that serves as a critical link between USB interfaces and storage controllers. Introduced as an evolution of the NVMe-only RTL9210, the "B" variant gained prominence in 2021 for its versatility, supporting both and SATA protocols in a single device. By automatically switching between modes via a mechanical PEDET interface, it allows users to use a wide variety of M.2 SSDs in a single enclosure. Key Technical Specifications rtl9210b datasheet 2021
Compliant with NVM Express (NVMe) Base Specification Rev. 1.3. Deep sleep mode utilized when the host operating
The is a high-performance USB bridge controller designed to connect M.2 SSDs to a host via a USB 3.1 Gen 2 interface . Released as an update to the original RTL9210, it is notably a "dual-protocol" bridge, supporting both NVMe (PCIe) and SATA M.2 drives through a single controller. Core Specifications (2021 Data) By automatically switching between modes via a mechanical
USB differential traces must maintain a strict 90-ohm differential impedance. PCIe traces require 85-ohm differential impedance, while SATA traces require 100-ohm differential impedance. Capacitor Placement: Decoupling capacitors ( ) must be positioned as close as possible to the VDD10cap V sub cap D cap D 10 end-sub VDD33cap V sub cap D cap D 33 end-sub pins to filter out high-frequency switching noise.
Facilitating quick M.2 drive imaging. 5. Performance and Reliability
