Mass Storage Features: Supports both UASP (USB Attached SCSI Protocol) for faster transfers and BOT (Bulk-Only Transfer) for older system compatibility. rtl9210b datasheet
Package and Temperature Range
The RTL9210B is the "sweet spot" controller for USB 3.2 Gen 2 enclosures. It offers better thermal management than the JMS583 and is widely supported by the community for firmware updates. While a formal datasheet is restricted, its widespread adoption in commercial M.2 enclosures ensures it is a reliable choice for DIY projects. Package type: 48-pin QFN Package size: 6mm x 6mm
The chip automatically senses whether a SATA or NVMe M.2 SSD is inserted. It switches the internal logic without requiring physical jumpers or firmware toggles. Low Power Consumption & Thermal Management commonly used in devices from SSK
While a formal "one-piece" public datasheet is often restricted by Realtek to signed NDAs, technical guides and enthusiast-archived files typically outline its core capabilities: Key Technical Specifications
