is a 68-pin QFN "green" package controller that integrates several key power and interface components directly onto the silicon.
Supports advanced power states including , CLKREQ, and L1 substates.
The is a high-performance, low-power USB bridge controller designed to bridge USB 3.2 Gen2 to either PCIe Gen3 x2 (NVMe) or SATA Gen3 . As of 2021, it established itself as the industry standard for "dual-protocol" M.2 SSD enclosures, solving many of the compatibility and overheating issues found in earlier bridge chips. Technical Specifications & Hardware Capabilities RTL9210B-CG rtl9210b datasheet 2021
Supports SATA Gen3 (6Gbps) with full backward compatibility for Gen2 and Gen1. Power Management:
Integrated support for Type-C connectors, external SPI Flash (up to 32MB), UART, I2C, and customized LED behaviors. RTL9210B vs. RTL9210 (Non-B Variant) is a 68-pin QFN "green" package controller that
The most significant update found in the 2021 datasheet is the "B" variant's . While the original RTL9210 was NVMe-only, the
Ultra-low power mode (approximately 12.5mW) helps prevent overheating in compact enclosures. As of 2021, it established itself as the
USB 3.2 Gen2 (formerly USB 3.1 Gen2), providing theoretical bandwidth up to 10Gbps . Storage Protocols:
