Rtl9210b Datasheet Jun 2026

Supports SuperSpeed Plus (10 Gbps) transfer rates.

The is a high-performance, low-power USB-to-PCIe Gen3x2 and SATA Gen3 bridge controller . It serves as the primary component inside modern dual-protocol M.2 SSD enclosures. By combining native Support for both NVM Express (NVMe) and SATA protocols into a single chip, the RTL9210B eliminates the need for distinct hardware enclosures.

: Supports Bulk Only Transfer (BOT) and USB Attached SCSI Protocol (UASP) for improved data transfer efficiency.

Supports UART, I2C, GPIOs/eFUSE, and external SPI Flash for firmware. Key Features & Operation

: Integrated with USB Type-C and supports the USB 3.2 Gen2 specification .

Section D — Signal Integrity & Layout (15 points)

PCIe Gen3 x2 (up to 16Gbps bandwidth internally). SATA Mode: SATA Gen3 (up to 6Gbps bandwidth).

A key differentiator for the is its integrated USB Power Delivery (PD) controller. This variant enables:

While they look similar, the "B" variant is a significant upgrade for compatibility: Compatibility: The original RTL9210 (non-B) only supports . The RTL9210B adds support for M.2 drives. Auto-Switching:

In conclusion, the RTL9210B datasheet provides a comprehensive overview of the chip's features, specifications, and applications. The RTL9210B is a highly integrated, high-performance USB-to-PCI bridge chip that enables developers to create high-speed data transfer solutions. With its low power consumption, compact package, and multiple operating system support, the RTL9210B is an ideal solution for various applications.

(5 pts) Define the typical safety, reliability, or compliance-related sections present in a datasheet (e.g., ESD ratings, RoHS, temperature ranges). Explain how these influence product certification and field reliability.

Automatically detects whether an NVMe (M-Key) or SATA (B+M Key) SSD is plugged into the M.2 slot.

In the world of external storage, most chips were specialists. You had your high-speed NVMe controllers for the elite SSDs and slower SATA controllers for the old guards. Then came the Realtek RTL9210B Go to product viewer dialog for this item.

For hardware engineers designing a PCB, the physical specifications are critical. The RTL9210B-CG comes in a with a compact footprint of 8mm x 8mm.

Would you like a specific excerpt (e.g., power sequencing table or pinout description) extracted from the datasheet for a deeper dive?

, portable SSDs can easily achieve real-world transfer speeds exceeding

It plays well with a wider variety of host controllers (Intel, AMD, and Apple Silicon).
