Rtl9210b Datasheet 2021

Built-in AES-128/256 hardware decryption engine for secure storage Programmable status pins for Read/Write and Suspend states Clock Source Requires an external 25 MHz crystal oscillator 3. Power Management and Thermal Optimization

The chip actively transitions between USB power modes to protect mobile host devices (like laptops and smartphones) from excessive battery drain: Full operational, maximum throughput mode.

allows a single enclosure to work with both NVMe and SATA M.2 SSDs. Primary Protocol PCIe NVMe only Primary Protocol PCIe NVMe & SATA SATA Support SATA Support Yes (Gen3, 6Gbps) Max USB Speed Max USB Speed Power Delivery Power Delivery Improved (PD 3.0 on BPD models) Stability and Firmware Enhancements RTL9210B-CG - Realtek

A critical hardware feature is the support for the . This allows the RTL9210B-CG to automatically detect the type of M.2 card installed (NVMe or SATA) and switch to the appropriate operating mode without manual intervention. rtl9210b datasheet 2021

Thermal characteristics (from datasheet):

: Features a PEDET interface that automatically switches modes between PCIe and SATA based on the inserted SSD.

According to the 2021 datasheet, the RTL9210B is housed in a compact, environmentally friendly package designed for high-density surface-mount applications. QFN68 (Quad Flat No-Leads, 68 pins). Primary Protocol PCIe NVMe only Primary Protocol PCIe

Managing the RTL9210B controller often involves keeping its firmware up to date to improve compatibility and stability. In January 2021, firmware was available for download. Over time, a comprehensive library of firmware versions for both RTL9210(A) and RTL9210B models has been compiled by the community, available on platforms like station-drivers.com and GitHub.

USB 3.2 Gen 2 SuperSpeed Plus (backwards compatible with USB 3.2 Gen 1/USB 3.0 and USB 2.0). Bandwidth: Up to 10 Gbps theoretical raw data rate.

When searching for the "2021 datasheet," users are often actually looking for the released that year. In 2021, Realtek released significant firmware updates (specifically versions like 1.28 and 1.29 ) that solved major issues. According to the 2021 datasheet, the RTL9210B is

(from application note AN-2021-09): Via USB firmware update mode (hold RESET# and GPIO12 low during power-on) or using the Realtek Flash Tool over UART.

In real-world testing, the RTL9210B is noted for its thermal efficiency, often running cooler than competitors like the JMicron JMS583.

USB 3.2 Gen2 (formerly USB 3.1 Gen2), providing theoretical bandwidth up to 10Gbps . Storage Protocols:

The RTL9210B set a new standard for consumer NVMe enclosures. By 2022, it became the default choice for brands like Orico, Sabrent, Ugreen, and Startech. The 2021 datasheet served as the foundation for countless open-source tools (e.g., rtl9210b-flasher on GitHub) and custom firmwares that unlocked features like higher spin-down timers and LED customization.
