Rtl9210b Datasheet !free!
Overview
- Errata: Check for PCIe link training failures on specific SSD controllers (Phison/Silicon Motion).
- Firmware Version table: Realtek frequently updates the datasheet to reference firmware build numbers (e.g., v1.32.49) – the silicon is fixed, but features depend on firmware.
- SPI Flash programming timing: Ensure the datasheet specifies the hold time for power loss during firmware update.
3.1. Power States
The RTL9210B implements aggressive power gating. The datasheet indicates support for multiple low-power states, including USB Selective Suspend and ASPM (Active State Power Management) for the PCIe link. This allows the drive to enter a deep sleep state when idle, significantly reducing heat generation and preserving the lifespan of the attached NAND flash memory. rtl9210b datasheet
One of the most praised aspects of the RTL9210B is its thermal efficiency. The datasheet specifies an active power consumption significantly lower than previous generations. It also features: Overview
- USB 3.0 Controller:
Formatting: New SSDs will not show up in File Explorer until they are initialized. Use Disk Management (Windows) or Disk Utility (macOS) to format the drive. Troubleshooting & Maintenance Errata: Check for PCIe link training failures on
Customization: Supports customized LED behavior (frequency/duty cycle), UART, GPIOs, and external SPI Flash for firmware storage. Performance Comparisons
- USB 2.0 Interface: The RTL9210B supports USB 2.0 High-Speed (480 Mbps) and Full-Speed (12 Mbps) interfaces, compatible with USB 1.1 and USB 2.0 hosts.
- Ethernet Interface: The chip supports IEEE 802.3/802.3u standards, with a 10/100 Mbps auto-negotiation Ethernet PHY.
- Single-Chip Design: The RTL9210B integrates all the necessary components, including the MAC, PHY, and USB interface, into a single chip, reducing the need for external components.
- Low Power Consumption: The chip has a low power consumption design, making it suitable for battery-powered devices.
