This section is critical for power supply design. According to the 2021 document:
Beyond fundamental data bridging, the 2021 firmware and hardware specifications emphasize security, reliability, and device customization. Custom Firmware via SPI
: Includes a built-in switching regulator (5V to 1V) and LDO (5V to 3.3V) to reduce the need for external components. They were slow
Supports L0s and L1 states, allowing the attached NVMe SSD to drop into lower power bands.
High-speed NVMe operations generate significant heat. The RTL9210B mitigates this via several built-in mechanisms:
Elara almost deleted it. But the word "2021" caught her eye. Most bridge controller chips on the market were running on firmware from 2018 or 2019. They were slow, prone to overheating, and famously incompatible with the new M1 MacBooks that were flooding her workspace.
