Features
FE2.1 (Fast Ethernet 2.1) is a hypothetical or less commonly referenced standard, as Fast Ethernet typically follows the IEEE 802.3u (100BASE-TX) specification. However, if referring to a proprietary or updated version, potential features might include:
- Speed: 100 Mbps (standard Fast Ethernet).
- Backward Compatibility: Works with 10BASE-T (10 Mbps) devices.
- Cabling: Supports Cat5/Cat5e UTP or fiber (100BASE-FX).
- Auto-Negotiation: Detects and adjusts speed/duplex automatically.
- Full/Half Duplex: Supports both modes (unlike older Ethernet).
- Improved Latency: Optimized for real-time applications (if enhanced).
- Power Efficiency: Lower power consumption (if updated).
For precise details, verify the exact standard (e.g., IEEE 802.3u or proprietary specs).

Pinout
The FE2.1 is a USB 2.0 hub controller by Terminus Technology. It comes in a 48-pin LQFP package and supports 4 downstream ports. Key functions include:
- USB 2.0 compliance (480 Mbps high-speed, 12 Mbps full-speed).
- Integrated transceivers for all ports.
- Individual or ganged power switching for downstream ports.
- Overcurrent detection and port disable for fault protection.
- TTL-level serial EEPROM interface for configuration.
It requires minimal external components, making it suitable for compact designs.
