Overview
Description
The RTL8305SC is a low-power, 5-port 10/100M Fast Ethernet switch controller from Realtek. It integrates Layer 2 switching, auto-negotiation, and MAC/PHY functions in a single chip, supporting store-and-forward architecture.
Key features:
- 5 ports (4x 10/100M PHYs + 1x MII/RMII uplink).
- Supports VLAN, QoS, and port-based traffic control.
- Auto MDI/MDIX for all ports.
- Low power consumption (<1W).
- Optional MII/RMII for external MAC or CPU connection.
Applications include SOHO switches, IP cameras, and embedded networking. It requires minimal external components, reducing BOM cost.
The RTL8305SC is a cost-effective solution for basic Ethernet switching needs. For detailed specs, refer to Realtek’s datasheet.
