RTL8370N-VB-CG 8-Port Gigabit Ethernet Switch Controller LQFP-128

The RTL8370N-VB-CG is a cutting-edge, single-chip 8-port 10/100/1000Base-T Ethernet switch controller designed by Realtek for high-speed networking applications. It integrates eight high-performance Giga-PHYs and a non-blocking switch fabric into a compact LQFP-128 package with an exposed thermal pad. This IC is engineered for versatility, supporting advanced Layer 2 features such as 802.1Q VLAN, 8-level priority QoS, link aggregation, and port mirroring. Its embedded 4096-entry look-up table and superior memory management technology ensure efficient packet handling even under heavy traffic loads. Whether used as a simple plug-and-play unmanaged switch or a managed controller in an IoT gateway, the RTL8370N-VB-CG provides a robust, low-power solution for modern Gigabit connectivity.

Features:

• 8-Port Integrated PHYs: Supports 10/100/1000Mbps auto-negotiation and MDI/MDIX automatic crossover.
• Non-Blocking Fabric: Delivers full line-speed forwarding and filtering across all ports for maximum throughput.
• Advanced VLAN Support: Features a 4096-entry VLAN table for port-based, tag-based, and protocol-based VLANs.
• Traffic Prioritization: Eight priority queues per port with Strict Priority (SP) or Weighted Fair Queue (WFQ) scheduling.
• Low Power Consumption: Optimized Giga-PHY design with integrated energy-efficient Ethernet (EEE) capabilities.
• Robust Management: Supports SPI Flash, I2C, and SMI interfaces for flexible system configuration and diagnostics.
