The RTL8330M is a new generation 8-port FE switch controller with embedded 8-port FE PHYs provided via a 55nm CMOS process in an LQFP-216 E-PAD package. The RTL8330M also supports 1 pair of RSGMII or 2 pairs of SGMII/1000Base-X/100Base-FX.
The RTL8330M has an embedded 500MHz MIPS-4KEc CPU that supports a 32MByte SPI flash (max.). The Memory interface supports DDR1/DDR2/DDR3. Two 16C550 compatible UARTs are integrated for low speed serial data, and one E-JTAG is supported for on-chip debugging.
There are 8K entries in the 4-way hash L2 table for MAC address learning and searching. The RTL8330M supports two hash algorithms. An independent 512-entry Multicast table supports Layer 2 and IP multicast functions.
The RTL8330M have a 4K-entry VLAN table for 802.1Q port-based, protocol-and-port-based, 802.1Q-based, IP-subnet-based, and ACL Rules-based VLAN operation to separate logical connectivity from physical connectivity. Support is provided for IVL (Independent VLAN Learning), SVL (Shared VLAN Learning), and IVL/SVL (both Independent and Shared VLAN Learning) for flexible network topology architecture. The RTL8330M supports a 1.5K-entry Access Control List (ACL) that parses various protocol packet types and performs configurable actions, e.g., Permit/Drop, redirect, and traffic policing.
The RTL8330M supports per-port ingress/egress bandwidth control and per-queue egress bandwidth control. It has 8 physical queues in each port.
The RTL8330M provides three types of packet scheduling; SP (Strict Priority), WFQ (Weighted Fair Queuing), and WRR (Weighted Round Robin). Each queue provides a leaky-bucket to shape the incoming traffic into the average rate behavior.
Port-based 802.1X and MAC-based 802.1X authentication prevent unauthorized users from accessing internal servers. The RTL8330M supports port isolation to enhance port security. The RTL8330M also supports a 4-set port mirror configuration to mirror ingress and egress traffic. For network management purposes, complete MIB counter support reflects the switch status in real time. Support is provided for link aggregation to increase link redundancy, and increase linear bandwidth.
The RTL8330M adopts advanced technologies such as Realtek Cable Test (RTCT), Automatic loop detection and prevention (RLPP/RLDP), Attack Prevention, and MAC Address Learning Constraints. The RTL8330M supports Energy Efficient Ethernet (EEE).
