The RTL8380M-CG, RTL8382M-CG, and RTL8382L-CG are new generation Gigabit switches supporting Energy Efficient Ethernet (EEE). The RTL8380M is an 10-port 10/100/1000M switch controller, and the RTL8382M is a 28-port 10/100/1000M switch controller. The RTL8382L is a 26-port 10/100/1000M switch controller. All have an 8-port 10/100/1000M Ethernet PHY embedded. The RTL8380M/RTL8382M/RTL8382L are provided via a 55nm CMOS process in an LQFP-216 E-PAD package. The Memory interface of the RTL8380M/RTL8382M supports DDR1/DDR2/DDR3 and SPI Flash. The RTL8382L supports only SPI Flash. The following table lists the main differences between the RTL8380M/RTL8382M/RTL8382L: The RTL8380M supports two interfaces of one RSGMII or two-pairs of SGMII/1000Base-X. The RTL8382M/RTL8382L support four pairs of serially connected QSGMII interface ports to connect to two Octal Gigabit PHYs (RTL8218B). The RTL8382M also supports one serially connected QSGMII interface port to connect to 1 Quad Gigabit PHY (RTL8214FC). The RTL8380M/RTL8382M/RTL8382L have an embedded 500MHz MIPS-4KEc CPU that supports a 32MByte (max.) SPI flash (Only the RTL8380M/RTL8382M support 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 RTL8380M/RTL8382M/RTL8382L supports two hash algorithms. An independent 512-entry Multicast table supports Layer 2 and IP multicast functions. The RTL8380M/RTL8382M/RTL8382L has 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 RTL8380M/RTL8382M/RTL8382L 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 RTL8380M/RTL8382M/RTL8382L supports per-port ingress/egress bandwidth control and per-queue egress bandwidth control. It has 8 physical queues in each port. The RTL8380M/RTL832M/ RTL8382L 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 RTL8380M/RTL8382M/RTL8382L supports por
