VIA Networking Launches the Atlantic VT6528 Ethernet Switch Controller

VIA Networking Technologies today announced the VIA Networking Atlantic VT6528 Ethernet 26-port single-chip switch controller featuring advanced management and security technologies.

Building on the family of VIA Networking Atlantic switch solutions, the Atlantic VT6528 is designed for flexible implementation into small to medium sized commercial networks, featuring twenty-four 10/100Mbps Ethernet ports to connect network stations and two 10/100/1000Mbps ports supporting fiber optic and copper Gigabit lines.

The Atlantic VT6528 also introduces the VIA Networking Advanced Packet Classifier technology for implementing network security applications to help protect against illegal network access, virus and DoS attacks. The switching engine performs forwarding and filtering at full wire speed, features advanced rate control, embedded packet buffer, MAC address tables that allow unicast or multicast address storage, and support for a wide range of IEEE 802.1 and 802.3 standards, including VLAN support.

The VIA Networking Atlantic VT6528 switch controller is a non-blocking store-and-forward shared memory Layer-2+ switched Ethernet controller fully compliant with the latest networking standards. SMII and SS-SMII interfaces connect with three Octal PHY devices, enabling connections to twenty-four 10/100MbpsBaseX ports, while two 802.3z and 802.3ab compliant Gigabit ports with GMII and TBI interfaces can connect Gigabit PHY devices or SERDES transceivers.

The feature set also includes by-port egress/ingress bandwidth control, broadcast storm filtering, 16-bit PIO host interface with three DMA channels, HOL blocking prevention, 802.3ad aggregation and multiple line segments with flexible load balance, and advanced congestion control. For VLAN support, the VT6528 complies with 802.1Q for multiple spanning trees and 4k VLAN with a full PVID range, as well as asymmetric VLAN membership. The VT6528 also features jumbo packet support on a per port or VLAN basis, and enables easy IPv6 implementation into existing network infrastructure through effective IPv6 traffic forwarding, and alleviates concerns about ever-growing network size by supporting Multiple Spanning Trees, while Layer 3 assist support includes multicast routing protocols, IP multicasting and alternative packet prioritizations.

Designed for seamless integration by system builders, the VT6528 can be configured as an intelligent or smart switch with support for an 8/16bit CPU ARM-7 or 8051 processor interface. The chip is offered in a 208-pin LQFP package that features an exposed PAD to facilitate power spreading.

Samples of the VT6528 switch controller are available now.
