Embedded board farms out I/O to save space
The 100 x 72mm VIA EPIA P700 is based on the VIA VX700 unified digital media IGP chipset and is powered by a 1GHz VIA C7 or fanless 500MHz VIA Eden ULV processor.
The Atlantic VT6528 also introduces the unique VIA Networking Advanced Packet Classifier technology for implementing network security applications to help protect against illegal network access, virus and DOS attacks, a major concern for network operators.
Driving the network data is a high-performance switching engine that performs forwarding and filtering at full wire speed, featuring advanced rate control, embedded packet buffer, MAC address tables that allow unicast or multicast address storage, and support for a wide range of IEEE802.1 and 802.3 standards, including VLAN support.
"Protecting commercial networks while ensuring smooth service is becoming more and more difficult in our pervasively networked economy, so it is vital that administrators have increasingly sophisticated tools at their fingertips", said Steven Lee, CEO of VIA Networking Technologies: "The Atlantic VT6528 is the ideal broadband access switch solution, combining management control and enhanced security with the network performance required for today's small and medium sized businesses".

The VIA Networking Atlantic VT6528 switch controller is a nonblocking 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 10/100Mbit/s ports, and two 802.3z and 802.3ab compliant gigabit ports with GMII and TBI interfaces can connect gigabit PHY devices or serdes transceivers.
VIA Networking's proprietary Advanced Packet Classifier (APC) technology enhances network security, implementing a 256-entry deep access control list (ACL) for packet filtering, providing administrators with control over not only who can access the network but also what a user can do with the access privilege, with two linked MIB counters for detecting DOS attacks, as well as more effective virus attack protection, and Layer 2, 3 and 4 QoS support.
The extensive feature set also includes by-port egress/ingress bandwidth control, broadcast storm filtering, 16bit 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, and Layer 3 assist support includes multicast routing protocols, IP multicasting and alternative packet prioritisations.
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.
