Atmel Introduces Gigabit Level 2 Networking Ethernet Switch

2/25/2004 - Atmel® Corporation (Nasdaq: ATML) announced the availability of its unmanaged level 2, Gigabit per second Ethernet Switch. The AT79C1020 Level-2 Gigabit Ethernet Switch has a multi-port MII/GMII interface that supports various speed requirements of 10/100/1000 Mbps. The device is "linkable" to make higher level ports with standard interface that can seamlessly connect to Gigabit PHY. It is fully compliant with IEEE 802.3ab CSMA/CD. AT79C1020 is available for sampling to the customers for integration in their gateway and network switch products.

AT79C1020 is manufactured in low power, cost effective 0.18-micron CMOS technology. It is capable of offering a smooth network migration to a natural upgrade of network capacity through a glue-less connection to the other Gigabit and Fast Ethernet products.

"We have identified increased customer demand for high-bandwidth connections, Gigabit Ethernet has become the leading technology for NIC, switch and networking equipment. An important trend in networking is the migration of packet-based technology from Local Area Networks to Metropolitan Area Networks. The rapidly increase volume of data traffic is challenging the storage and network capacity limits. Atmel's AT79C1020 is the first member of a complete product family for the Network Storage products market." said George Perlegos, Atmel's President and CEO.

AT79C1020 also provides packet switching functions between Multi-port Ethernet ports designed for SOHO (Small Office Home Office) application. It can easily expand the network by "linking" multiple switches. The Gigabit Switch integrates flow control for duplex and backpressure for half duplex. Speed and duplex mode auto-negotiation is done through the MDIO for providing serial management data signal. AT79C1020 on-chip packet buffer supports a Store-and-Forward switching approach that eliminates the need for additional RAM chips as packet buffers. This device supports a wide range of SOHO applications such as standalone home switches, firewall appliances, IP phones, media converters, wireless and wired gateway routers and wireless access points.

"Atmel's switches provide our customers unmanaged configurations ideal for cost-sensitive Gigabit low port count switch systems, wireless, wired firewall routers segment and well suited for point-to-point and mesh network topologies." This product provides easy installation, reduced power consumption and lower network cost. Atmel's new Network Storage Product Business Unit is committed to provide solutions in Data Storage, Network communication and connectivity." said Mehdi Bathaee, Atmel's Network Storage BU's Managing Director.

AT79C1020 is all CMOS device, made in 0.18 micron-CMOS process 160 pin PQFP package that can be available in variety of other packages based on customer's requirement.

AT79C1020 samples are available and priced at $8.95 per 10,000-unit. Atmel also provide reference design to selected customers.
