Integrated Device Technology Inc. (IDT) has debuted its RC32438 integrated communications processor that incorporate a 32-bit MIPS CPU core with a DDR memory controller, which provides a higher memory bandwidth compared to an SDRAM-based solution.

A member of the company's Interprise family, the processor also integrates a 32-bit v2.2 PCI controller and two on-chip Ethernet interfaces that frees up bandwidth for use by other peripherals, improving system bandwidth and reducing overall system cost.

The device is designed to deliver enhanced system bandwidth to communications applications within the enterprise and access market segments, including desktop/workgroup switches, gateways, wireless access points, and VPN equipment.

Boosting the bandwidth

IDT is focusing on boosting bandwidth because of the growing requirements for higher sustained data rates and increased processing of data passing through the system. For example, Layer-2 desktop switching platforms are starting to support GbE LAN connections in addition to the 10/100 Mbps connections previously deployed, and are also starting to incorporate certain Layer-3 data processing functions.

In addition to the increasing performance demands in the Ethernet switch arena, wireless access points in the enterprise are evolving to dual-mode radios and higher throughput 802.11 standards, and enterprise gateways are integrating security functionalities on-chip.

The RC32438 also includes logic that allows the monitoring of transactions on the IPBus. It is backward-compatible with the company's existing products and comes with either VxWorks or Linux as the embedded operating system.

It is available in a 416-ball BGA package with speeds ranging of 200MHz, 233MHz and 266MHz, and operating temperatures at the commercial or industrial temperature ranges. Pricing starts at $25.
