Tundra Semiconductor has unveiled comprehensive new product lines to advance its Tundra System Interconnect strategy.
Reference design supports comms processor on PCI
The Wind River PPMC8260 reference design supports designs using the Tundra PowerSpanTMII multiport PCIbus switch for PowerQUICC II microprocessor architectures.
"The Tsi85x family is targeted at a host of high bandwidth applications such as, switches/routers, optical networking equipment and wireless infrastructure", stated Rick O'Connor, Chief Technology Officer of Tundra.
"Because of our knowledge of our customer base as well as our expertise in the way host bridges are used in these applications, our development team has focused the Tsi85x architecture on minimising the latency between the processor and memory".
Based on the proven technology of Tundra PowerSpan, which has recorded over 200 design wins, the Tsi85x family provides software compatibility with PowerSpan and PowerPro, ensuring communications equipment infrastructure vendors low-risk design and significant time-to-market advantage in the development of next-generation products.
In addition, the Tsi85x product line significantly cuts board space requirements, power consumption and design cycle times.
Through the single and dual 66MHz PCI versions of the Tsi85x family, designers can select a host bridge optimised to the topology of their specific equipment, select from a broad speed/power range of PowerPC host processors, lower overall transaction latencies, and connect to a wide variety of high performance I/O peripherals.
The Tsi85x supports read latencies as low as six clock cycles.
The Tsi85x family enhances the Tundra system interconnect roadmap, by supporting next-generation 2.5/3.3V 75x and 74xx PowerPC microprocessors.
Additional features include multiport DMA, nontransparent PCI-to-PCI transactions, concurrent read transactions, processor and PCI arbiters, and CompactPCI hot-swap support.
Prototype samples are scheduled to be available at the end of 2001, with production slated to begin mid-2002.
Pricing starts at $50 US in 10K quantities.
The Tsi85x family will include the Tsi850, a single 64bit PCI device, and the Tsi852TM, a dual 32bit PCI device.
Each will be available in a 31mm PBGA.
The Tsi854TM, a dual 64bit PCI device, will be available in a 35mm PBGA.
