Tundra Announces High Performance Host Bridge for PowerPC® with PCI Express

New Tundra Tsi110(TM) Integrates PCI Express to Deliver the Industry's Best System Performance, Power and Cost

OTTAWA, Jan. 17 / -- Tundra Semiconductor Corporation (TSX: TUN), the leader in System Interconnect, today announced the Tundra Tsi110 Host Bridge, the industry's highest performing host bridge for PowerPC. The latest addition to Tundra's industry-leading family of host bridges is optimized for a broad range of applications for the wireless and wireline networking, storage and embedded computing markets.

The Tsi110 Host Bridge sets industry benchmarks for performance and power management through an innovative feature set supported by world-class design support. Ideal for power sensitive and cost sensitive applications, the Tsi110 integrates several communications peripherals - including two 4-lane PCI- Express ports, four Gigabit Ethernet ports and one PCI-X port. This high level of integration offers system designers numerous options for I/O connectivity and reduces external component count.

Included in the Tsi110's innovative feature set is Gigabit Ethernet hardware acceleration, which off-loads the host processor and allows the four Gigabit Ethernet ports to run at full line rate for data plane applications. The Tsi110 packaging, ball map, and I/O features were all designed with reliability and signal integrity in mind to ease the challenge of high-speed board designs. The Tsi110 is also software compatible with the Tsi109(TM) and Tsi108(TM), allowing software reuse and accelerating development cycles. The combination of the Tsi110's features, reliability and Tundra's world-class support provides designers with the benefits of greater overall system performance, reduced system design complexity, better integration and superior power efficiency.

"Tundra continues to innovate in this space, and along with the industry, predicts strong growth in the scope of PowerPC's leadership in the markets we serve," says Rick O'Connor, Tundra's chief technology officer. "Tundra is the leader in delivering System Interconnect solutions for greater system performance, power and cost benefits that designers need to build high- performance, scalable designs."

Tsi110 Host Bridge Well Received By Leading PowerPC Processor Vendors

The Tsi110 offers best system performance-per-watt as well as best system performance-per-dollar, making it an ideal companion chip for both Freescale MPC74xx and IBM PPC750xx high performance processors. The combination of the Tsi110's rich feature set, high reliability and Tundra's accessible design support has been well received by the industry's leading PowerPC processing vendors such as, IBM.

"Tundra's new Tsi110 host bridge, when combined with our high-performance MPC7447A/7448 processors, allows customers to leverage high-performance processing performance while optimizing system power," said Glenn Beck, market segment manager for Freescale Semiconductor's Digital Systems Division. "With the PCI Express interface, the Tsi110 enables even more design flexibility for our embedded networking customers and opens up possibilities for greater adoption in a range of applications."

"Tundra's latest addition to their host bridge family is good news for Power Architecture(TM). The new Tsi110 host bridge aligns well with IBM's high performance 750 PowerPC processors," said Ron Martino, director of PPC Standard Products, IBM Systems and Technology Group. "When combined, these technologies offer embedded system designers superior performance and power efficiency required to build optimized systems for a range of next-generation applications."


The Tsi110 Host Bridge will be available for sampling late in 2006 through Tundra's worldwide sales network. Volume pricing for the Tsi110 is under $80USD.
