VadaTech Selects Tundra Tsi109(TM)Host Bridge for PowerPC(R)

With the Industry's Best System Performance, Power and Cost 
Tsi109 Optimizes Designs for High-Performance Applications

OTTAWA, May 25 /CNW Telbec/ - Tundra Semiconductor Corporation (TSX:
TUN), the leader in System Interconnect, today announced that the Tundra
Tsi109 Host Bridge, the industry's highest performing host bridge for PowerPC,
will be integrated into the VadaTech PMC710 PrPMC (Processor PCI Mezzanine
Card) module, demonstrating Tundra's strength as a leading supplier of host
bridges for PowerPC.
The Tsi109's innovative feature set and high reliability, backed by
outstanding design support, provides designers with:

- Greater overall system performance
- Reduced system design complexity
- Superior power efficiency

The Tsi109 host bridge sets industry benchmarks for performance and power
management through an innovative feature set supported by world-class design
support. This host bridge supports a dual processor bus at 167 MHz, which
enables higher system compute performance. The Tsi109's superior memory
pipeline offers industry-leading memory bandwidth and an optimized PCI-X
interface provides greater I/O-to-memory throughput. In addition to 2.5 Watt
typical power dissipation, the Tsi109 supports DDR2 memory, which makes this
host bridge the ideal choice for high-density, power-sensitive applications.
The combination of the Tsi109's features and reliability with 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.

Superior Performance at a Lower Cost

Tundra's growing portfolio of Host Bridges for PowerPC delivers industry-
leading system performance, power and cost for customers in the wireless and
wireline networking, storage and embedded computing markets. Tundra Host
Bridges offer designers best system performance-per-watt as well as best
system performance-per-dollar and are ideal companion chips for Freescale
MPC74xx high-performance processors. The combination of the Tsi109's rich
feature set and high reliability with Tundra's outstanding design support has
been well received by the industry's leading PowerPC product vendors such as
VadaTech Inc.
Recently announced, the VadaTech PMC710 is a PrPMC that combines the
Tsi109 host bridge with a high-performance Freescale MPC7448 PowerPC processor
to leverage the speed and efficiency of this best-in-class processor. The
PMC710 offers advantages over other solutions due to its flexibility to update
the CPU while maintaining the rest of the subsystem I/O. By using the DDR2-
compliant Tsi109, the PMC710 optimizes key benefits of DDR2 over DDR; lower
system cost, lower power dissipation and better signal integrity. The Tsi109's
high-performance PCI-X bus and memory bus provides the best throughput
available which allows the PMC710 to be the industry's fastest PrPMC
available. The PMC710 has a modular form factor which makes this PrPMC well-
suited for many high-performance, power-sensitive applications.
"Our customers demand high-speed PMCs that minimize power consumption and
reduce overall system costs," said Saeed Karamooz, president and CEO of
VadaTech Inc. "Our PMC710, combined with Tundra's DDR2-compliant host bridge,
delivers the fastest CPU performance while reducing overall system costs due
to the Tsi109's low power consumption - a huge benefit in demanding
environments such as avionics and defense."
Without any need to change I/O software, the Tsi109 provides an excellent
upgrade path to dual processor versions of the PMC. VadaTech will be
integrating the Tsi109 into its Dual CPU PrPMC, the PMC712, which is ideal for
use in high-performance and power sensitive applications in communications,
defense/aerospace, and industrial control. The PMC712 is scheduled to be
released in June 2006. Customers can easily upgrade their Tsi109 to access
higher performance and next-generation I/O connectivity with other Tundra host
bridges such as the Tsi110(TM) with PCI Express(R) connectivity.

ORDERING INFORMATION AND DESIGN SUPPORT TOOLS

The Tsi109 is available in both standard and lead-free packages for
commercial and industrial temperatures. Volume pricing for the Tsi109 is under
$75USD. For documentation, including ordering information, user manuals, and
software drivers, to assist in accelerated development with the Tsi109, go to
