Tundra Tsi108A Features Dual Processor Support and Power Management

6/17/2005 - Tundra Semiconductor Corporation (TSX:TUN), the leader in System Interconnect, extended its leadership host bridge family for PowerPC to include dual processor support and power management features. With best system performance, best system cost, best system power, and best signal integrity, the Tundra Tsi108A also features integrated spread spectrum clock generation and DDR2 memory support.

Closely following the launch of the Tsi108(TM) in March, the Tsi108A is the latest addition to Tundra's growing portfolio of host bridges for PowerPC that deliver industry-leading system performance, power and cost for customers in the communications, pervasive computing, military, and industrial automation markets. Building on a decade of investment and expertise in PowerPC, Tundra host bridges, which include among others the Tsi106(TM), Tsi107(TM) and Tsi108, are the industry's leading companion chips for Freescale Semiconductor and IBM's high performance PowerPC processors.

Increased Performance and Functionality while Offering the Industry's Best System Power and Cost Host bridges interconnect PowerPC processors with subsystems, and are a critical component in embedded designs. The ideal companion chip for both Freescale MPC74xx and IBM PPC 750xx PowerPC processors, the Tsi108A is an advanced host bridge with patent-pending technology. Capable of supporting two processors and operating up to 200MHz, designers gain exceptional increases in performance as well as a high level of configurability with the Tsi108A.

The Tsi108A joins the Tsi108 as the only host bridges for PowerPC to offer DDR2 memory support. With projected cost savings and power savings of up to 50 percent compared with DDR memory, DDR2 also offers other significant advantages such as ease of design and enhanced signal integrity and reliability benefits. The Tsi108A follows in the footsteps of the Tsi108 with a focus on offering best signal integrity benefits to customers. The Tsi108A packaging, ball map, and I/O features were all designed with signal integrity in mind to ease the challenge of high-speed designs faced by customers. Prior to designing with the Tsi108 and Tsi108A, designers faced challenges in achieving reliable high-speed operation in their PowerPC-based designs.

For demanding low power and cost sensitive applications such as mid to high-end printers, the Tsi108A is the perfect choice. With low active power and integrated features such as clock generation and DDR2 memory support, the Tsi108A offers customers best system performance-per-watt as well as best system performance-per-dollar. And with power management features necessary to meet the stringent idle power requirements of printer and other pervasive computing applications, the Tsi108A is a key component in addressing the low power requirements of these designs.

Tsi108A Well Received By Industry
"Tundra's host bridge portfolio integrates seamlessly with our MPC74xx high-performance PowerPC processors to reduce customer system power while increasing performance," said Glenn Beck, Marketing Director for Freescale Semiconductor's Computing Platforms Division. "The new Tsi108 and Tsi108A host bridges enable even more design flexibility for our embedded networking customers and open up possibilities for pervasive computing applications such as printers and servers."

"Tundra's launch of both the Tsi108 and Tsi108A companion chips aligns with IBM's high performance 750FL and 750GL PowerPC processors. When combined, these technologies provide system designers with building blocks to design optimized systems for a range of power and cost sensitive applications," said Ted Johnson, Marketing Manager, IBM's PowerPC Products. "Tundra's latest addition demonstrates their leadership and investment in advancing the Power Architecture technology worldwide."
