The Tundra Tsi340™ is an industry-standard 32-bit, 66-MHz synchronous PCI-to-PCI bridge available in a RoHS compliant, 128-pin PQFP package. The Tsi340 is a high-quality, small form-factor, low-power device backed by Tundra’s world-class service and support. The device can be used on existing board footprints using 128-pin PQFP PCI-to-PCI bridges as a competitively priced alternative.

Fully compatible with the PCI Local Bus Specification (Revision 2.3), the Tsi340 supports two PCI buses operating concurrently with sufficient clock and arbitration pins to support four PCI bus master devices directly on its secondary interface.

The Tsi340 makes it possible to extend a system’s load capability limit beyond that of a single PCI bus by allowing board designers to add more PCI devices or more PCI option card slots than a single PCI bus can support.

Business Benefits

Support and Service

The Tsi340 is backed by Tundra’s world-class service and support. Tundra offers customers short lead times, reliable supply, and exceptional customer service and support.

Compatible with Small Form-factor PQFP PCI-to-PCI Bridges

Pin-for-pin and software compatible with other 128-pin PQFP PCI bridges, manufacturers can use their existing PCBs and software with the Tsi340 as a high-quality, competitively priced alternative.

Low Power

Reduce power dissipation: simplify power supply demands and reduce system costs.
