The Tundra Tsi350A™ is an industry standard 32-bit 66-MHz asynchronous PCI-to-PCI bridge available in eutectic or RoHS compliant 208-pin PQFP and 256 BGA packages. The Tsi350A is a competitively priced, low-power device that can be used on existing board footprints using standard 32-bit 66-MHz PCI-to-PCI bridges from Pericom, PLX, and TI.

Fully compatible with the PCI Local Bus Specification (Revision 2.3), the Tsi350A supports two PCI buses operating concurrently with sufficient clock and arbitration pins to support nine PCI bus master devices directly on its secondary interface.

The Tsi350A 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

Compatible with standard 32bit 66MHz PCI-PCI Bridges

Pin-for-pin and software compatible with standard 32-bit 66-MHz PCI bridges, manufacturers can use their existing PCBs and software with the Tsi350A as a competitively priced alternative.

Low Power

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