LOCAL BUS TO PCI BRIDGE FOR DE-MULTIPLEXED A/D PROCESSORS

V292PBC provides the highest performance, most flexible, and most economical method to directly connect Am29030/40 processors to the PCI bus. V292PBC is also a suitable candidate for a variety of 32-bit de-multiplexed local bus applications based on Motorola, IBM, DEC and Hitachi embedded processors - where a minimal amount of glue logic is required. V292PBC may also be used in systems without a CPU for a generic PCI master/target interface.
